BMC Public Health 2016; 16:1070. [PMID: 27724901 PMCID: PMC5057497 DOI: 10.1186/s12889-016-3732-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2016] [Accepted: 09/29/2016] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND Skog's collectivity theory of alcohol consumption predicted that changes in alcohol consumption would synchronize across all types of drinkers in a population. The aim of this paper is examine this theory in the Australian context. We examined whether there was a collective change in alcohol use in Australia from 2001 to 2013, estimated alcohol consumption in non-high risk and high risk drinkers, and examined the trends in alcohol treatment episodes. METHODS Data from the 2001-2013 National Drug Strategy Household Surveys (N = 127,916) was used to estimate the prevalence and alcohol consumption of abstainers, high risk drinkers and frequent heavy episodic drinkers. Closed treatment episodes recorded in the Alcohol and Other Drug Treatment Services National Minimum Dataset (N = 608,367) from 2001 to 2013 were used to examine the trends of closed alcohol treatment episodes. RESULTS The prevalence of non-drinkers (abstainers) decreased to the lowest level in 2004 (15.3 %) and rebounded steadily thereafter (20.4 % in 2013; p < .001). Correspondingly, the per capita consumption of high risk drinkers (2 standard drinks or more on average per day) increased from 20.7 L in 2001 to peak in 2010 (21.5 L; p = .020). Non-high risk drinkers' consumption peaked in 2004 (2.9 L) and decreased to 2.8 L in 2013 (p < .05). There were decreases in alcohol treatment episodes across nearly all birth cohorts in recent years. CONCLUSION These findings are partially consistent with and support Skog's collectivity theory. There has been a turnaround in alcohol consumption after a decade-long uptrend, as evident in the collective decreases in alcohol consumption among nearly all types of drinkers. There was also a turnaround in rate of treatment seeking, which peaked at 2007 and then decreased steadily. The timing of this turnaround differs with level of drinking, with non-high risk drinkers reaching its peak consumption in 2004 and high risk drinkers reaching its peak consumption in 2010.

Abstract
Negative attitudes to aging are a risk factor for poor health and well-being. The current study sought to examine satisfaction with social support as a potentially modifiable factor that might facilitate the development of more positive attitudes to aging. A convenience sample of 501 older respondents (Mage = 72.06) reported on frequency of social support and their satisfaction with it, as well as completing a rating of attachment (model of the self and others), a measure of attitudes to aging, and a number of background measures. Results indicated that better subjective health, younger age, and greater satisfaction with social support were all significant predictors of more positive attitudes to aging, while frequency of social support was not. Model of the self accounted for some variation in satisfaction with social support. Interventions to increase satisfaction with social support in later life, recognizing individual differences and attachment styles, may improve attitudes to aging and further support health and well-being.

Abstract
The objective of this study was to compare feeding behavior between red and black Angus heifers during a 161-d finishing period as a potential explanation for performance differences. Sixty-eight single-sourced purebred red (n = 35) and black (n = 33) Angus heifers, leptin genotype TT, and average starting weight 360 kg (±19 kg) were used. Heifers were randomly and equally allocated into one of two feedlot pens, equipped with five feed bunks that recorded feeding behavior. Individual time spent at the feed bunk, interval between feeding events, feed intake, and meal frequency were recorded daily, and eating rate was calculated. Heifers were fed a barley-based diet (>75% concentrate). After 161 d, at the end of the feeding period, feedlot performance was calculated as average daily gain (ADG) and gain to feed conversion rate. Additionally, carcass data were obtained from the abattoir. Overall, black Angus heifers ate more, spent more time at the feed bunk, and had more meals compared with red Angus (P < 0.001). Red Angus heifers had better gain to feed ratios (P < 0.02) and significantly more red heifers were assigned to Canadian yield category 1 (≥59% lean meat) compared with black heifers (P = 0.02), whereas black heifers had higher back fat thickness throughout the study (P ≤ 0.04). All other performance parameters (ADG and carcass weight) were not different.

