Background: Awareness and understanding of dementia remain limited in ethnically diverse populations in multicultural societies due to culturally inappropriate and inaccessible information. Objective: To establish the impact, helpers and hinderers of an online multilingual dementia awareness initiative co‐created with and for English, Arabic and Vietnamese speaking people. Design: A case study using mixed methods to assess the impact and implementation of an information session on dementia knowledge. Setting and Participants: The study was conducted with English, Arabic and Vietnamese speaking individuals in Canterbury‐Bankstown, Australia. Intervention Studied: A dementia alliance co‐created an online multilingual dementia information session, which was delivered synchronously in English, Arabic and Vietnamese by trained facilitators. Main Outcome Measures: In‐session group discussions, quizzes and a postsession survey assessed the impact on dementia knowledge. A postimplementation focus group explored the factors that helped and hindered the initiative. Results: The online dementia information session successfully supported participants understanding of dementia causes, impacts and care strategies. The initiative was hindered by competing priorities and limited accessibility to target audiences, while it was helped by the support of an established organisation and feedback mechanisms. Discussion: Ongoing dementia education and awareness‐raising campaigns that are culturally sensitive are needed in communities to promote dementia literacy and help‐seeking. Conclusions: An online multilingual dementia information session can be an effective way to improve dementia literacy and advocate for change in multicultural communities. Patient or Public Contribution: English, Arabic and Vietnamese speaking members of the Canterbury Bankstown Dementia Alliance participated in the co‐creation and evaluation of this initiative.

Background: Communities that do not accommodate the needs and preferences of people with dementia can exacerbate disability and isolation. Although dementia‐friendly communities (DFCs) were established to foster understanding and acceptance of dementia, the built environment remains underexplored. We identified the challenges and opportunities for fostering dementia‐enabling environments among community planners. Method: This study is set in South‐West Sydney, Australia, where a DFC is being established. The policies of seven local governments were analysed for actions that aligned with Dementia Australia's 41 DFC recommendations: 13 for social, 14 for outdoor, and 14 for indoor environments. An online workshop was then held with 30 community planners to raise awareness for dementia‐enabling environments. Participants were surveyed about their dementia beliefs and attitudes. Facilitated discussions identified challenges and opportunities for designing DFCs. Qualitative and quantitative data across all sources were triangulated. Result: Although none of the local government policies specifically mentioned dementia, up to 20/41 DFC actions were met. Most of these were in social engagement (with ≤10/13 recommendations met by each local government). Less action was taken on outdoor and indoor environments (with ≤9/14 outdoor and ≤4/14 indoor recommendations met by up to six local governments). Although beliefs and attitudes about dementia among planners were generally positive, only 48% indicated that they had a good understanding of it and nearly 80% noted they would feel anxious and depressed about a diagnosis. Key DFC challenges included a lack of awareness and conflicting priorities between government bodies. Opportunities included engaging with universities to conduct demographically relevant awareness raising, facilitate multisectoral collaboration, developing an evidence‐base, and involving service providers to engage with the dementia community. Conclusion: This study triangulated data to identify gaps in community planning efforts, confirming that more action is required to design dementia‐friendly communities. We are now leading a multisectoral collaboration to educate community planners and the public, and are advocating for the recognition of dementia‐friendly environments in government plans. This study provides practical guidance to assist planners with DFC designs. [ABSTRACT FROM AUTHOR]

Background and Aims: Accurate biomarkers to predict outcomes following discontinuation of nucleos(t)ide analogue (NA) therapy are needed. We evaluated serum hepatitis B core-related antigen (HBcrAg) level as a biomarker for predicting outcomes after NA discontinuation., Methods: Patients with HBeAg-negative chronic hepatitis B (CHB) without cirrhosis were enrolled in a prospective trial evaluating clinical outcomes until 96 weeks after NA discontinuation. End of treatment (EOT) and off-treatment levels of serum HBcrAg, HBsAg, HBV RNA and HBV DNA were used to predict key clinical outcomes including hepatitis flare (ALT ≥5 × ULN and HBV DNA > 2000 IU/mL). The SCALE-B score was calculated for the purposes of model validation., Results: HBcrAg was tested amongst 65 participants. The median age was 54 years, 54% were male and 83% were Asian. HBcrAg was detectable in 86% patients. HBcrAg level ≥4 log U/mL at EOT was predictive of hepatitis flare [8/10 (80%) vs. 17/55 (31%), p = .001]. The presence of either HBcrAg ≥4 log U/mL or detectable HBV RNA at EOT predicted for both biochemical relapse and hepatitis flare. The SCALE-B model at EOT predicted for virological relapse, biochemical relapse, hepatitis flare and HBsAg loss in this cohort. An increase in the serum HBcrAg level off-treatment was also associated with hepatitis flare. No participant with EOT HBcrAg level ≥4 log U/mL achieved HBsAg loss., Conclusions: High levels of serum HBcrAg predict for hepatitis flare after stopping NA therapy and low likelihood of HBsAg loss at week 96. People with high levels of serum HBcrAg are not suitable candidates for NA discontinuation., (© 2024 The Author(s). Liver International published by John Wiley & Sons Ltd.)

