Alcohol Consumption and Methylation-Based Measures of Biological Age.

Epigenetic age acceleration is considered a measure of biological aging based on genome-wide patterns of DNA methylation. Although age acceleration has been associated with the incidence of diseases and death, less is known about how it is related to lifestyle behaviors. Among 2316 women, we evaluate associations between self-reported alcohol consumption and various metrics of epigenetic age acceleration.

Associations of Body Composition and Physical Activity Level With Multiple Measures of Epigenetic Age Acceleration.

Epigenetic clocks use DNA methylation to estimate biological age. Whether body composition and physical activity are associated with these clocks is not well understood. Using blood samples collected at enrollment (2003-2009) from 2,758 women in the US nationwide Sister Study, we calculated 6 epigenetic age acceleration metrics using 4 epigenetic clocks (Hannum, Horvath, PhenoAge, GrimAge).

[Frequency of contact sensitization to modern dressings used to treat chronic leg ulcer].

Introduction: Allergic contact dermatitis around chronic leg ulcers (CLU) is a common complication in patients presenting CLU and prolongs healing times. The aim of this study was to describe the rate of sensitization to modern dressings (MD) used in these patients and to assess whether there is a relation between the number of sensitizations and ulcer type, the time from onset of the ulcer, and patient age and gender.

Patients And Methods: We conducted a retrospective study at Reims University Hospital between 2010 and 2014 that included all patients with CLU of vascular etiology surrounded by eczematous lesions, and who had one of the patch-tests in the following 3 series: European baseline±leg ulcers±corticosteroids.

[Lupus erythematosus treatment with belimumab in daily practice: Retrospective study of 15 patients].

Background: Belimumab (an anti-BLyS monoclonal antibody) was recently approved for the treatment of systemic lupus erythematosus (SLE). The aim of the study was to describe efficacy and safety of the drug as well as its impact on serologic parameters and the role of long-term systemic sparing of treatment in clinical practice in LE.

Patients And Methods: We conducted a retrospective study at Reims University Hospital between 2012 and 2016 including consecutive patients with LE treated with belimumab.

[Skin pigmentation induced by meropenem and levofloxacin].

Background: Various cutaneous side-effects, including, exanthema, pruritus, urticaria and Lyell or Stevens-Johnson syndrome, have been reported with meropenem (carbapenem), a rarely-prescribed antibiotic. Levofloxacin (fluoroquinolone), a more frequently prescribed antibiotic, has similar cutaneous side-effects, as well as photosensitivity. We report a case of cutaneous hyperpigmentation induced by meropenem and levofloxacin.