Abstract
Purpose
This paper explores the background principles, theories, and components of the QuikFix intervention for primary and comorbid substance use in young people.
Design/methodology/approach
QuikFix is a brief Motivational Interviewing (MI) intervention utilising cognitive-behavioural coping skills training to reduce vulnerability to substance use and comorbid mental health problems in young people. It is delivered in two to three brief sessions including an assessment. A new version, QuikFix PI (Personality Intervention) which incorporates coping skills training targeting, sensation seeking, impulsive, depressive and anxiety personality styles that may underlie primary and comorbid substance use problems is presented.
Findings
The original QuikFix intervention has demonstrated efficacy in young alcohol and cannabis users with comorbid depression and anxiety symptoms. The efficacy of the new personality targeted version of QuikFix is currently being tested in a large randomized controlled trial among young people with alcohol related injuries/illnesses. Future research is required to determine the efficacy of QuikFix PI in comorbid populations including those with behavioural disorders.
Practical implications
QuikFix interventions can be delivered via telephone or face-to-face in clinical settings for clients with primary substance use and comorbid depression and anxiety symptoms.
Originality/value
This paper describes a novel two to three session manualised personality targeted substance use intervention. The full original QuikFix treatment manual is available online (Hides and Carroll 2010).

Abstract
Internationally there is a growing interest in the mental wellbeing of young people. However, it is unclear whether mental wellbeing is best conceptualized as a general wellbeing factor or a multidimensional construct. This paper investigated whether mental wellbeing, measured by the Mental Health Continuum-Short Form (MHC-SF), is best represented by: (1) a single-factor general model; (2) a three-factor multidimensional model or (3) a combination of both (bifactor model). 2220 young Australians aged between 16 and 25 years completed an online survey including the MHC-SF and a range of other wellbeing and mental ill-health measures. Exploratory factor analysis supported a bifactor solution, comprised of a general wellbeing factor, and specific group factors of psychological, social and emotional wellbeing. Confirmatory factor analysis indicated that the bifactor model had a better fit than competing single and three-factor models. The MHC-SF total score was more strongly associated with other wellbeing and mental ill-health measures than the social, emotional or psychological subscale scores. Findings indicate that the mental wellbeing of young people is best conceptualized as an overarching latent construct (general wellbeing) to which emotional, social and psychological domains contribute. The MHC-SF total score is a valid and reliable measure of this general wellbeing factor.

Abstract
Background Most adolescents begin alcohol consumption during adolescence, heavy alcohol use by adolescents is common, and alcohol-related harm amongst adolescents is a major public health burden. Parents are a common source of alcohol amongst adolescents, but little is known about how parental supply of alcohol has changed over recent years. This study examines national trends in parental supply of alcohol to adolescent children in Australia since 1998. Methods Six Australian National Drug Strategy Household Surveys (1998–2013) yielded rates of parental supply of current and first ever alcohol consumed. Lifetime and current alcohol use were also estimated. The surveys were conducted for households across all Australian states and territories. Surveyed adolescents were aged 14–17 years (N = 7357, 47.6 % male). Measures included the reported source of currently consumed alcohol and first ever alcoholic beverage (parents/friends/others), lifetime alcohol use, number of standard alcohol units consumed on drinking days, and frequency of alcohol use. Corrected Pearson chi-squared tests were used to compare survey years. Results There was a significant drop in parental supply of current alcohol use from 21.3 % in 2004 to 11.79 % in 2013 (p < .001). The lower prevalence of parental supply coincided with legislative changes on parental supply of alcohol to adolescents, but causality cannot be established because of the variation in the timing and reach of parental supply legislation, and small samples in some states. There were downward trends in adolescent experimentation, quantity and frequency of alcohol use across years, with the largest drop in alcohol use in 2010 and 2013. Conclusions In Australia, there has been a substantial reduction in parental supply of alcohol to adolescents from 2010, and this factor may partially account for reductions in adolescent alcohol use.

