A survey of genetic and palliative care health professionals' views of integrating genetics into palliative care.

Genetic counselling and testing have utility for people with palliative care needs and their families. However, genetic and palliative care health professionals have described difficulties initiating palliative-genetic discussions. Between March and July 2022, we received n = 73 surveys (6% response rate) from genetic and palliative care health professionals in Australia and New Zealand that assessed and compared barriers and facilitators. The main perceived barrier to both groups was palliative care health professionals' lack of genetic knowledge (44%). Most palliative care health professionals were 'not at all confident' performing several activities, including discussing DNA banking (52%) and knowing their legal responsibilities when sharing genetic information (58%). The most frequently selected facilitator for genetic health professionals was fostering close relationships with palliative care health professionals (52%), while palliative care health professionals indicated a genetic referral template (51%) would be of assistance. Almost all participants agreed genetic discussions do not undermine the central ethos of palliative care (87%). Fewer palliative care health professionals considered themselves well situated to have genetic discussions with a palliative patient's family compared to genetic health professionals (p = 0.014). Our results suggest that genetic and palliative care health professionals support integrating genetics into palliative care, although refinement of the palliative care health professionals' role in this process is required. We have identified intervention targets to overcome barriers related to knowledge and confidence, which ought to be integrated into future interventions designed to support health professionals deliver the benefits of genetic information to people with palliative care needs and their families.

The incidence of falls after first and second eye cataract surgery: a longitudinal cohort study.

OBJECTIVE: To compare fall incidence, and visual acuity and refractive status, before surgery and after first and second eye cataract surgery. DESIGN, SETTING: Prospective observational study in eight tertiary referral ophthalmology clinics in public hospitals in Sydney, Melbourne, and Perth. PARTICIPANTS: People aged 65 years or more referred for bilateral age-related cataract surgery during 2013-16, followed for maximum of 24 months after study entry or until six months after second eye surgery, whichever was shorter. MAIN OUTCOME MEASURES: Primary outcome: age- and sex-adjusted incidence of falls. SECONDARY OUTCOMES: visual acuity and refractive error. RESULTS: The mean age of the 409 included participants was 75.4 years (SD, 5.4 years); 220 were women (54%). Age- and sex-adjusted fall incidence prior to surgery was 1.17 (95% CI, 0.95-1.43) per year, 0.81 (95% CI, 0.63-1.04) per year after first eye surgery, and 0.41 (95% CI, 0.29-0.57) per year after second eye surgery. For the 118 participants who underwent second eye surgery and participated in all follow-up visits, age- and sex-adjusted incidence before (0.80 [95% CI, 0.55-1.15] falls per year) and after first eye surgery (0.81 [95% CI, 0.57-1.15] falls per year) was similar, but was lower after second eye surgery (0.32 [95% CI 0.21-0.50] falls per year). Mean habitual binocular visual acuity (logMAR) was 0.32 (SD, 0.21) before surgery, 0.15 (SD, 0.17) after first eye surgery, and 0.07 (SD, 0.15) after second eye surgery. CONCLUSIONS: First eye surgery substantially improves vision in older people with cataract, but second eye surgery is required to minimise fall incidence. Timely cataract surgery for both eyes not only optimises vision in older people with cataract, but also reduces their risk of injury from falls.

Risk factors for incident kidney disease in older adults: an Australian prospective population-based study.

BACKGROUND AND AIM: To determine risk factors for incident chronic kidney disease (CKD) in a large population-based cohort. METHODS: This prospective opt-in population-based cohort study is based on the 45 and Up Study, where New South Wales residents aged ≥45 years were randomly sampled from the Services Australia database and agreed to complete the 45 and Up Study baseline questionnaire and have their responses linked to their health data in routinely collected databases. The primary outcome was the development of incident CKD, defined as eGFR < 60 mL/min/1.73 m2 . CKD incidence was calculated using Poisson regression. Risk factors for incident CKD were assessed using Cox regression in multivariable models. RESULTS: In 39 574 participants who did not have CKD at enrolment, independent factors associated with developing CKD included: older age, regional residence (HR 1.38 (1.27-1.50) for outer regional vs major city), smoking (1.13 (1.00-1.27) for current smoker vs non-smoker), obesity (1.25 (1.16-1.35) for obese vs normal body mass index), diabetes mellitus (1.41 (1.33-1.50)), hypertension (1.53 (1.44-1.62)), coronary heart disease (1.13 (1.07-1.20)), depression/anxiety (1.16 (1.09-1.24)) and cancer (1.29 (1.20-1.39)). Migrants were less likely to develop CKD compared with people born in Australia (0.88 (0.83-0.94)). Gender, partner status and socioeconomic factors were not independently associated with developing CKD. CONCLUSIONS: This large population-based study found multiple modifiable and non-modifiable factors were independently associated with developing CKD. In the Australian setting, the risk of CKD was higher with regional residence. Differences according to socioeconomic status were predominantly explained by age, comorbidities and harmful health-related behaviours.