Objective: To identify factors associated with neonatal respiratory distress (NRD) in early Gestational diabetes mellitus (eGDM)., Design: Nested case-control analysis of the TOBOGM trial., Setting: Seventeen hospitals: Australia, Sweden, Austria and India., Population: Pregnant women, <20 weeks' gestation, singleton, GDM risk factors., Methods: Women with GDM risk factors completed an oral glucose tolerance test (OGTT) before 20 weeks: those with eGDM (WHO-2013 criteria) were randomised to immediate or deferred GDM treatment. Logistic regression compared pregnancies with/without NRD, and in pregnancies with NRD, those with/without high-dependency nursery admission for ≤24 h with those admitted for >24 h. Comparisons were adjusted for age, pre-pregnancy body mass index, ethnicity, smoking, primigravity, education and site. Adjusted odds ratios (95% CI) are reported., Main Outcome Measures: NRD definition: ≥4 h of respiratory support (supplemental oxygen or supported ventilation) postpartum. Respiratory distress syndrome (RDS): Supported ventilation and ≥24 h nursery stay., Results: Ninety-nine (12.5%) of 793 infants had NRD; incidence halved (0.50, 0.31-0.79) if GDM treatment was started early. NRD was associated with Caesarean section (2.31, 1.42-3.76), large for gestational age (LGA) (1.83, 1.09-3.08) and shorter gestation (0.95, 0.93-0.97 per day longer). Among NRD infants, >24 h nursery-stay was associated with higher OGTT 1-h glucose (1.38, 1.08-1.76 per mmol/L). Fifteen (2.0%) infants had RDS., Conclusions: Identifying and treating eGDM reduces NRD risk. NRD is more likely with Caesarean section, LGA and shorter gestation. Further studies are needed to understand the mechanisms behind this eGDM complication and any long-term effects., (© 2024 The Author(s).

Introduction: Hepatitis C virus (HCV) prevalence is high in the mental health population. We sought to evaluate testing and treatment uptake for HCV following the implementation of a universal nurse led study in inpatient and outpatient mental health populations., Methods: From January 2018 to December 2020, we screened mental health inpatients (n = 322) and community mental health patients (n = 615) for HCV with either specialist hepatology nurses or mental health nurses (mental health nurse)., Results: 75.5% (464/615) of community patients and 100% (322/322) of inpatients consented to screening, with an HCV antibody-positive prevalence of 12.7% (59/464) in community patients and 19.6% (63/322) in inpatients. RNA detectable prevalence was 4.0% (22/464) and 7.5% (24/322), respectively. Community patients who were screened by specialist hepatology nurses were more likely to consent to screening (94.4% vs. 45.7%, p < 0.001) but had lower proportion of HCV antibody (10.5% vs. 20.3%, p < 0.001) and RNA detectable (4.0% vs. 7.5%, p = 0.018) when compared to mental health nurse screening. Engagement with treatment was 27.0% of community mental health patients and 45.8% of mental health inpatients undergoing treatment. All patients undergoing treatment and underwent sustained viral response (SVR) testing achieved SVR., Discussion and Conclusions: Universal screening of HCV using a nurse-led model has high rates of success in mental health patients with high proportions undergoing screening, with no reduction in the rates of SVR achieved with DAA therapy compared to the general population. Further work is needed to bridge the gap between identification of HCV and treatment among mental health patients., (© 2024 Australasian Professional Society on Alcohol and other Drugs.)