Abstract
INTRODUCTION AND AIMS This study examines the association of alcohol and polydrug use with risky sexual behaviour in adolescents under 16 years of age and if this association differs by gender. DESIGN AND METHODS The sample consisted of 5412 secondary school students under 16 years of age from Victoria, Australia. Participants completed an anonymous and confidential survey during class time. The key measures were having had sex before legal age of consent (16 years), unprotected sex before 16 (no condom) and latent-class derived alcohol and polydrug use variables based on alcohol, tobacco, cannabis, inhalants and other illegal drug use in the past month. RESULTS There were 7.52% and 2.55% of adolescents who reported having sex and having unprotected sex before 16 years of age, respectively. After adjusting for antisocial behaviours, peers' drug use and family and school risk factors, girls were less likely to have unprotected sex (odds ratio = 0.31, P = 0.003). However, the interaction of being female and polydrug use (odds ratio = 4.52, P = 0.004) was significant, indicating that girls who engaged in polydrug use were at higher risk of having unprotected sex. For boys, the effect of polydrug use was non-significant (odds ratio = 1.44, P = 0.310). Discussion and Conclusions For girls, polydrug use was significantly associated with unprotected sex after adjusting for a range of risk factors, and this relationship was non-significant for boys. Future prevention programs for adolescent risky sexual behaviour and polydrug use might benefit from a tailored approach to gender differences. [Chan GCK, Kelly AB, Hides L, Quinn C, Williams JW.

Abstract
OBJECTIVES While early diagnosis of dementia is important, the question arises whether general practitioners (GPs) should engage in direct referrals. The current study investigated current referral practices for neuroimaging in dementia, access to imaging modalities and investigated related GP training in Ireland and North Wales. METHODS A questionnaire was distributed to GPs in the programme regions which included approximately two thirds of all GPs in the Republic of Ireland and all general practitioners in North Wales. A total of 2,093 questionnaires were issued. RESULTS 48.6% of Irish respondents and 24.3% of Welsh respondents directly referred patients with suspected dementia for neuroimaging. Irish GPs reported greater direct access to neuroimaging than their Welsh counterparts. A very small percentage of Irish and Welsh GPs (4.7% and 10% respectively) had received training in neuroimaging and the majority who referred patients for neuroimaging were not aware of any dementia-specific protocols for referrals (93.1% and 95% respectively). CONCLUSIONS The benefits of direct GP access to neuroimaging investigations for dementia have yet to be established. Our findings suggest that current GP speciality training in Ireland and Wales is deficient in dementia-specific and neuroimaging training with the concern being that inadequate training will lead to inadequate referrals. Further training would complement guidelines and provide a greater understanding of the role and appropriateness of neuroimaging techniques in the diagnosis of dementia.

Abstract
Contaminated blood cultures represent challenges regarding diagnosis, duration of hospitalization, antimicrobial use, pharmacy and laboratory costs. Facing problematic neonatal blood culture contamination (3.8%), we instigated a successful intervention combining skin antisepsis using sterile applicators with 2% chlorhexidine gluconate in 70% isopropanol prior to phlebotomy (replacing 70% isopropanol) and staff education. In the six months prior to intervention, 364 neonatal peripheral blood samples were collected. Fourteen (3.8%) were contaminated. In the post-intervention six months, 314 samples were collected. Three (0.96%) were contaminated, representing significant improvement (Fisher's exact test: P = 0.0259). No dermatological sequelae were observed. The improvement has been sustained.

Abstract
Under the umbrella of the National Database for Clinical Trials (NDCT) related to mental illnesses, the National Database for Autism Research (NDAR) seeks to gather, curate, and make openly available neuroimaging data from NIH-funded studies of autism spectrum disorder (ASD). NDAR has recently made its database accessible through the LONI Pipeline workflow design and execution environment to enable large-scale analyses of cortical architecture and function via local, cluster, or "cloud"-based computing resources. This presents a unique opportunity to overcome many of the customary limitations to fostering biomedical neuroimaging as a science of discovery. Providing open access to primary neuroimaging data, workflow methods, and high-performance computing will increase uniformity in data collection protocols, encourage greater reliability of published data, results replication, and broaden the range of researchers now able to perform larger studies than ever before. To illustrate the use of NDAR and LONI Pipeline for performing several commonly performed neuroimaging processing steps and analyses, this paper presents example workflows useful for ASD neuroimaging researchers seeking to begin using this valuable combination of online data and computational resources. We discuss the utility of such database and workflow processing interactivity as a motivation for the sharing of additional primary data in ASD research and elsewhere.