Incidence of early diaphragmatic dysfunction after lung transplantation: results of a prospective observational study.

BACKGROUND: Diaphragmatic dysfunction is common after cardiothoracic surgery, but few studies report its incidence and consequences after lung transplantation. We aimed to estimate the incidence of diaphragmatic dysfunction using ultrasound in lung transplant patients up to 3 months postoperatively and evaluated the impact on clinical outcomes. METHODS: This was a single-center prospective observational cohort study of 27 lung transplant recipients using diaphragmatic ultrasound preoperatively, at 1 day, 1 week, 1 month, and 3 months postoperatively. Diaphragmatic dysfunction was defined as excursion < 10 mm in men and < 9 mm in women during quiet breathing. Clinical outcomes measured included duration of mechanical ventilation, length of stay (LOS) in Intensive Care (ICU), and hospital LOS. RESULTS: Sixty-two percentage of recipients experienced new, postoperative diaphragmatic dysfunction, but the prevalence fell to 22% at 3 months. No differences in clinical outcomes were found between those with diaphragmatic dysfunction compared to those without. Patients who experienced diaphragmatic dysfunction at 1 day postoperatively were younger and had a lower BMI than those who did not. CONCLUSIONS: Diaphragmatic dysfunction is common after lung transplant, improves significantly within 3 months, and did not impact negatively on duration of mechanical ventilation, LOS in ICU or hospital, or discharge destination.

Prevalence, incidence and risk factors of diabetes in Australian adults aged ≥45 years: A cohort study using linked routinely-collected data.

AIMS: To use linked routinely-collected health data to estimate diabetes prevalence and incidence in an Australian cohort of adults aged ≥45 years, and examine risk factors associated with incident disease. RESEARCH DESIGN AND METHODS: The EXamining ouTcomEs in chroNic Disease in the 45 and Up Study (EXTEND45) Study is a linked data study that combines baseline questionnaire responses from the population-based 45 and Up Study (2006-2009, n = 267,153) with multiple routinely-collected health databases up to December 2014. Among participants with ≥1 linked result for any laboratory test, diabetes status was determined from multiple data sources according to standard biochemical criteria, use of glucose-lowering medication or self-report, and the prevalence and incidence rate calculated. Independent risk factors of incident diabetes were examined using multivariable Cox regression. RESULTS: Among 152,169 45 and Up Study participants with ≥1 linked laboratory result in the EXTEND45 database (mean age 63.0 years; 54.9% female), diabetes prevalence was 10.8% (95% confidence interval [CI] 10.6%-10.9%). Incident disease in those without diabetes at baseline (n = 135,810; mean age 62.5 years; 56.1% female) was 10.0 per 1,000 person-years (95% CI 9.8-10.2). In all age groups, diabetes incidence was lower in women compared to men, an association that persisted in the fully adjusted analyses. Other independent risk factors of diabetes were older age, being born outside of Australia (with the highest rate of 19.2 per 1,000 person-years observed in people born in South and Central Asia), lower education status, lower annual household income, residence in a major city, family history of diabetes, personal history of cardiovascular disease or hypertension, higher body mass index, smoking and long sleeping hours. CONCLUSIONS: Our study represents an efficient approach to assessing diabetes frequency and its risk factors in the community. The infrastructure provided by the EXTEND45 Study will be useful for diabetes surveillance and examining other important clinical and epidemiological questions.

Incidence and Associations of Chronic Kidney Disease in Community Participants With Diabetes: A 5-Year Prospective Analysis of the EXTEND45 Study.