Background: Delirium is an acute disorder of attention and cognition with an incidence of up to 70% in the adult intensive care setting. Due to the association with significantly increased morbidity and mortality, it is important to identify who is at the greatest risk of an acute episode of delirium while being cared for in the intensive care. The objective of this study was to determine the ability of the cumulative deficit frailty index and clinical frailty scale to predict an acute episode of delirium among adults admitted to the intensive care., Methods: This study is a secondary analysis of the Deli intervention study, a hybrid stepped-wedge cluster randomized controlled trial to assess the effectiveness of a nurse-led intervention to reduce the incidence and duration of delirium among adults admitted to the four adult intensive care units in the south-west of Sydney, Australia. Important predictors of delirium were identified using a bootstrap approach and the absolute risks, based on the cumulative deficit frailty index and the clinical frailty scale are presented., Results: During the 10-mth data collection period (May 2019 and February 2020) 2566 patients were included in the study. Both the cumulative deficit frailty index and the clinical frailty scale on admission, plus age, sex, and APACHE III (AP III) score were able to discriminate between patients who did and did not experience an acute episode of delirium while in the intensive care, with AUC of 0.701 and 0.703 (moderate discriminatory ability), respectively. The addition of a frailty index to a prediction model based on age, sex, and APACHE III score, resulted in net reclassified of risk. Nomograms to individualize the absolute risk of delirium using these predictors are also presented., Conclusion: We have been able to show that both the cumulative deficits frailty index and clinical frailty scale predict an acute episode of delirium among adults admitted to intensive care., (© 2023 The Authors.

Early and intensive management of type 2 diabetes has been shown to delay disease progression, reduce the risk of cardiorenal complications and prolong time to treatment failure. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are being increasingly recognized for their potential in early disease management, with recent guideline updates recommending second-line use of this injectable drug class alongside oral glucose-lowering drugs. GLP-1RAs target at least six of the eight core defects implicated in the pathogenesis of type 2 diabetes and offer significant glycaemic and weight-related improvements over other second-line agents in head-to-head trials. In addition, placebo-controlled clinical trials have shown cardiovascular protection with GLP-1RA use. Even so, this therapeutic class is underused in primary care, largely owing to clinical inertia and patient-related barriers to early intensification with GLP-1RAs. Fortunately, clinicians can overcome barriers to treatment acceptance through patient education and training, and management of treatment expectations. In this review we comment on global and Australian guideline updates and evidence in support of early intensification with this therapeutic class, and provide clinicians with practical advice for GLP-1RA use in primary care., (© 2022 The Authors.

Background and Aims: Achieving Hepatitis B e antigen seroconversion (HBeAg SC) at an earlier age confers a better prognosis. We examined baseline and post-partum factors associated with HBeAg SC after pregnancy. We developed a tool, the SydPregScore, to estimate the likelihood of HBeAg SC in the years after pregnancy., Methods: A retrospective analysis of an HBeAg-positive pregnant cohort was conducted. Variables including baseline age, parity, alanine aminotransferase level, HBV viral load, quantitative HBsAg, use of antiviral therapy and post-partum flare were collected. Univariate and multivariate Cox regression analyses to determine predictors of HBeAg SC and develop a predictor score were performed., Results: We analysed HBeAg SC rates in 220 pregnancies to 149 HBeAg-positive women from 2006 to 2019. At baseline, their median age was 33 (IQR 29-37), ALT 23 U/L (IQR 17-33) and viral load 8 log 10 IU/mL (IQR 6.3-8.2 log 10 IU/mL). The majority (133/198, 67.2%) received short-course antiviral therapy to prevent mother-to-child transmission, and 109/192 (56.8%) had a post-partum flare. HBeAg SC occurred in 74/220 (33.6%) after pregnancy (median follow-up 814 days, IQR 405-1531). Multivariate analysis identified baseline viral load <8 log 10 IU/mL (HR 2.426 [1.224-4.809], p = .011), baseline ALT ≥2 ULN (HR 2.726 [1.299-5.721], p = .008) and age <35 (HR 2.859 [1.255-6.513], p = .012) to be positive predictors of HBeAg SC. The 'SydPreg Score' estimated the probability of HBeAg SC at 2000 days as 10%, 30%, 70% and 80% for 0, 1, 2, and 3 predictors respectively., Conclusion: The SydPreg Score allows the prediction of HBeAg SC in the years after pregnancy. Even in those without elevated ALT, age <35 and viral load <8 log 10 IU/mL can identify women with a good chance of subsequent HBeAg SC. Those without a chance may benefit from viral suppression., (© 2022 The Authors. Liver International published by John Wiley & Sons Ltd.)

