ABSTRACT
BACKGROUND: Energy drinks (ED) are popular among young people despite evidence of associated health risks. Research into the prevalence and pattern of ED intake among young people is sparse. The present study investigates the prevalence and pattern of ED intake among a large sample of adolescents, including how many consume them, how often, for what reasons and in what contexts. METHODS: In 2018, all students in grades 7-12 attending 25 randomly selected Western Australian schools were invited to complete an online self-report survey about EDs. RESULTS: Of the 3688 respondents, 51.2% reported consuming an ED. Of these 'ever consumers', 23.4% drank them monthly, 19.2% weekly and 2% every day. The average age of first intake was 10.7 years. One-fifth (19.7%) of 'ever consumers' reported consuming more than two EDs in 1 day. Reasons for ED use included taste, to boost energy levels, sport performance and studying. CONCLUSIONS: The findings add to limited international evidence about adolescent ED use and provide valuable information to help ensure interventions to reduce intake address the underlying reasons and contexts of ED consumption.

Musculoskeletal allotransplantion is the most common form of human tissue transplantation. Unlike solid organ transplants, bone allotransplants undergo rigorous processing and are considered non-viable tissue. In this study, we propose that donor genetic material may exist in circulation after bone allotransplantation. Fifty-one female patients who received bone allotransplants from male donors were assessed. Blood plasma samples were analyzed using real-time quantitative polymerase chain reaction (PCR) with dual labeled fluorogenic probes for the presence of the SRY gene on the Y chromosome. Of the total 51 patients, the SRY sequence was detected in 6 patients. Five were positive at day 1 postoperatively and negative thereafter, with the remaining patient positive at 3 months post-transplantation. Our results document, for the first time, the presence of donor DNA in the circulation of recipients after bone allotransplantation. Our findings suggest a potential new investigative tool to assess the postoperative status of bone allotransplants.

We carried out a blinded prospective randomised controlled trial comparing 2-octylcyanoacrylate (OCA), subcuticular suture (monocryl) and skin staples for skin closure following total hip and total knee arthroplasty. We included 102 hip replacements and 85 of the knee.OCA was associated with less wound discharge in the first 24 hours for both the hip and the knee. However, with total knee replacement there was a trend for a more prolonged wound discharge with OCA. With total hip replacement there was no significant difference between the groups for either early or late complications. Closure of the wound with skin staples was significantly faster than with OCA or suture. There was no significant difference in the length of stay in hospital, Hollander wound evaluation score (cosmesis) or patient satisfaction between the groups at six weeks for either hips or knees. We consider that skin staples are the skin closure of choice for both hip and knee replacements.
