Is there a role for Notch signalling in human breast cancer?
Aberrant Notch signalling has been observed in several human cancers, including acute T-cell lymphoblastic leukaemia and cervical cancer, and is strongly implicated in tumourigenesis. Unregulated Notch signalling in the mouse mammary gland leads to tumour formation. These results raise the possibility that Notch signalling might play a role in human breast cancer. There are currently few reports that address this question directly and this appears to be an area worthy of further investigation
“Bursting the Lyrica bubble”: experiences of pregabalin use in individuals accessing opioid substitution treatment in Dublin.
Background: Pregabalin, also known by a brand name of Lyrica, is a prescription only gamma-aminobutyric acid (GABA) analogue and licensed for a range of medical conditions, e.g. chronic pain, generalised anxiety and epilepsy. In recent years, pregabalin has attracted clinical and research attention due to an increase in its association with overdose fatalities. Individuals with opiate use and those in opioid agonist treatment are an identified at risk group for problematic pregabalin use and overdose. As such, research focusing on pregabalin use in individuals accessing opioid agonist treatment is highly relevant. Aim: This study aims to add to the evidence base on diverted pregabalin use in the OAT cohort in Ireland. Methods: Fifteen semi structured interviews were conducted and analytically coded using thematic analysis with software programme NVivo12. Results: Individuals on OAT may use Lyrica to self-regulate negative emotions; Lyrica use in this population is embedded in a polydrug use culture of “tablet taking”; participants illustrated concerning reports of inappropriate prescribing and described psychiatric symptoms occurring during withdrawal. Conclusions: We report here on the first study in Ireland investigating the experiences of individuals who access opioid agonist treatment (OAT) and reported current or recent pregabalin use. Increased pharmaco-vigilance amongst medical practitioners is warranted when prescribing Lyrica to individuals with vulnerabilities such as a history of problematic drug use. Trauma informed interventions in addition to pragmatic harm reduction information for poly drug users to prevent cross tolerance, dependence and overdose deaths should be part of the healthcare and policy response
“Saving Face”: An Online Study of the Injecting Use of DIY Botox and Dermal Filler Kits
This study reports on an empirically underdocumented practice in contemporary aesthetic enhancement culture, the self-injection of unregulated DIY Botox and dermal filler kits purchased online. Data were collected from 4 online discussion forums containing disclosures in relation to use of DIY kits and analyzed using ethnographic content analysis. Motivation to source DIY Botox and dermal fillers online was grounded in desire to avoid financial cost of professional services and a lack of confidence in practitioners. Future intentions to order online raw materials and “formulas” to prepare dermal fillers at home were expressed. Individuals taught themselves to inject through watching YouTube tutorials and downloading Botox injection maps from the Internet. Although individuals demonstrated awareness of the health risks involved with self-injection of unregulated products, this was not a deterrent. Future research is warranted to document the injecting practices and health outcomes of individuals who inject DIY Botox and dermal filler kits to inform targeted harm reduction interventions by health-care practitioners. © 2018, The Author(s)
The 3D-printed miniplate-jig system: a new, rapid, precise, and user-friendly approach to miniplate fixation of free-tissue mandibular reconstructions
“A slippery slope”: a scoping review of the self- injection of unlicensed oils and fillers as body enhancement.
Self-injection of a range of oils and fillers for body enhancement dates back to 1899, but due to significant associated harms and fatalities this practice has been largely linked to distinct cultural groups in recent times. This scoping review gathers what is currently known on the self injection of body fillers for aesthetic purposes, using Arksey and O’Malley’s (2005) five stage iterative process scoping review methodology. Thematic manual coding then organised the data into themes through identified patterns: indicative profiling of individuals who self inject body fillers; motivation for use across types of oil injection; sourcing routes and documented harms. It was found that the majority of people who inject body fillers are male and do so to grossly increase muscle size. Injection of oils and other materials in the male genitalia was also described, in addition to female self-injection in the breast, hand and leg areas for augmentation. A range of health consequences were reviewed. Recommendations are made for further research into this unique phenomenon, which although is relatively rare warrant future research attention considering the documented increase in DIY facial fillers and contemporary body image culture
Acute haemoabdomen associated with Angiostrongylus vasorum infection in a dog: a case report
A one-year-old intact female, Danish shorthaired pointer was referred to the emergency service with a history of acute collapse and pale mucous membranes after a month of reduced activity but with no other clinical signs. An ultrasound examination of the abdomen indicated the presence of a large amount of free fluid with no obvious cause such as neoplasia or splenic rupture. Fluid analysis had the macroscopic appearance of blood with no signs of infection or neoplasia. Multiple Angiostrongylus vasorum L1 larvae were revealed on a direct rectal faecal smear. The dog was treated with fenbendazole 25 mg/kg orally once daily for 20 days and given supportive treatment. The dog was stabilised on this treatment. Haemoabdomen is a clinical sign where surgical intervention is often considered an integral part of the diagnostic investigation (i.e., laparotomy) or treatment. Failing to make the diagnosis of canine angiostrongylosis before performing surgery may have a serious adverse affect on the outcome. Consequently, in areas where A. vasorum is enzootic, a Baermann test and a direct faecal smear should be included in the initial diagnostic investigation of all dogs presenting with bleeding disorders of unknown origin