Rationale, Aims and Objective: Details of the development and implementation of integrated care pathways (ICPs) in the context of electronic collection of patient reported outcomes (ePROs) for cancer patients are largely lacking in the literature. This study describes what, why and how decisions were made to adapt and implement an ePROs ICP for patients with lung cancer., Methods: A consensus process was utilized, with the implementation advisory group including multidisciplinary representation from three participating hospitals, to identify local champions and adapt and incorporate the ePRO ICP into the local contexts. Engagement meetings were documented via meeting transcripts, and detailed notes from October 2019 to November 2020 were content-analysed to identify decision-making themes based on the Consolidated Framework for Implementation Research; workflows and process maps were reviewed and modified to integrate ePROs., Results: In total, 55 engagement activities were held (24 meetings, 20 workshops 11 educational sessions), with n = 96 staff from multiple disciplines participating in the ePROs implementation through advisory meetings, process mapping, change management and staff education. Decisions were made regarding eligible patient cohorts to include, the process for onboarding patients onto the ePRO system, and follow-up and referral pathways. Rationales for decisions included alignment with existing workflows, utilizing available staff, minimizing staff and patient burden and maximizing patient engagement., Conclusion: Existing resources, staff input and technical and logistical reasons often guided the ICP decisions, highlighting the need for in-depth engagement across all stakeholders for optimal implementation of ePRO ICPs. The ePRO implementation required substantial dialogue and systematic resolution to reach agreement on the final processes. Adapting the local ICP through rigorous engagement facilitated the successful implementation of ePROs as business-as-usual at all three cancer centres. Involving all relevant stakeholders is critical to the successful adaptation of ICPs before their introduction into routine care., (© 2022 John Wiley & Sons Ltd.)

Background and Aims: Current guidelines recommend long-term nucleot(s)ide analogue (NA) therapy for patients with HBeAg-negative chronic hepatitis B (CHB). However, disease remission has been described after stopping NA therapy, as well as HBsAg loss., Methods: We performed a prospective multi-centre cohort study of stopping NA therapy. Inclusion criteria were HBeAg-negative CHB, the absence of cirrhosis and HBVDNA5× ULN occurred in 35 (32%); ALT flares were not associated with HBsAg loss. There were no unexpected safety issues., Conclusion: Virological reactivation was very common after stopping NA therapy and occurred earlier after stopping TDF versus ETV. The majority of patients had ALT <2× ULN at week 96, but only one-third achieved disease remission and HBsAg loss was rare. Very low HBsAg levels at baseline were uncommon but predicted for HBsAg loss and disease remission., (© 2022 John Wiley & Sons Ltd.)

Psychological interventions may be effective in improving adherence after bariatric surgery; however, there is limited research on patients' willingness to engage with psychological aftercare. This study aimed to qualitatively explore patient perspectives on psychological services in the bariatric setting. Participants reported believing that psychological care is essential for treatment success and indicated that they wanted support with adjusting to changes in lifestyle, self-identity, and relationships after surgery. Participants suggested that psychological aftercare should be recommended by their medical team and incorporated into standard management after bariatric surgery. These findings can be used to inform the design of services for bariatric surgery patients., (© 2020 World Obesity Federation.)

The balance between avoiding severe acute respiratory syndrome coronavirus-2 contagion and reducing wider clinical risk is unclear for gestational diabetes mellitus (GDM) testing. Recent recommendations promote diagnostic approaches that limit collection but increase undiagnosed GDM, which potentially increases adverse pregnancy outcome risks. The most sensitive approach to detecting GDM at 24-28 weeks beyond the two-hour oral glucose tolerance test (OGTT) is a one-hour OGTT (88% sensitivity). Less sensitive approaches use fasting glucose alone (≥5.1 mmol/L: misses 44-54% GDM) or asking ~20% of women for a second visit (fasting glucose 4.7-5.0 mmol/L (62-72% sensitive)). Choices should emphasise local and patient decision-making., (© 2020 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