OBJECTIVE: To determine the incidence of and factors associated with an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 in people with diabetes. RESEARCH DESIGN AND METHODS: We identified people with diabetes in the EXamining ouTcomEs in chroNic Disease in the 45 and Up Study (EXTEND45), a population-based cohort study (2006-2014) that linked the Sax Institute's 45 and Up Study cohort to community laboratory and administrative data in New South Wales, Australia. The study outcome was the first eGFR measurement <60 mL/min/1.73 m2 recorded during the follow-up period. Participants with eGFR < 60 mL/min/1.73 m2 at baseline were excluded. We used Poisson regression to estimate the incidence of eGFR <60 mL/min/1.73 m2 and multivariable Cox regression to examine factors associated with the study outcome. RESULTS: Of 9,313 participants with diabetes, 2,106 (22.6%) developed incident eGFR <60 mL/min/1.73 m2 over a median follow-up time of 5.7 years (interquartile range, 3.0-5.9 years). The eGFR <60 mL/min/1.73 m2 incidence rate per 100 person-years was 6.0 (95% CI 5.7-6.3) overall, 1.5 (1.3-1.9) in participants aged 45-54 years, 3.7 (3.4-4.0) for 55-64 year olds, 7.6 (7.1-8.1) for 65-74 year olds, 15.0 (13.0-16.0) for 75-84 year olds, and 26.0 (22.0-32.0) for those aged 85 years and over. In a fully adjusted multivariable model incidence was independently associated with age (hazard ratio 1.23 per 5-year increase; 95% CI 1.19-1.26), geography (outer regional and remote versus major city: 1.36; 1.17-1.58), obesity (obese class III versus normal: 1.44; 1.16-1.80), and the presence of hypertension (1.52; 1.33-1.73), coronary heart disease (1.13; 1.02-1.24), cancer (1.30; 1.14-1.50), and depression/anxiety (1.14; 1.01-1.27). CONCLUSIONS: In participants with diabetes, the incidence of an eGFR <60 mL/min/1.73 m2 was high. Older age, remoteness of residence, and the presence of various comorbid conditions were associated with higher incidence.

Dysphagia screening and risks of pneumonia and adverse outcomes after acute stroke: An international multicenter study.

BACKGROUND: Dysphagia is associated with aspiration pneumonia after stroke. Data are limited on the influences of dysphagia screen and assessment in clinical practice. AIMS: To determine associations between a "brief" screen and "detailed" assessment of dysphagia on clinical outcomes in acute stroke patients. METHODS: A prospective cohort study analyzed retrospectively using data from a multicenter, cluster cross-over, randomized controlled trial (Head Positioning in Acute Stroke Trial [HeadPoST]) from 114 hospitals in nine countries. HeadPoST included 11,093 acute stroke patients randomized to lying-flat or sitting-up head positioning. Herein, we report predefined secondary analyses of the association of dysphagia screening and assessment and clinical outcomes of pneumonia and death or disability (modified Rankin scale 3-6) at 90 days. RESULTS: Overall, 8784 (79.2%) and 3917 (35.3%) patients were screened and assessed for dysphagia, respectively, but the frequency and timing for each varied widely across regions. Neither use of a screen nor an assessment for dysphagia was associated with the outcomes, but their results were compared to "screen-pass" patients, those who failed had higher risks of pneumonia (adjusted odds ratio [aOR] = 3.00, 95% confidence interval [CI] = 2.18-4.10) and death or disability (aOR = 1.66, 95% CI = 1.41-1.95). Similar results were evidence for the results of an assessment for dysphagia. Subsequent feeding restrictions were related to higher risk of pneumonia in patients failed dysphagia screen or assessment (aOR = 4.06, 95% CI = 1.72-9.54). CONCLUSIONS: Failing a dysphagia screen is associated with increased risks of pneumonia and poor clinical outcome after acute stroke. Further studies concentrate on determining the effective subsequent feeding actions are needed to improve patient outcomes.

A Smartphone App to Assist Smoking Cessation Among Aboriginal Australians: Findings From a Pilot Randomized Controlled Trial.