Abstract
Abstract
Background. We have previously reported that ChemoT produces durable (>5 years) CR in a minority of pts with H+MBC, prompting a search for predictive markers. Extensive lymphocytic infiltration of cancers is correlated with high levels of immune gene signatures. International consensus guidelines on TILs define "lymphocyte-predominant BC" at a threshold of S-TILs of 50-60% versus tumour cells. High levels of S-TILs has been correlated with improved outcome in HER2+ early stage BC pts treated with ChemoT. We investigated the degree of S-TIL infiltration in metastatic biopsies from pts with HER2+MBC prior to ChemoT, and attempted to determine whether S-TILs predicted CR in HER2+MBC.
Methods. We searched a database of all pts with HER2+ MBC treated at our institution with anti-HER2 therapy over 15yrs to identify pts who achieved CR according to RECIST 1.0 criteria, which lasted for at least 6 months. We matched them with an equal number of pts from the database who were treated during the same period, but who had progressive (POD) or stable disease (SD) as best response to T. Pts must have at least one pre-treatment tumour sample available for S-TILs assessment, and adequate clinical and follow-up information. S-TILs (mononuclear cells including lymphocytes and plasma cells) contained within the boundaries of invasive tumour were identified on a representative haematoxylin and eosin stained slide and scored as a percentage of the stromal area alone, according to the International TILs Working Group 2014 methodology [Salgado R, 2015]. S-TILs were assessed specifically for this study by a senior pathologist who scored the samples and who was blinded to pts response and clinical details.
Results. Out of 246 MBC pts registered in the HER2+ database we identified 31 CR pts with at least one available pre-treatment metastatic sample. A cohort of 31 matching POD-SD pts was randomly obtained from the same database. In 8 cases (7 CR / 1 POD-SD) S-TILs could not be assessed due to inadequate material, or for other technical reasons. The final study sample is 54 pts (24 CR / 30 POD-SD). Pts characteristics are as follows: median age (range): CR 55 (29-78) / POD-SD 56 (26-89), hormone receptor (HR) pos: CR 12 (50%) / POD-SD 18 (60%), De Novo MBC at diagnosis: CR 13 (54%) / POD-SD 8 (27%) [p<0.05]. All pts received chemotherapy with T (+ lapatinib in 3 pts as part of a clinical trial), and continued on T until POD. Pre-treatment S-TILs >50% were statistically significantly more frequent in CR (50% of pts) than POD/SD (20%) [chi-square p=0.02]. No statistically significant difference in the HR status was observed between the two groups (CR vs POD-SD) or between the high and low S-TILs pts.
Conclusions. S-TILs >50% in the pre-treatment tumour biopsy of HER2+MBC were significantly correlated with subsequent CR to ChemoT, supporting the hypothesis that the immunological effects of T may play a role in determining response. Speculatively, S-TILs might identify pts with a higher likelihood of benefit from T. Further study of the potential role of S-TILs as predictors of T benefit are required.

Abstract
Abstract
Background
Young women (<40 yrs) with breast cancer (YWBC) account for 7-12% of BC diagnoses. BC is the leading cause of cancer death in this group (G). Age-specific data on outcome and appropriate treatment (Rx) are lacking. YWBC appear to have more biologically aggressive subtypes and a higher risk of relapse and death. We studied the clinico-pathological (ClinPath) characteristics in YWBC, examining how outcomes/Rx have evolved.
Methods
YWBC were identified from pathology databases at 2 tertiary centers. Pts were divided into 2 cohorts: BC diagnoses from 2000-2007 (G1) and 2008-2015 (G2). ClinPath and Rx data were retrieved from clinical, radiology and histology databases. Statistical analysis was performed using SPSS.
Results
We identified 347 pts. Tumor features are shown in Table I. Median age is 36 (23-39). By histology, 90.8% (n=315) had invasive ductal carcinoma, 53.1% (n=181) had Grade III BC and 56.3% (n=171) had lymphovascular invasion. Pregnancy-associated BC occurred in 10.7% (n=34). Mastectomy (MX) was performed in 53% (n=176) and axillary lymph node clearance (ALNC) in 63.8% (n=192 [G1: 84.3% vs. G2: 48.6%, p<0.001]).