Background: Gestational diabetes (GDM) is one of the commonest pregnancy complications and is placing an increasing burden on diabetes and obstetric resources., Aims: To describe different antenatal models of care that have developed to address the increasing proportion of pregnancies complicated by GDM., Materials and Methods: Narrative review with thematic analysis from 15 volunteer antenatal diabetes in pregnancy services from Australia and New Zealand identified through a national diabetes organisation. Main outcomes were approaches to patient education, medical nutrition therapy (MNT), ongoing management and escalation of therapy for women with GDM., Results: All clinics provided at least one group education and one MNT session within 1-2 weeks of GDM diagnosis. Women from culturally and linguistically diverse communities usually required 1:1 education. Ongoing management of women with GDM was through either all women being seen in the GDM clinic, a step-up approach (ongoing management by the primary antenatal team with diabetes team referral if self-blood glucose monitoring (SBGM) or insulin therapy dosage criteria are reached) or step-down approach (ongoing management by the diabetes team with step-down to the primary antenatal team if SBGM criteria are reached). Telehealth was used to reduce the burden of clinic attendance, particularly in rural areas., Conclusions: Increasing numbers, earlier diagnoses, the need to provide care to women in rural, remote areas, and cultural/language differences, have generated a range of different antenatal models of care, allowed better workload accommodation and probably reduced costs. Randomised controlled trials of different models of care, with associated health economic analyses, are urgently needed., (© 2020 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

Background Programs targeting the standard modifiable cardiovascular risk factors (SMuRFs: hypertension, diabetes mellitus, hypercholesterolemia, smoking) are critical to tackling coronary heart disease at a community level. However, myocardial infarction in SMuRF-less individuals is not uncommon. This study uses 2 sequential large, multicenter registries to examine the proportion and outcomes of SMuRF-less ST-segment-elevation myocardial infarction (STEMI) patients. Methods and Results We identified 3081 STEMI patients without a prior history of cardiovascular disease in the Australian GRACE (Global Registry of Acute Coronary Events) and CONCORDANCE (Cooperative National Registry of Acute Coronary Syndrome Care) registries, encompassing 42 hospitals, between 1999 and 2017. We examined the proportion that were SMuRF-less as well as outcomes. The primary outcome was in-hospital mortality, and the secondary outcome was major adverse cardiovascular events (death, myocardial infarction, or heart failure, during the index admission). Multivariate regression models were used to identify predictors of major adverse cardiovascular events. Of STEMI patients without a prior history of cardiovascular disease 19% also had no history of SMuRFs. This proportion increased from 14% to 23% during the study period ( P =0.0067). SMuRF-less individuals had a higher in-hospital mortality rate than individuals with 1 or more SMuRFs. There were no clinically significant differences in major adverse cardiovascular events at 6 months between the 2 groups. Conclusions A substantial and increasing proportion of STEMI presentations occur independently of SMuRFs. Discovery of new markers and mechanisms of disease beyond standard risk factors may facilitate novel preventative strategies. Studies to assess longer-term outcomes of SMuRF-less STEMI patients are warranted.

Background & Aims: Antipartum antiviral therapy in the setting of high viral load is recommended to prevent mother-to-child transmission of hepatitis B although recommended viral load cut-offs vary. Quantitative HBsAg has been proposed as an alternative screening strategy to identify high viral load in this setting. Guidelines suggest testing all infants for vaccine response and infection. We set out to re-examine viral load cut-offs; the predictive value of quantitative HBsAg and the need for follow-up infant testing in our cohort., Methods: A retrospective cohort study of 469 HBsAg positive mother-baby pairs from 2 tertiary hospitals in Sydney was performed. Antiviral therapy (lamivudine or tenofovir disoproxil fumarate) was offered to women with viral load ≥6 log 10  IU/mL (high) from 32 weeks gestation. Transmission and vaccine response was analysed according to viral load. The utility of quantitative HBsAg in identifying high viral load was examined., Results: Mother-to-child transmission only occurred in setting of high viral load, in 0.85% (1/117) of those who received antiviral therapy and in 8.66% (2/23) of those who chose not to. Quantitative HBsAg did not accurately identify high-risk mothers HBV DNA ≥6 log 10  IU/mL. Successful infant vaccine response was 98.7% overall, and 99.4% when viral load was <6 log 10  IU/mL., Conclusion: Antiviral therapy initiated at 32 weeks when maternal viral load is ≥6 log 10  IU/mL almost completely abrogates transmission. Quantitative HBsAg does not reliably predict high viral load. When maternal viral load is <6 log 10  IU/mL, high vaccine efficacy and zero transmission suggests testing infants is of little value., (© 2018 John Wiley & Sons A/S.