BACKGROUND: Mobile health (mHealth) apps have the potential to increase smoking cessation, but little research has been conducted with Aboriginal communities in Australia. OBJECTIVE: We conducted a pilot study to assess the feasibility and acceptability and explore the effectiveness of a novel mHealth app to assist Aboriginal people to quit smoking. METHODS: A pilot randomized controlled trial (RCT) and process evaluation comprising usage analytics data and in-depth interviews was conducted. Current Aboriginal smokers (>16 years old), who were willing to make a quit attempt in the next month, were recruited from Aboriginal Community Controlled Health Services and a government telephone coaching service. The intervention was a multifaceted Android or iOS app comprising a personalized profile and quit plan, text and in-app motivational messages, and a challenge feature allowing users to compete with others. The comparator was usual cessation support services. Outcome data collection and analysis were conducted blinded to treatment allocation. The primary outcome was self-reported continuous smoking abstinence verified by carbon monoxide breath testing at 6 months. Secondary outcomes included point prevalence of abstinence and use of smoking cessation therapies and services. RESULTS: A total of 49 participants were recruited. Competing service delivery priorities, the lack of resources for research, and lack of support for randomization to a control group were the major recruitment barriers. At baseline, 23/49 (47%) of participants had tried to quit in recent weeks. At 6-month follow-up, only 1 participant (intervention arm) was abstinent. The process evaluation highlighted low to moderate app usage (3-10 new users per month and 4-8 returning users per month), an average of 2.9 sessions per user per month and 6.3 min per session. Key themes from interviews with intervention participants (n=15) included the following: (1) the powerful influence of prevailing social norms around acceptability of smoking; (2) high usage of mobile devices for phone, text, and social media but very low use of other smartphone apps; (3) the role of family and social group support in supporting quit attempts; and (4) low awareness and utilization of smoking cessation support services. Despite the broad acceptability of the app, participants also recommended technical improvements to improve functionality, greater customization of text messages, integration with existing social media platforms, and gamification features. CONCLUSIONS: Smoking cessation apps need to be integrated with commonly used functions of mobile phones and draw on social networks to support their use. Although they have the potential to increase utilization of cessation support services and treatments, more research is needed to identify optimal implementation models. Robust evaluation is critical to determine their impact; however, an RCT design may not be feasible in this setting.

Associations between clinical indicators of quality and aged-care residents' needs and consumer and staff satisfaction: the first Australian study.

Objectives To ascertain Australian multistate prevalence and incidence of five commonly collected clinical indicators of aged-care home quality and to measure associations between these clinical indicators and levels of care needs and consumer and staff satisfaction. Methods A retrospective analysis of national audit data collected from 426 facilities between 2015 and 2016 was performed. Regression models were used to examine associations between five clinical indicators (falls, pressure injury, physical restraint, unplanned weight loss and polypharmacy) and level of care needs measured by the Aged Care Funding Instrument (ACFI) and consumer and care staff survey responses. Results With the exception of polypharmacy, commonly collected negative clinical outcomes were rare events. Compared with care homes with <25% of residents having high-level care needs (high ACFI), homes with 25<75% high-ACFI residents had more occurrences of all negative clinical outcomes except pressure injury. Homes with ≥75% high-ACFI residents reported the highest rates of polypharmacy (odds ratio 1.48, 95% confidence interval 1.39 - 1.57). Falls, unplanned weight loss and pressure injury were inversely associated with satisfaction scores adjusted for residents' level of care needs. Conclusions This first Australian study of multistate clinical indicator data suggests interpretation of clinical indicators of aged-care home quality requires consideration of the level of residents' care needs. What is known about the topic? Many Australian aged-care providers use quality indicators (QI) through benchmarking companies or in-house programs. The five most widely used aged-care clinical QIs in Australia are falls, pressure injury, physical restraint, unplanned weight loss and polypharmacy. Prevalence and incidence of these QIs are highly variable among Australian studies. A consistent message in the international literature is that residents' clinical characteristics influence QI outcomes at baseline and may continue to influence outcomes over time. Study of associations between Australian aged-care home characteristics and QI outcomes has been limited. What does this paper add? This is the first Australian study of multistate clinical QI data. It is also the first to consider the level of resident care needs in the interpretation of clinical QI outcomes and exploration of the association between level of consumer and staff satisfaction and QI outcomes. What are the implications for practitioners? Understanding the connections between aged-care home characteristics, consumer and staff perceptions and clinical QIs is crucial in the meaningful interpretation of QI outcomes in context. With the recent introduction of the National Aged Care Quality Indicator Program, it is timely to review national policy, to gauge current quality of care and the measure of care quality in the sector, and to develop directions for possible research to inform and resolve debates regarding the potential influence and unplanned effects that such a program may have.

