Episodes of violence suffered by migrants transiting through Libya: a cross-sectional study in "Médecins du Monde's" reception and healthcare centre in Seine-Saint-Denis, France.

INTRODUCTION: The Central Mediterranean Route, passing through Libya, is one of the most dangerous for migrants. Episodes of violence have been documented but have not been accurately quantified. The objective of the study was to estimate the prevalence of episodes of violence suffered in Libya by migrants consulting the Médecins du Monde reception and healthcare centre in Seine-Saint-Denis (Ile-de-France). METHODOLOGY: A monocentric cross-sectional study was conducted from February to May 2019 including migrants over the age of 18 years who had passed through Libya and arrived in Europe from 2017. The presence of emotional distress was considered as exclusion criterion. The proportion, frequency and factors associated to physical, deprivation and sexual violence in Libya were estimated through a bespoke questionnaire, as well as healthcare access in Libya and psychosocial support needs. RESULTS: Ninety eight people were recruited and 72 were interviewed (17 refused to participate and 9 were excluded). 76.4% were men, with a mean age of 31.9 years, 76.4% had low educational level, 66.7% came from Ivory Coast and 59.7% had left their country for security reasons. The median length of stay in Libya was 180 days. The overall proportion of participants having suffered from violence was 96.4% among men and 88.2% among women. The prevalence of physical, deprivation and sexual violence for men and women were 94.2, 81.7 and 18% and 80.0, 86.7 and 53.3%, respectively. Access to healthcare in Libya was 2.8 and 63.9% of participants were oriented to psychosocial support after the interview. CONCLUSIONS: The vast majority of migrants reported having been victims of violence during their transit through Libya. Women were at particular risk of sexual violence. Access to health care in Libya was almost non-existent. Psychosocial support for this population is urgent.

Water access and attendance for diarrhea in primary health care centers, Gaza strip.

Water access and sanitation has worsened in Gaza strip since the conflict between Israel and Palestine in January 2009. This study aimed to investigate the relationship between attendance for diarrhea to a Primary Health Care Center (PHCC) in Gaza strip and several potential risk factors including water access. A matched case control study with prospective data record was performed. Cases were patients attending a PHCC for diarrhea, and controls were patients attending for any other cause with no diarrhea within the previous three months or since birth. We matched 133 cases and 133 controls, for date of inclusion, age, gender. All patients attended PHCC and were included in January/February 2010. A stool analysis for bacteria and parasites was performed for cases. Of the 266 patients, 62% (166) have to buy water from a private provider. In multivariate analysis, four variables were independently predictive of diarrhea: public water access (OR: 0.046; 95% CI: 0.005-0.454; P=0.0083), poultry or rabbits at home, and presence of cooker at home. A bacterial cause was found in 5.5% (7) and Giardia duodenalis in 20% (26). Treatments did not comply with WHO recommendations. Efforts should be made to improve water access and to implement guidelines for a better management of diarrhea in Gaza strip.

In vitro and in vivo efficacy of sulfo-carrabiose, a sugar-based cosmetic ingredient with anti-cellulite properties.

Most of adult women exhibit cellulite on the hips, buttock and thighs. Although extracellular matrix and lymphatic system disorders can increase its appearance, cellulite basically results from an excessive fat storage in the adipose tissue which exerts considerable pressure on the surrounding skin tissue and creates a dimpled irregular appearance. Caffeine, the most widely used anti-cellulite ingredient, favours fat break-down by inhibiting the phosphodiesterase enzyme and encouraging a high intracellular level of cAMP. A series of studies has shown that spermine and spermidine, two ubiquitous polyamines, encouraged fat storage and slowed fat break-down in the adipose tissue. Besides, it was shown that heparan sulfate glycosaminoglycans had a strong affinity for polyamines. To design a new cosmetic ingredient with anti-cellulite properties, we used molecular modelling to screen several ingredients with a structure similar to that of heparan sulfate glycosaminoglycans. This way, we identified sulfo-carrabiose as a potent molecule for trapping spermine and spermidine. These virtual results were first confirmed in tubo where sulfo-carrabiose was shown to dose-dependently inactivate spermine and spermidine. In vitro, adipocytes cultured with sulfo-carrabiose exhibited a significant reduction of lipogenesis and a significant increase of lipolysis. When sulfo-carrabiose was incorporated in a cosmetic formula, significant improvements were observed in thigh circumference, with better results than those obtained with caffeine after 28 days of use. Furthermore, a combination of caffeine and sulfo-carrabiose led to results significantly better than those obtained with caffeine alone. As measured by fringe projection, thigh volume was also significantly reduced after sulfo-carrabiose treatment. Finally, the appearance of cellulite assessed by clinical evaluation was also significantly reduced within 28 days.