The most recent hypothesis of the development of small vessel vascular dementia (VaD) emphasises the role of blood-brain barrier (BBB) dysfunction. It is hypothesised that certain genetic polymorphisms of the BBB tight junction claudin-1 protein, in combination with adverse environmental risk factors, increase the risk of BBB dysfunction and small vessel VaD. In this case-control study, 97 control participants, with a mean Mini Mental State Exam (MMSE) score of 29.1, and 38 VaD participants were recruited and completed a questionnaire on their medical history and lifestyle factors. Blood was also collected and two single nucleotide polymorphisms (SNPs), rs17501010 and rs893051 of claudin-1 genotyping, were analysed by real-time polymerase chain reaction (PCR) assay. A significantly higher frequency of all rs893051 SNP genotypes (GC and CC) was found in the VaD population (OR=4.8, P=0.006 and OR=6, P<0.001 respectively). Patients with TT genotype of rs17501010 were also more likely to have VaD (OR=3.25, P=0.022). Stratification analysis revealed that having combined haplotype GC+CC of rs893051 and lipid disorders was associated with higher risk of VaD (OR=9.9, P<0.001). For patients with type 2 diabetes the odds ratio of VaD increased significantly in GC+CC genotypes of rs893051 (OR=12.57, P<0.0001) and GT+TT of rs17501010 (OR=5.33, P=0.01)., (© 2017 John Wiley & Sons Australia, Ltd.)

Objectives: Episodic foresight refers to the capacity to mentally travel forward in time and has been linked to a wide variety of important functional behaviours. Evidence has recently emerged that chronic opiate use is associated with deficits in this critical capacity and that these difficulties are not simply a secondary consequence of broader cognitive dysfunction. The current study aimed to better understand the circumstances in which chronic opiate users might be expected to have problems with episodic foresight, by addressing whether deficits reflect compromised scene construction, self-projection, or narrative ability., Methods: Thirty-five chronic opiate users and 35 demographically matched controls completed an imagination task in which they were instructed to imagine and provide descriptions of an atemporal event, a plausible, self-relevant future event, as well as complete a narrative task. These three imagination conditions systematically varied in their demands on scene construction, self-projection, and narrative ability., Results: Consistent with prior literature, chronic opiate users exhibited reduced capacity for episodic foresight relative to controls. However, this study was the first to show that these difficulties were independent of capacity for scene construction and narration. Instead, a specific impairment in self-projection into the future appears to contribute to the problems with episodic foresight seen in this clinical group., Conclusions: Deficits in self-projection into the future may have important implications in therapeutic environments given that many relapse prevention strategies rely heavily on the ability to project oneself into an unfamiliar future, free of problem substance use., Practitioner Points: A reduced capacity for episodic foresight highlights the importance of refining current relapse prevention protocols that place significant demands for mental time travel into the future. Psychosocial treatments should focus on the attainment of more immediate or short-term goals. It is difficult to delineate the effects of specific substances given long-standing drug use history common to chronic opiate users. Conclusions relating to neurological functioning are speculative given the absence of neuroimaging data., (© 2016 The British Psychological Society.)

We surveyed members of National Association of Diabetes Centres (NADC) assessing use of new Australasian Diabetes In Pregnancy Society (ADIPS) and Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) Gestational Diabetes Mellitus (GDM) diagnostic guidelines in Australia. We found piecemeal adoption of recommended changes, with cessation of the 50 g glucose challenge test (GCT) universal, early screening implementation common, but by varied methodologies, and new diagnostic criteria acceptance far from complete with significant workload increases almost universal., (© 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

Vascular dementia (VaD) describes a combination of both cognitive and behavioural manifestations associated with variable brain lesions of vascular origin. While vascular risk factors have been implicated in VaD, the relationship is most evident when the factors are considered together and not individually. This review will examine the significance of the integrity of blood brain barrier (BBB) tight junction (TJ) proteins - occludin and claudins in the pathophysiology of VaD. Specifically, some of the genetic contributors to VaD, namely those responsible for the integrity of the BBB, will be reviewed in detail. Moreover, environmental factors will be considered in conjunction with these genes to examine how the interaction of environmental and genetic factors contributes to one's susceptibility to VaD., (© 2016 John Wiley & Sons Australia, Ltd.)

