Exploring the therapeutic potential of precision medicine in rare genetic obesity disorders: a scientific perspective.

The prevalence of obesity is increasing worldwide, affecting both children and adults. This obesity epidemic is mostly driven by an increase in energy intake (abundance of highly palatable energy-dense food and drinks) and to a lesser degree a decrease in energy expenditure (sedentary lifestyle). A small proportion of individuals with obesity are affected by genetic forms of obesity, which often relate to mutations in the leptin-melanocortin pathway or are part of syndromes such as the Bardet-Biedl syndrome.

The metabolic and circadian signatures of gestational diabetes in the postpartum period characterised using multiple wearable devices.

Aims/hypothesis: Gestational diabetes mellitus (GDM) affects 14% of all pregnancies worldwide and is associated with cardiometabolic risk. We aimed to exploit high-resolution wearable device time-series data to create a fine-grained physiological characterisation of the postpartum GDM state in free-living conditions, including clinical variables, daily glucose dynamics, food and drink consumption, physical activity, sleep patterns and heart rate.

Methods: In a prospective observational study, we employed continuous glucose monitors (CGMs), a smartphone food diary, triaxial accelerometers and heart rate and heart rate variability monitors over a 2 week period to compare women who had GDM in the previous pregnancy (GDM group) and women who had a pregnancy with normal glucose metabolism (non-GDM group) at 1-2 months after delivery (baseline) and 6 months later (follow-up).

The effect of levothyroxine (LT4) therapy for subclinical hypothyroidism (SHypo) on appendicular bone geometry and volumetric density has so far not been studied. In a nested study within the randomized, placebo-controlled Thyroid Hormone Replacement for Subclinical Hypothyroidism (TRUST) trial, we assessed the effect of LT4 therapy on bone geometry as measured by peripheral quantitative computed tomography (pQCT). In the TRUST trial, community-dwelling adults aged ≥65 years with SHypo were randomized to LT4 with dose titration vs.

[Vitamin deficiencies in the adult outpatient setting].

Since their discovery more than a century ago to this day, vitamins went from misunderstood molecules with mysterious properties to fundamental components with undoubted clinical implications. Despite the scientific progresses in the understanding of their physiopathological role, vitamins raise to this day multiple interrogations in clinical practice. This article aims at answering questions that are frequently encountered in the outpatient setting regarding vitamin deficiencies: who to screen ? At what moment ? By which test ? How to interpret the results ? How to supplement ? By answering these questions, we hope to provide the general practitioners with a pragmatic tool to guide them in the management of issues related to vitamins.