Pts receiving NAT in G2 trended towards improved pCR rate (G2: 24.6% vs G1: 8.3%, p=0.057). Endocrine Rx alone was received by 9.8% (n=22); 13.6% (n=18) in G2 vs 4.3% (n=4) in G1. OncotypeDx(ODx) was used in 23 pts (14.9%) (median score 17), 1 had a DR (ODx Score = 18).

DR occurred in 50 pts (16%), including 13 (20.3%) HER2+ pts. Of note, 92.3% (n=12) of these were in G1. Relapse rates (RR) in TN and ER+/HER- pts were 19.6% (n=11) and 13.7% (n=26) respectively. There was a higher RR in G1 (34.8% vs 11.4%, p<0.001). Overall survival in pts with stage IV dx was 32 mos in G1 and 48 mos in G2.
Conclusion
In line with existing data, locally advanced dx is more prevalent in YWBC. MX and ALNC rates were high and most received multimodal Rx. The extent of axillary surgery declined. Pts in G2 had lower volume BC at diagnosis suggesting increasing awareness. TN and HER2+ subtypes accounted for a slightly higher proportion of BC cases. Pts with PCR had better outcomes. Only 16% relapsed with metastatic dx. The impact of HER2 Rx is highlighted by reduced RR in HER2+ G2 pts. Outcomes were unchanged in pts with ER+/HER2- and TNBC. These remain a priority for future research.

Abstract
OBJECTIVES Higher levels of cognitive reserve (CR) are associated with better cognitive function in later life. In contrast, depressive symptoms, anxiety, and rumination are associated with diminished cognitive function. There has been limited research to date examining the influence of CR on the relationship between mood and cognitive function, and results are inconsistent. The aim of this study was to investigate the role CR plays in the relationships between mood, rumination, and cognitive function in later life. METHOD Two hundred and thirty-six healthy people aged 60+ completed measures of CR, depression, anxiety, rumination, recall, and verbal fluency. Participants were dichotomised at the median into those with lower and higher levels of CR. RESULTS CR, mood, and rumination together accounted for between 13% and 15.6% of the variance in scores on the cognitive tasks in the sample as a whole. Mood and rumination explained a significant amount of variance in cognitive test scores in those with lower levels of CR, but not in those with higher levels of CR. CONCLUSION The way in which mood and rumination are related to cognitive function differs depending on the individual's level of CR. These results support the view that it is important to continue to build on CR as people move into later life in order to maintain cognitive health.

Abstract
Key components of cognitive lifestyle are educational attainment, occupational complexity and engagement in cognitively stimulating leisure activities. Each of these factors is associated with experiencing fewer depressive symptoms in later life, but no study to date has examined the relationship between overall cognitive lifestyle and depressive symptoms. This task is made more complex because relatively few older participants in cross-sectional studies will be currently experiencing depression. However, many more will show evidence of a depressive thinking style that predisposes them towards depression. This study aimed to investigate the extent to which cognitive lifestyle and its individual components are associated with depressive thoughts and symptoms. Two hundred and six community-dwelling participants aged 65+ completed the depressive cognitions scale, the geriatric depression scale and the lifetime of experiences questionnaire, which assesses cognitive lifestyle. Correlational analysis indicated that each of the individual lifestyle factors—education, occupational complexity and activities in young adulthood, mid-life and later life—and the combined cognitive lifestyle score was positively associated with each other and negatively with depressive symptoms, while all except education were negatively associated with depressive thoughts. Depressive thoughts and symptoms were strongly correlated. Cognitive lifestyle score explained 4.6 % of the variance in depressive thoughts and 10.2 % of the variance in depressive symptoms. The association of greater participation in cognitive activities, especially in later life, with fewer depressive symptoms and thoughts suggests that preventive interventions aimed at increasing participation in cognitively stimulating leisure activity could be beneficial in decreasing the risk of experiencing depressive thoughts and symptoms in later life.