Risk factors for falls among older Aboriginal and Torres Strait Islander people in urban and regional communities.

OBJECTIVE: To examine associations between fall risk factors identified previously in other populations and falls among Aboriginal people aged 60 years and older, living in New South Wales, Australia. METHODS: Interviews were conducted with older Aboriginal people in five urban and regional communities. Associations between past falls and 22 fall predictor variables were examined using linear and multiple regression analyses. RESULTS: Of the 336 participants, 80 people (24%) reported at least one fall in the past year, and 34 (10%) reported two or more falls. Participants had an increased fall risk if they were female; used three or more medications; had arthritis, macular degeneration, depression, history of stroke; were unable to do their own housework; or were unable to do their own shopping. CONCLUSION: Falls were experienced by one-quarter of study participants. Fall risk factors identified for older Aboriginal people appear to be similar to those identified in the general population. Understanding of fall risk factors may assist with the development of appropriate and effective community-led fall prevention programs.

Visual and refractive associations with falls after first-eye cataract surgery.

PURPOSE: To clarify the effect of first-eye cataract surgery on the incidence of falls and identify components of visual function associated with fall risk. SETTING: Eight public hospital eye clinics in Sydney, Melbourne, and Perth, Australia. DESIGN: Prospective cohort study. METHODS: The study recruited patients who had bilateral cataract, were aged 65 years or older, and were on public hospital cataract surgery waiting lists. Comprehensive assessments of vision, physical function, and exercise activity were performed before and after first-eye cataract surgery. Falls were reported prospectively for up to 2 years and associations with falls were assessed using generalized linear mixed models. RESULTS: Of the 329 patients recruited, 196 (66.6%) completed first-eye surgery within the study period. First-eye cataract surgery reduced incident falls by 33% (adjusted incidence rate ratio 0.67; 95% confidence interval [CI], 0.49-0.92; P = .01). Poorer dominant-eye visual acuity was associated with falls during the study timeline (incidence rate ratio, 2.20; 95% CI, 1.02-4.74; P = .04). Patients with larger than a spherical equivalent of ±0.75 diopter change in the spectacle lens (operated eye) had a 2-fold greater incidence of falls in the period after first-eye cataract surgery than those with less or no change in lens power (incidence rate ratio, 2.17; 95% CI, 1.23-3.85; P = .008). CONCLUSIONS: First-eye cataract surgery significantly reduced incident falls. Major changes in the dioptric power of spectacle correction of the operated eye after surgery increased the fall risk. Cautious postoperative refractive management is important to maximize the benefit of cataract surgery as a fall-prevention measure.

Fear of falling and physical function in older adults with cataract: Exploring the role of vision as a moderator.

AIM: To examine fear of falling and associated factors in a cohort of older adults with cataract, and investigate the interplay of vision and physical function with respect to fear of falling. METHODS: We analyzed baseline data from a longitudinal study of adults aged ≥65 years referred for cataract surgery. Fear of falling was assessed by the Short Falls Efficacy Scale-International. Physical function was determined by the Short Physical Performance Battery. Participants underwent assessment of visual acuity, contrast sensitivity, visual disability, quality of life, depressive symptoms, exercise frequency, comorbidity and falls history. Factors associated with fear of falling were assessed using linear regression. Planned stepwise regression investigated vision as a potential moderator of the relationship between physical function and fear of falling. RESULTS: Among 322 participants, 32.9 % (n = 106) showed high fear of falling. Poorer physical function, more comorbidities and greater visual disability were independently associated with a higher fear of falling (all P < 0.001). Visual disability moderated the relationship between physical function and fear of falling (ß = -0.10, P = 0.04). The impact of physical function on fear of falling was strongest in participants with higher (+1 standard deviation above the mean) visual disability (b = -0.21, P < 0.001). CONCLUSIONS: Fear of falling in older adults with cataract is greatest in those with poorer physical function and higher levels of visual disability. Perceived visual ability has a moderating role in the relationship between physical function and fear of falling; physical function alone might not adequately predict falls concern.