Objective: To evaluate the efficacy of intensive lipid lowering with higher-dose statins., Methods: Meta-analysis of seven randomized controlled trials comprising 50,972 participants., Results: Mean follow-up was 3.1 years with mean age 63 years. Final LDL-C levels in intensive lipid-lowering group were 1.42-2.07 mmol/l compared to 2.1-3.5 mmol/l in the less intensive or control group. The intensive arm had significantly lower risks for stroke OR 0.80 (95% CI 0.71-0.89); major coronary events OR 0.74 (95% CI 0.65-0.83); cardiovascular disease (CVD) or coronary heart disease (CHD) deaths OR 0.84 (95% CI 0.74-0.95). Significantly higher liver enzyme abnormalities occurred in intensive group* (OR 3.96; 95% CI 2.08-7.53), but it was not associated with drug discontinuations (OR 1.20; 95% CI 0.88-1.64)., Conclusion: In those at high risk of cardiovascular events, intensive lipid lowering with statins to LDL-C level <2.1 mmol/l significantly reduces risk of stroke, major coronary events and CVD or CHD deaths compared to LDL-C level ≥ 2.1 mmol/l.

Background: Gestational diabetes mellitus (GDM) is recognised as a significant problem in pregnancy. Changes to GDM diagnostic criteria have been proposed following analysis of data from the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study. We sought to assess the impact on the workload for GDM management in Australia that would occur if these changes were adopted., Aim: To assess the impact on health professional workload, specifically management of the number of additional women who would be diagnosed with GDM, should the newly recommended diagnostic criteria be adopted in Australia., Methods: We analysed oral glucose tolerance test results undertaken in pregnant women at two large pathology services in South West and Northern Sydney. We calculated GDM rates using current Australasian Diabetes in Pregnancy Society (ADIPS) Australian Criteria and the rates using the proposed new criteria., Results: These workload data compare ADIPS and proposed International Association of Diabetes and Pregnancy Study Groups Criteria. In a high-risk population examined in two time periods, the estimated increase in workload was 29.0% (based on November 2005 to August 2007 data) and 31.9% (based on September 2007 to August 2009 data). Data from Northern Sydney indicated a 21.7% increased workload (based on September 1998 to July 2009 data)., Conclusions: If the newly recommended changes to the diagnostic criteria for GDM are implemented in Australia, we may need to change the way we currently structure our services to manage GDM, to cope with the workload impact of the significantly increased number of women who would require management. In some units this change will be substantial., (© 2010 The Authors.

STUDY OBJECTIVE - Nested case-control study aimed to assess the quality of life of community dwelling participants aged 65 years or over with newly diagnosed Essential Tremor (ET). METHODS AND RESULTS - Thirty-two participants with newly diagnosed ET and 32 age and gender matched controls were administered the Rand-SF36 quality of life questionnaire. Medical co-morbidities were also assessed in the two groups. Results - Participants with ET had significantly lower scores in the physical function, role limitation because of physical function, role limitation as a result of emotional problem, pain, and energy/vitality subscales of the Rand-SF36 when compared with controls. CONCLUSIONS - Older patients with newly diagnosed ET have poorer quality of life than their community dwelling counterparts without ET.

Objective: To investigate risk factors, stroke pattern and outcome in stroke patients with cancer., Methods: A retrospective review of all stroke patients with cancer (n = 69) admitted to Bankstown-Lidcombe Hospital, Sydney, Australia, between January 1999 and December 2004 was conducted, and comparison made to age- and gender-matched non-cancer stroke patients admitted to the same hospital during the same period., Results: Vascular risk factors did not significantly differ between cancer and non-cancer groups. There was a trend towards greater risk of intracerebral haemorrhage in the cancer group vs the non-cancer group. Previous deep vein thrombosis was more common, and prothrombin time and activated partial thromboplastin time were prolonged in the cancer group vs the non-cancer group. More patients died in hospital in the cancer group vs the non-cancer group., Conclusions: Coagulation disorders are more likely to be seen in stroke patients with cancer, and patients with cancer have a higher in-hospital post-stroke mortality.

