    Polydrug use was common regardless of the cause of death. In the age group 15 to 24 years, concomitant use of benzodiazepines and illicit drugs, and buprenorphine poisoning were more prevalent than in the age group 25-64 years.

    The unprecedentedly high concomitant use of benzodiazepines in buprenorphine user deaths obscures other possible pharmacological risk factors for buprenorphine poisoning that could be relevant for prevention. Higher mortality in the younger age group suggests particularly unsafe drug use patterns that should be addressed.

    To evaluate the progression of keratoconus in 932 eyes of 659 patients through visual, refractive and topographic data after intracorneal ring segment (ICRS) implantation.

    Retrospective review of 659 patients who underwent ICRS (Intacs®) implantation for keratoconus between September 1997 and November 2017. Demographics, preoperative and postoperative uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA) in LogMAR, corneal topography parameters (thinnest pachymetry, Kmax), central corneal pachymetry and total follow-up time were evaluated. Statistical analysis was performed using IBM SPSS Statistics 24.0 for windows.

    Nine hundred and thirty-two eyes of 659 patients, with a mean age of 30.41 years (range 11-76 years), were evaluated. Mean total follow up time was 3.02 years. Forty-one eyes had a total follow up of over 10 years. Both UCVA and BCVA improved significantly after ICRS implantation (P<0.01). Only 18 eyes (2.66% of eyes of patients under 35 years of age) were found to havCLUSION ICRS implantation showed long-term improvement and stability in visual and topographic results in a large case series of patients with keratoconus. Only a minimal rate of progression was detected in young patients. However, further prospective studies need to be conducted to better define predictability of postoperative visual outcomes and progression.Demodex is a saprophytic mite of the ocular adnexa, which can in certain circumstances proliferate on the skin of the face and on the eyelid margins. It is involved in facial rosacea (especially in the papulopustular form) and in the development or aggravation of anterior and/or posterior blepharitis or even keratoconjunctivitis, often in association with cutaneous lesions ; the pathophysiology is often multifactorial. Symptoms are non-specific, but the presence of cylindrical sleeves on the eyelashes is very suggestive of infestation, and certain techniques of biomicroscopic examination or imaging, such as confocal microscopy in vivo, allow direct visualization of the parasite. Parasitological examination of the eyelashes can confirm the diagnosis and can be improved by good sampling technique. Eyelid hygiene and oil-based ointments are the cornerstone of treatment. New specific treatments, in particular topical treatments based on tea tree oil, ivermectin, as well as pulsed light therapy and micro-exfoliation of the eyelid margin, can help to reduce the parasitic load and improve symptoms.

    To explore the relationship between PR domain containing 16 (PRDM16) gene promoter methylation in abdominal subcutaneous adipose tissue (SAT) and omental adipose tissue (OAT) and obesity.

    Participants were divided into overweight/obesity (33 cases) and normal-weight groups (28 cases). Selleckchem Alexidine PRDM16 promoter methylation in abdominal SAT and OAT were detected. Two independent sample t test, paired t test were used to analyze.

    (1) The methylation levels in overweight/obesity group and normal-weight group were different. There were 3 CpG sites different statistically between two groups. To chr1 2987447 in SAT and chr1 2986395 in OAT, the methylation level of normal-weight group was higher. While to chr1 2987450 in OAT, the methylation level of normal-weight group was lower. (2) The methylation levels in SAT and OAT were different. There were 15 CpG sites different statistically in normal-weight group, and 22 CpG sites in overweight/obesity group. There were 7 CpG sites different statistically in both groups with their methylation levels being higher in OAT than that in SAT. (3) There were 9 haplotypes with statistical significance (8 in SAT, 1 in OAT).

    The methylation degree of PRDM16 gene promoter in abdominal SAT and OAT has the complex relationship with overweight/obesity. The variation of methylation haplotypes combination of multiple sites may play some roles.

PrEP is used by people who are at substantial risk of being exposed to HIV. Numerous clinical trials have confirmed its effectiveness in reducing HIV acquisition and PrEP has been approved and allowed in several countries including France. However, PrEP uptake remains low as concerns about increase in sexual risk behaviour with PrEP use in the wake of a growing epidemic of sexually transmitted infections, and fear of drug resistance have been expressed. As a result, the difference between the proportion of people on PrEP and the proportion of people who would be very likely to use PrEP if they could access it -otherwise known as the PrEP gap- remains high. Nowadays, studies continue to explore long-term effects of PrEP as well as expand the array of available technologies and regimens.Improving dietary quality of supermarket purchases could help reduce obesity and chronic diseases worldwide. In the past decade, there has been increasing academic interest in using behavioral economics strategies, primarily choice architecture, to “nudge” shoppers to make healthier purchases in supermarkets. In a recent study, Young et al. collaborated with a supermarket retailer to test the impact of prominent shelf placement on the sales of healthier breakfast cereals. This well-designed, 12-week product placement intervention did not increase sales of the healthier products. Does this mean healthy supermarket choice architecture does not work? Shelf placement interventions may not be able to overcome customers’ strong preferences for their habitual choices and brands, and in-store displays and promotions may further reduce the effect of these interventions. Healthy choice architecture is more likely to be effective if default choices are compatible with shoppers’ personal preferences or long-term goals, such as saving money or keeping their children healthy.