While We Waited: Incidence and Predictors of Falls in Older Adults With Cataract.

PURPOSE: Strong evidence indicates an increased fall risk associated with cataract. Although cataract surgery can restore sight, lengthy wait times are common for public patients in many high-income countries. This study reports incidence and predictors of falls in older people with cataract during their surgical wait. METHODS: Data from a prospective study of falls in adults aged ≥65 years who were awaiting cataract surgery in public hospitals in Australia were analyzed. Participants underwent assessment of vision, health status, and physical function, and recalled falls in the previous 12 months. Falls were self-reported prospectively during the surgical wait. RESULTS: Of 329 participants, mean age was 75.7 years; 55.2% were female. A total of 267 falls were reported by 101 (30.7%) participants during the surgical wait (median observation time, 176 days): an incidence of 1.2 falls per person-year (95% confidence interval [CI] 1.0-1.3). Greater walking activity (incidence rate ratio [IRR] 1.06, 95% CI 1.01-1.10; P = 0.02, per additional hour/week), poorer health-related quality of life (IRR 1.12, 95% CI 1.05-1.20; P < 0.001, per 5-unit decrease), and a fall in the prior 12 months (IRR 2.48, 95% CI 1.57-3.93; P < 0.001) were associated with incident falls. No visual measure independently predicted fall risk. More than one-half (51.7%) of falls were injurious. CONCLUSIONS: We found a substantial rate of falls and fall injury in older adults with cataract who were awaiting surgery. Within this relatively homogenous cohort, measures of visual function alone inadequately predicted fall risk. Assessment of exposure to falls through physical activity frequency may prove valuable in identifying those more likely to fall during the surgical wait.

Effects of ischaemic conditioning on major clinical outcomes in people undergoing invasive procedures: systematic review and meta-analysis.

OBJECTIVE:  To summarise the benefits and harms of ischaemic conditioning on major clinical outcomes in various settings. DESIGN:  Systematic review and meta-analysis. DATA SOURCES:  Medline, Embase, Cochrane databases, and International Clinical Trials Registry platform from inception through October 2015. STUDY SELECTION:  All randomised controlled comparisons of the effect of ischaemic conditioning on clinical outcomes were included. DATA EXTRACTION:  Two authors independently extracted data from individual reports. Reports of multiple intervention arms were treated as separate trials. Random effects models were used to calculate summary estimates for all cause mortality and other pre-specified clinical outcomes. All cause mortality and secondary outcomes with P<0.1 were examined for study quality by using the GRADE assessment tool, the effect of pre-specified characteristics by using meta-regression and Cochran C test, and trial sequential analysis by using the Copenhagen Trial Unit method. RESULTS:  85 reports of 89 randomised comparisons were identified, with a median 80 (interquartile range 60-149) participants and median 1 (range 1 day-72 months) month intended duration. Ischaemic conditioning had no effect on all cause mortality (68 comparisons; 424 events; 11 619 participants; risk ratio 0.96, 95% confidence interval 0.80 to 1.16; P=0.68; moderate quality evidence) regardless of the clinical setting in which it was used or the particular intervention related characteristics. Ischaemic conditioning may reduce the rates of some secondary outcomes including stroke (18 trials; 5995 participants; 149 events; risk ratio 0.72, 0.52 to 1.00; P=0.048; very low quality evidence) and acute kidney injury (36 trials; 8493 participants; 1443 events; risk ratio 0.83, 0.71 to 0.97; P=0.02; low quality evidence), although the benefits seem to be confined to non-surgical settings and to mild episodes of acute kidney injury only. CONCLUSIONS:  Ischaemic conditioning has no overall effect on the risk of death. Possible effects on stroke and acute kidney injury are uncertain given methodological concerns and low event rates. Adoption of ischaemic conditioning cannot be recommended for routine use unless further high quality and well powered evidence shows benefit.

Depressive symptoms in older adults awaiting cataract surgery.

