The role of complementary medicine health literacy in health communication and decision-making

Background

Globally, complementary medicine (CM) product use is high-including vitamins, minerals and herbal medicines. The overuse of CM raises concerns about medicine sustainability that are critical considerations for human and planetary health. Poor CM health literacy may lead to the unnecessary use of CM. This is the first study to explore associations between CM use, CM health literacy, and concurrent use of CM with conventional health care in an Australian population with a view to identifying priority areas for intervention.

Methods

Cross-sectional online study of Australian adults (N = 2019). A 50-item survey measured demographic and health characteristics, health care and treatment use, medicine use disclosure to health care providers, and CM health literacy. Descriptive statistics, Spearman's correlations and Chi-square analysis were used to analyse preliminary findings.

Results

In the previous year 49.1% of participants used a CM product. A greater proportion of those who used CM products (88.7%, <0.001), compared to those who did not, used a prescription or over-the-counter pharmaceutical. Lower levels of CM health literacy were associated with herbal supplement use (not vitamin/mineral supplement use) and with disclosing CM use to a medical doctor or pharmacist (p < 0.01). Those who consulted with a GP, specialist or pharmacist, who self-prescribed CM, or used both CM and pharmaceutical medicines had better CM health literacy (p < 0.001) than those who did not. Conversely, those who consulted a CM practitioner had lower CM health literacy than those who did not (p < 0.001).

Conclusions

The findings suggest that people with lower CM health literacy may be unsure about using CM products, while those with better CM health literacy may have more self-efficacy for making treatment decisions. Interventions are needed to improve public CM health literacy and encourage shared decision-making to ensure safe, effective and sustainable treatment decisions.

Key messages

People with higher levels of CM health literacy appear to have greater self-efficacy for making treatment decisions, while those with lower CM health literacy are more likely to seek treatment advice. Interventions are needed to ensure people using CM products are communicating with health practitioners about their treatment choices to facilitate safe, effective and sustainable treatment decisions.

The value of non-invasive computed tomography coronary angiography in imaging patients with coronary artery bypass grafts

INTRODUCTION

Invasive coronary angiography (ICA) is associated with higher complication rates in patients following coronary artery bypass surgery (CABG). CT coronary angiography (CTCA) has emerged as an attractive alternative. We assessed the impact of CTCA on subsequent ICA.

METHODS

We identified 213 CABG patients undergoing CTCA between 2015 and 2018. In 151 the indication was suspected recurrence of angina. We then identified patients undergoing ICA within 1 year of CTCA.

RESULTS

CTCA obviated the need for ICA in 115 cases (76%). CTCA was better at identifying targets for percutaneous coronary intervention (PCI) to saphenous vein grafts (SVG's) than to native vessels (89% vs 47%). 7 out of 10 lesions of "probable" significance by CTCA proved flow-limiting, and 4 out of 13 "indeterminate" lesions. CTCA concordance was 97% for left internal mammary (LIMA) grafts.

CONCLUSION

CTCA directed management in a majority of patients without ICA. It identified a cohort of patients likely to be candidates for SVG PCI, but was less effective in identifying PCI targets in the native vessels. CTCA renders invasive LIMA cannulation redundant unless a target lesion is suspected.

1098 Altered Actigraphic Behavioral Activity Rhythm In Depression

Introduction

Disturbances in sleep and behavioral activity rhythms (BAR) are frequently observed in individuals with depression. However, it remains unclear how activity variability across the 24-hour period is specifically associated with this disorder. The present study aimed to examine actigraphy-measured sleep and BAR in depression.

Methods

As part of a larger study, fourteen patients with DSM-5 major depressive episode (27.8±7.7 years, 69.2% female) and 13 healthy controls (21.8±1.2 years, 76.5% female) were evaluated with 7-14 days of wrist-actigraphy. Actigraphy-derived sleep parameters included total sleep time (TST), sleep onset latency (SOL), wake after sleep onset (WASO), and sleep efficiency (SE). Minute-by-minute activity counts were aggregated into hour-by-hour bins; hourly mean activity levels were then generated to depict 24-hour activity patterns (i.e., BAR). Factorial (GroupxTime) mixed models were conducted to examine whether BAR differed between patients with MDD and controls. Generalized Additive Models (GAM), by fitting smoothed nonlinear curves to log-transformed aggregated activity, were performed as exploratory analyses to characterize onset (UP slope) and offset (DOWN slope) of BAR.