Abstract
PURPOSE Alcohol use is more prevalent in rural than urban areas in adult populations. Few studies have focused on adolescent drinking. This study investigated if adolescents in regional and rural areas of Australia were more likely to drink alcohol and if there were differences in parental drinking and alcohol supply across regions. METHODS A subsample from the National Drug Strategy Household Survey 2013, the largest nationally representative household survey on drug use in Australia, was used for this study. Participants who were aged 12-17 (N = 1,159) and participants who indicated they were parents or guardians of a dependent child (N = 7,059) were included in the analyses. Key measures were adolescent and parental alcohol use, parental supply of alcohol, and drinking location. FINDINGS Compared to those living in major cities, adolescents from inner regional and rural areas were at 85% and 121% higher odds, respectively, of obtaining their first alcohol from parents, and at 131% and 287% higher odds of currently obtaining their alcohol from their parents. Those from rural areas were at 126% higher odds of drinking in the past 12 months. Parents from inner regional and rural areas were at 45% and 63% higher odds, respectively, of heavy drinking; at 27% and 52% higher odds of weekly drinking; and at 26% and 37% higher odds of drinking at home. CONCLUSIONS Adolescents from rural areas were at higher risk of alcohol use. Parents in rural areas were more likely to use alcohol in ways that encourage adolescent drinking.

Using realist review to inform intervention development: methodological illustration and conceptual platform for collaborative care in offender mental health. Implement Sci 2015; 10:134.

Abstract
BACKGROUND This paper reports how we used a realist review, as part of a wider project to improve collaborative mental health care for prisoners with common mental health problems, to develop a conceptual platform. The importance of offenders gaining support for their mental health, and the need for practitioners across the health service, the criminal justice system, and the third sector to work together to achieve this is recognised internationally. However, the literature does not provide coherent analyses of how these ambitions can be achieved. This paper demonstrates how a realist review can be applied to inform complex intervention development that spans different locations, organisations, professions, and care sectors. METHODS We applied and developed a realist review for the purposes of intervention development, using a three-stage process. (1) An iterative database search strategy (extending beyond criminal justice and offender health) and groups of academics, practitioners, and people with lived experience were used to identify explanatory accounts (n = 347). (2) From these accounts, we developed consolidated explanatory accounts (n = 75). (3) The identified interactions between practitioners and offenders (within their organisational, social, and cultural contexts) were specified in a conceptual platform. We also specify, step by step, how these explanatory accounts were documented, consolidated, and built into a conceptual platform. This addresses an important methodological gap for social scientists and intervention developers about how to develop and articulate programme and implementation theory underpinning complex interventions. RESULTS An integrated person-centred system is proposed to improve collaborative mental health care for offenders with common mental health problems (near to and after release) by achieving consistency between the goals of different sectors and practitioners, enabling practitioners to apply scientific and experiential knowledge in working judiciously and reflectively, and building systems and aligning resources that are centred on offenders' health and social care needs. CONCLUSIONS As part of a broader programme of work, a realist review can make an important contribution to the specification of theoretically informed interventions that have the potential to improve health outcomes. Our conceptual platform has potential application in related systems of health and social care where integrated, and person-centred care is a goal.

Abstract
BACKGROUND An association between interval breast cancers (cancer detected after a normal mammogram and before the next scheduled mammogram) and tumour aggressiveness has been postulated which may reflect their relatively poor overall prognosis. The aim of this study was to evaluate known prognostic features of screen detected breast cancers compared to interval breast cancers. METHODS Patients diagnosed with breast cancer between January 2010 and 2013 at a single unit of the National Breast Screening Program (NBSP) in Ireland and those between the ages of 50 and 65 diagnosed at a symptomatic breast clinic were included in the study. Patients who had not had a screening mammogram within the proceeding two years or had a previous history of breast cancer were excluded. Data were retrospectively collected on patient demographics, tumour type, grade, hormone receptor status and stage of disease at presentation. RESULTS There were 915 patients included in the study, with 92% (n = 844) diagnosed through the NBSP. Ductal carcinoma in-situ accounted for 19% (n = 160) of screen-detected breast cancers but only 2.8% of interval cancers (p < 0.05). The most common type of invasive cancer was invasive ductal carcinoma. Tumour grade was significantly higher in interval breast cancers (p < 0.05). Interval cancers were identified at a significantly higher stage (Stage 1 versus 2; p < 0.001) than screen-detected cancers. Interval breast cancers were less likely to be ER positive (76% versus 81%; p < 0.05) and significantly more likely to over-express HER2 (20% vs 10%, p < 0.05) than screen-detected cancers. CONCLUSION This study highlights the fact that interval cancers appear to have a number of adverse prognostic markers for overall breast cancer survival when compared to women with screen-detected breast cancers. Interval cancers were more likely to be invasive, of a higher grade and stage and with a greater predominance of HER2 and triple negative molecular subtypes. Therefore this heterogeneous group of tumours may be biologically more aggressive and account disproportionately to overall breast cancer mortality.