BACKGROUND: To assess the prevalence and predictors of depressive symptoms in a cohort of older adults awaiting cataract surgery and establish threshold vision at which depressive symptoms may emerge. DESIGN: Analysis of cross-sectional baseline data from a longitudinal cohort study of patients aged ≥65 years on Australian public hospital cataract surgery waiting lists. PARTICIPANTS: We included 329 participants enrolled October 2013-August 2015. METHODS: Participants completed assessment of depressive symptoms, visual disability, quality of life, social participation and exercise frequency at least one month prior to cataract surgery. High and low contrast habitual vision was examined and systemic comorbidities noted. MAIN OUTCOME MEASURE: Depressive symptoms prior to first eye cataract surgery. RESULTS: The prevalence of depressive symptoms was 28.6% (94/329). Univariate analysis identified that participants with poorer high contrast vision, reduced quality of life, greater patient-reported visual disability, higher comorbidity score and who were taking more medications were more likely to exhibit signs of depression. Greater patient-reported visual disability (P = 0.02), reduced quality of life (P = 0.003) and a higher comorbidity score (P = 0.02) remained significantly associated with depressive symptoms in the multivariable model. Depressive symptoms emerged at a visual acuity of 6/12. CONCLUSIONS: These findings demonstrate a high prevalence of depressive symptoms in older persons with cataract, emerging at modest levels of vision loss. Efficient referral processes, timely surgical management, and improved screening and coordinated treatment of depressive symptoms during the surgical wait may minimize the negative psychological effects of cataract in this already vulnerable population.

Trends in incidence and survival for anal cancer in New South Wales, Australia, 1972-2009.

INTRODUCTION: Little is known about the incidence and survival of anal cancer in New South Wales (NSW), Australia, as anal cancer cases are often grouped together with other colorectal cancers in descriptive epidemiological analyses. METHODS: We studied patterns and trends in the incidence and survival of people diagnosed with anal cancer in NSW, Australia, 1972-2009 (n=2724). We also predicted anal cancer incidence in NSW during 2010-2032. Given the human papilloma virus-associated aetiology for most anal cancers, we quantified these changes over time in incidence and survival by histological subtype: anal squamous cell carcinoma (ASCC); and anal adenocarcinoma (AAC). RESULTS: There was a linear increase in incident anal cancer cases in NSW with an average annual percentage change (AAPC) of 1.6 (95% CI 1.1-2.0) such that, in combination with age-period-cohort modelling, we predict there will be 198 cases of anal cancer in the 2032 calendar year (95% CI 169-236). Almost all of these anal cancer cases are projected to be ASCC (94%). Survival improved over time regardless of histological subtype. However, five-year relative survival was substantially higher for people with ASCC (70% (95% CI 66-74%)) compared to AAC (51% (95% CI 43-59%)), a 37% difference. Survival was also greater for women (69% (95% CI 64-73%)) with ASCC compared to men (55% (95% CI 50-60%)). It was not possible to estimate survival by stage at diagnosis particularly given that 8% of all cases were recorded as having distant stage and 22% had missing stage data. INTERPRETATION: Aetiological explanations, namely exposure to oncogenic types of human papillomavirus, along with demographic changes most likely explain the actual and projected increase in ASCC case numbers. Survival differences by gender and histological subtype point to areas where further research is warranted to improve treatment and outcomes for all anal cancer patients.

Traditional and Emerging Lifestyle Risk Behaviors and All-Cause Mortality in Middle-Aged and Older Adults: Evidence from a Large Population-Based Australian Cohort.