Results

Compared to healthy controls, patients with MDD exhibited greater actigraphic TST (p=.026); no other between-group differences were detected for the remaining sleep parameters. Significant between-group differences were observed for mean activity during wakefulness (p<.001). Mixed models assessing hour-by-hour daily activity revealed a significant GroupxTime interaction (p=.001) with significant main effects of group (p=.017) and time (p<.001); patients with MDD had lower activity from 6 to 9 pm (ps<.005). Exploratory GAMs results showed an attenuated DOWN slope in patients with MDD (p=.014), indicating a slower decrease in activity during the evening.

Conclusion

Altered BAR, characterized by an overall dampened activity pattern that was most prominent during the evening, was associated with depression. Furthermore, patients with MDD took longer to wind down in the evening. Future studies are needed to explore the potential benefits of adjunctive interventions addressing both BAR along with sleep in mitigating symptoms of depression.

Exploring talk about sexuality and living gay social lives among Chinese and South Asian gay and bisexual men in Auckland, New Zealand

Objective: To identify ways Chinese and South Asian gay and bisexual men living in Auckland talk about issues related to sexuality and experiences of living 'gay social lives.' Results will be available to inform health policy and practice.Design: A qualitative design with individual interviews and thematic analysis was used. Semi-structured digitally recorded interviews were undertaken with 27 Chinese and 17 South Asian gay and bisexual men living in Auckland.Results: Four themes in the data related to talk about sexuality and living gay social lives are reported: (a) 'Happy in my skin': Being gay is Ok! (b) 'To come out or not': Managing sexual identity, (c) 'Places to go, people to see': Connecting with others, and (d) 'What's wrong with being Asian': Tolerating discrimination.Conclusion: There are many similarities in the ways these men talked about their identity and sexuality that can be usefully considered by health policy makers and service planners. The concept of gay (and bisexual) sexuality had some salience for the men interviewed, despite the adoption and acknowledgement of same-sex identity being a relatively new phenomenon in some Asian countries. This supports the use of these terms in local health interventions. However, as these men closely managed their gay identity and typically had not disclosed their sexuality to others, including healthcare professionals, interventions to address the skills and comfort of healthcare providers in addressing sexuality in clinical settings appear warranted to facilitate optimal healthcare. These men are not well connected with others and this has implications for HIV health promotion that is based on creating cultural norms among networks to encourage safe sex. Discrimination results in many Chinese and South Asian gay and bisexual men disengaging from connecting with others and should be addressed.

Viscous placebo and carbohydrate breakfasts similarly decrease appetite and increase resistance exercise performance compared with a control breakfast in trained males

Given the common view that pre-exercise nutrition/breakfast is important for performance, the present study investigated whether breakfast influences resistance exercise performance via a physiological or psychological effect. Twenty-two resistance-trained, breakfast-consuming men completed three experimental trials, consuming water-only (WAT), or semi-solid breakfasts containing 0 g/kg (PLA) or 1·5 g/kg (CHO) maltodextrin. PLA and CHO meals contained xanthan gum and low-energy flavouring (approximately 122 kJ), and subjects were told both 'contained energy'. At 2 h post-meal, subjects completed four sets of back squat and bench press to failure at 90 % ten repetition maximum. Blood samples were taken pre-meal, 45 min and 105 min post-meal to measure serum/plasma glucose, insulin, ghrelin, glucagon-like peptide-1 and peptide tyrosine-tyrosine concentrations. Subjective hunger/fullness was also measured. Total back squat repetitions were greater in CHO (44 (sd 10) repetitions) and PLA (43 (sd 10) repetitions) than WAT (38 (sd 10) repetitions; P < 0·001). Total bench press repetitions were similar between trials (WAT 37 (sd 7) repetitions; CHO 39 (sd 7) repetitions; PLA 38 (sd 7) repetitions; P = 0·130). Performance was similar between CHO and PLA trials. Hunger was suppressed and fullness increased similarly in PLA and CHO, relative to WAT (P < 0·001). During CHO, plasma glucose was elevated at 45 min (P < 0·05), whilst serum insulin was elevated (P < 0·05) and plasma ghrelin suppressed at 45 and 105 min (P < 0·05). These results suggest that breakfast/pre-exercise nutrition enhances resistance exercise performance via a psychological effect, although a potential mediating role of hunger cannot be discounted.