Objectives: To examine 12-month outcomes and develop predictive models for outcomes in elderly stroke patients., Methods: Prospective study of 186 consecutive acute stroke patients aged > or = 65 years admitted to a local hospital between March 2002 and March 2003. Outcome measurements included mortality, functional independence measure (FIM) score and nursing home placement. Two predictive models, using multiple logistic regression analysis, were developed to identify the factors associated with (i) mortality, and (ii) being alive and independent (defined as mean FIM score > or = 90) at 12 months., Results: One hundred and seventy two (92%) patients were followed up at 12 months post-stroke. Mortality rate was 31%, and was significantly higher in nursing home vs non-nursing home origin patients (68% [15/22] vs 25% [38/150]). Nursing home placement for non-nursing home origin survivors was 28% (31/112). Age > or = 85 years was associated with higher mortality (odds ratio = 5.3, 95% confidence interval = 1.8-15, P < 0.01) and lower FIM for patients living at home pre-stroke. Predictive models showed that age, not living at home pre-stroke, pre-stroke FIM < 108, inability to walk on admission, dysphasia, visual field loss and haemorrhagic stroke were associated with worse outcome., Conclusions: Predictive models--by developing new strategies to improve outcomes through identifying treatable predictive factors--may be clinically useful in elderly stroke patients.

Objective: To examine the prevalence of Parkinson's disease (PD) in Bankstown, Sydney, using the same methodology as a previous study in Randwick, Sydney, Australia (1998-1999)., Participants and Methods: Twenty census districts (CDs) for the Bankstown local government area were randomly selected. Research personnel door-knocked every household within the CDs to locate people aged > or =55 years. A structured questionnaire (containing four screening questions for PD) was administered to those agreeing to participate. Screened positive participants were invited to come for a clinical examination. This is a continuation of the previous study and data have been combined., Results: Combining data for Bankstown and Randwick gave 1028 participants; crude prevalence, 780 per 100,000 (CI: 546-1077). In Bankstown, there were 501 participants aged > or =55 years (response rate 70%); 135 were screened positive with 101 (74.8%) agreeing to a clinical examination. The prevalence of PD in the Bankstown community was 3.4% (17 of 501) (95% CI: 1.98-5.43) for those aged > or =55 years; crude prevalence 776 per 100,000 (CI: 452-1241)., Conclusion: The combined results of two Sydney studies appear to indicate that Sydney has one of the highest prevalence estimates of PD in developed countries., (Blackwell Munksgaard 2004)

In the Dahl salt-sensitive hypertensive rat, a diet containing L-arginine, the natural substrate for nitric oxide synthase, abrogates the hypertension. We postulated that nitric oxide synthase inhibition might induce a salt-sensitive form of hypertension and that this salt sensitivity might be linked to a loss of the regulatory effect of sodium ingestion on angiotensin II (Ang II) and angiotensinogen. Male Wistar-Kyoto rats were randomised to a diet containing 0.008 %, 2.2 % or 4.4 % sodium chloride and to treatment with the NO synthase inhibitor L-NAME (10 mg kg(-1) day(-1)) in the drinking water, or drinking water alone (Controls) for 4 weeks. Blood pressure was measured by tail cuff plethysmography twice weekly. After 4 weeks, the rats were anaesthetised and truncal blood collected for determination of angiotensinogen, renin, angiotensin I (Ang I), Ang II and aldosterone concentrations as well as angiotensin-converting enzyme (ACE) activity. Systolic blood pressure increased with increasing dietary sodium intake in the L-NAME-treated rats (P < 0.05). Plasma renin and aldosterone concentrations decreased with increasing dietary sodium intake in both Control and L-NAME-treated rats. Ang I and ACE activity were unchanged by increasing dietary sodium intake. In contrast, the plasma concentration of Ang II and angiotensinogen increased with increasing dietary sodium (P < 0.05 and P < 0.005, respectively). Treatment with the Ang II receptor blocker, losartan, reversed the blood pressure increase. We conclude that treatment with L-NAME induces an increase in blood pressure that is at least in part salt sensitive. Further, the salt-sensitive component appears to be Ang II-dependent, as it was associated with increasing plasma Ang II levels and could be reversed by treatment with an Ang II receptor antagonist.

Bromocriptine (Parlodel) has attracted widespread controversy for its use for postpartum lactation suppression because of recent reports of cerebral and cardiovascular complications. This case describes a maternal death in which bromocriptine therapy may have triggered myocardial infarction in a patient with asymptomatic coronary artery disease. We suggest its use with caution, especially in patients with identifiable risk factors of coronary artery disease or arteriovascular disease.

A case is presented where spontaneous rupture of a uterine arteriovenous malformation into the peritoneal cavity presented as an acute abdomen with fetal distress in late pregnancy. This is thought to be the first reported case of its type.