BACKGROUND: Lifestyle risk behaviors are responsible for a large proportion of disease burden worldwide. Behavioral risk factors, such as smoking, poor diet, and physical inactivity, tend to cluster within populations and may have synergistic effects on health. As evidence continues to accumulate on emerging lifestyle risk factors, such as prolonged sitting and unhealthy sleep patterns, incorporating these new risk factors will provide clinically relevant information on combinations of lifestyle risk factors. METHODS AND FINDINGS: Using data from a large Australian cohort of middle-aged and older adults, this is the first study to our knowledge to examine a lifestyle risk index incorporating sedentary behavior and sleep in relation to all-cause mortality. Baseline data (February 2006- April 2009) were linked to mortality registration data until June 15, 2014. Smoking, high alcohol intake, poor diet, physical inactivity, prolonged sitting, and unhealthy (short/long) sleep duration were measured by questionnaires and summed into an index score. Cox proportional hazards analysis was used with the index score and each unique risk combination as exposure variables, adjusted for socio-demographic characteristics. During 6 y of follow-up of 231,048 participants for 1,409,591 person-years, 15,635 deaths were registered. Of all participants, 31.2%, 36.9%, 21.4%, and 10.6% reported 0, 1, 2, and 3+ risk factors, respectively. There was a strong relationship between the lifestyle risk index score and all-cause mortality. The index score had good predictive validity (c index = 0.763), and the partial population attributable risk was 31.3%. Out of all 96 possible risk combinations, the 30 most commonly occurring combinations accounted for more than 90% of the participants. Among those, combinations involving physical inactivity, prolonged sitting, and/or long sleep duration and combinations involving smoking and high alcohol intake had the strongest associations with all-cause mortality. Limitations of the study include self-reported and under-specified measures, dichotomized risk scores, lack of long-term patterns of lifestyle behaviors, and lack of cause-specific mortality data. CONCLUSIONS: Adherence to healthy lifestyle behaviors could reduce the risk for death from all causes. Specific combinations of lifestyle risk behaviors may be more harmful than others, suggesting synergistic relationships among risk factors.

All-cause mortality effects of replacing sedentary time with physical activity and sleeping using an isotemporal substitution model: a prospective study of 201,129 mid-aged and older adults.

BACKGROUND: Sedentary behaviour, sleeping, and physical activity are thought to be independently associated with health outcomes but it is unclear whether these associations are due to the direct physiological effects of each behaviour or because, across a finite 24-hour day, engagement in one behavior requires displacement of another. The aim of this study was to examine the replacement effects of sedentary behaviour (total sitting, television/computer screen time combined), sleeping, standing, walking, and moderate-to-vigorous physical activity on all-cause mortality using isotemporal substitution modelling. METHODS: Longitudinal analysis (4.22 ± 0.9 years follow-up/849,369 person-years) of 201,129 participants of the 45 and Up study aged ≥45 years from New South Wales, Australia. RESULTS: Seven thousand four hundred and sixty deaths occurred over follow-up. There were beneficial associations for replacing total sitting time with standing (per-hour HR: 95 % CI: 0.95, 0.94-0.96), walking (0.86, 0.81-0.90), moderate-to-vigorous physical activity (0.88, 0.85-0.90), and sleeping in those sleeping ≤ 7 h/day (0.94, 0.90-0.98). Similar associations were noted for replacing screen time. Replacing one hour of walking or moderate-to-vigorous physical activity with any other activity class was associated with an increased mortality risk by 7-18%. Excluding deaths in the first 24 months of the follow up and restricting analyses to those who were healthy at baseline did not materially change the above observations. CONCLUSION: Although replacing sedentary behaviour with walking and moderate-to-vigorous physical activity are associated with the lowest mortality risk, replacements with equal amounts of standing and sleeping (in low sleepers only) are also linked to substantial mortality risk reductions.

Revisiting lifestyle risk index assessment in a large Australian sample: should sedentary behavior and sleep be included as additional risk factors?

OBJECTIVE: Most studies on multiple health behaviors include physical inactivity, alcohol, diet, and smoking (PADS), with few including emerging lifestyle risks such as sleep or sitting. We examined whether adding sitting and sleep to a conventional lifestyle risk index improves the prediction of cross-sectional health outcomes (self-rated health, quality of life, psychological distress, and physical function). We also explored the demographic characteristics of adults with these multiple risk behaviors. METHODS: We used baseline data of an Australian cohort study (n=191,853) conducted in 2006-2008 in New South Wales. Lifestyle risk index was operationalized as 1) PADS, 2) PADS+sitting, 3) PADS+sleep, and 4) PADS+sitting+sleep. We estimated receiver operating characteristic curve for self-reported binary health outcomes and calculated the area under the curve to illustrate how well each index classified the outcome. We used multiple logistic regression to determine the demographic characteristics of adults with multiple lifestyle risks. RESULTS: Adding sleep duration but not sitting time to the PADS index significantly improved the classification of all health outcomes. Men, those aged 45-54years, those with 10 years of education or less, and those living in regional/remote areas had higher odds of multiple risk behaviors. CONCLUSIONS: Future research on multiple health behaviors might benefit from including sleep as an additional behavior. In Australia, unhealthy lifestyles tend to cluster in adults with certain demographic characteristics.