Abstract
Fucoidans are complex sulfated polysaccharides extracted from brown algae. Depending on the concentration, they have been shown to stimulate and inhibit blood coagulation in vitro. Promotion of coagulation is mediated by blocking tissue factor pathway inhibitor (TFPI). We screened fucoidan extracts from four brown algae species in vitro with respect to their potential to improve coagulation in bleeding disorders. The fucoidans' pro- and anticoagulant activities were assessed by global hemostatic and standard clotting assays. Results showed that fucoidans improved coagulation parameters. Some fucoidans also activated the contact pathway of coagulation, an undesired property reported for sulfated glycosaminoglycans. Chemical evaluation of fucoidans' complex and variable structure included molecular weight (Mw), polydispersity (polyD), structural heterogeneity, and organic and inorganic impurities. Herewith, we describe a screening strategy that facilitates the identification of crude fucoidan extracts with desired biological and structural properties for improvement of compromised coagulation like in hemophilia.

Abstract
Self-management offers a way of helping people with dementia or mild cognitive impairment (MCI) to play an active role in managing their condition. Barlow, Wright, Sheasby, Turner, and Hainsworth have defined self-management as the "individual's ability to manage the symptoms, treatment, physical and psychosocial consequences and life style changes inherent in living with a chronic condition." Although commonly used in other chronic health conditions, there has been relatively little exploration of the role of self-management in dementia or MCI. This review aimed to identify group-based psychosocial interventions for people with dementia or MCI that incorporate significant elements of self-management. Fifteen interventions were included in the review: 12 for people with dementia and 3 for participants with MCI. In both the dementia and MCI interventions, the most commonly included self-management components were information, communication, and social support, and skills training. The review findings indicate that components of self-management have been incorporated into group-based interventions for people with dementia and MCI. Further studies are needed to address the methodological limitations of the included studies and to determine the effectiveness of self-management interventions with these populations.

Abstract
AIMS Methamphetamine-related harms in Victoria have increased recently in the context of stable or declining use prevalence. We determine how changes in price and purity of methamphetamine compared to other drugs such as heroin may, in part, explain these divergent patterns. METHODS Detailed methamphetamine and heroin purchase price data from 2152 participant interviews from the Melbourne Injecting Drug User cohort study were used to generate drug price series for the period January 2009-June 2013. Data on drug purity from 8818 seizures made within Victoria were used to generate drug purity series during the same period. Purity-adjusted price data for methamphetamine and heroin were obtained for the period 2009-13 by combining the two data sets. RESULTS While the average purity of heroin seizures remained consistent and low, the average purity of powder and of crystal methamphetamine seizures increased from 12% [95% confidence interval (CI) = 10-14%] to 37% (95% CI = 20-54%) and 21% (95% CI = 18-23%) to 64% (95% CI = 60-68%), respectively. Crystal methamphetamine purity was bimodal, with observations generally less than 20% or greater than 70%. The average unadjusted price per gram for heroin decreased from $374 (95% CI = $367-381) to $294 (95% CI = $280-308), powder methamphetamine did not change significantly from $252 (95% CI = $233-271), and crystal methamphetamine increased substantially from $464 (95% CI = $416-511) in 2009 to $795 (95% CI = $737-853) in 2011. This increase was offset by an even greater increase in purity, meaning the average purity-adjusted price per gram declined. Furthermore, pure prices of both methamphetamine forms were similar, whereas their unadjusted prices were not. The pure price of heroin fluctuated with no ongoing trends. CONCLUSIONS Decreases in methamphetamine purity-adjusted price along with the bimodality of crystal methamphetamine purity may account for some of the recent increase in methamphetamine-related harm. For a given amount spent, methamphetamine purchase power has increased and the presence of extreme purity variations may challenge individuals' control of consumption.