Time-Integrated Neutrino Source Searches with 10 Years of IceCube Data

This Letter presents the results from pointlike neutrino source searches using ten years of IceCube data collected between April 6, 2008 and July 10, 2018. We evaluate the significance of an astrophysical signal from a pointlike source looking for an excess of clustered neutrino events with energies typically above ∼1  TeV among the background of atmospheric muons and neutrinos. We perform a full-sky scan, a search within a selected source catalog, a catalog population study, and three stacked Galactic catalog searches. The most significant point in the northern hemisphere from scanning the sky is coincident with the Seyfert II galaxy NGC 1068, which was included in the source catalog search. The excess at the coordinates of NGC 1068 is inconsistent with background expectations at the level of 2.9σ after accounting for statistical trials from the entire catalog. The combination of this result along with excesses observed at the coordinates of three other sources, including TXS 0506+056, suggests that, collectively, correlations with sources in the northern catalog are inconsistent with background at 3.3σ significance. The southern catalog is consistent with background. These results, all based on searches for a cumulative neutrino signal integrated over the 10 years of available data, motivate further study of these and similar sources, including time-dependent analyses, multimessenger correlations, and the possibility of stronger evidence with coming upgrades to the detector.

What arguments and from whom are most influential in shaping public health policy: thematic content analysis of responses to a public consultation on the regulation of television food advertising to children in the UK

OBJECTIVES

We explore one aspect of the decision making process-public consultation on policy proposals by a national regulatory body-aiming to understand how public health policy development is influenced by different stakeholders.

DESIGN

We used thematic content analysis to explore responses to a national consultation on the regulation of television advertising of foods high in fat, salt and sugar aimed at children.

SETTING

UK.

RESULTS

139 responses from key stakeholder groups were analysed to determine how they influenced the regulator's initial proposals for advertising restrictions. The regulator's priorities were questioned throughout the consultation process by public health stakeholders. The eventual restrictions implemented were less strict in many ways than those originally proposed. These changes appeared to be influenced most by commercial, rather than public health, stakeholders.

CONCLUSIONS

Public health policy making appears to be considered as a balance between commercial and public health interests. Tactics such as the questioning and reframing of scientific evidence may be used. In this example, exploring the development of policy regulating television food advertising to children, commercial considerations appear to have led to a watering down of initial regulatory proposals, with proposed packages not including the measures public health advocates considered to be the most effective. This seems likely to have compromised the ultimate public health effectiveness of the regulations eventually implemented.

An exploration of healthcare providers' experiences and perspectives of Traditional and complementary medicine usage and disclosure by Indigenous cancer patients

Background

Traditional and complementary medicines (T&CM) are any form of medicine, practice, treatment, product, technology, knowledge system or ceremony outside of conventional medical practice that aims to prevent and/or treat illness and/or promote well-being. Alongside conventional cancer treatments, T&CM usage is increasing; with 19% of indigenous Australians with cancer reporting using T&CM. There is limited evidence surrounding T&CM use and disclosure by indigenous patients. Our aim was to explore healthcare providers’ views about usage, disclosure/non-disclosure of T&CM by Indigenous cancer patients.

Methods

Semi-structured, in-depth interviews with 18 healthcare providers, including three indigenous providers, at a large urban hospital providing care to Indigenous cancer patients were conducted to explore providers’ experiences and attitudes towards T&CM use by Indigenous cancer patients. An interpretive phenomenological approach was used to thematically analyse the data.

Results

Analysis revealed six themes: concern about risk; no ‘real’ benefits; perception of T&CM and conventional medicine as antithetical; barriers to disclosure; ‘patients’ choice’ a double-edged sword; and providers’ lack of knowledge about T&CM. Healthcare providers perceived discord between T&CM and conventional medicine. Most lacked knowledge of T&CM, and had concerns around negative-interactions with conventional treatments. They considered T&CM outside their role, citing this as reasoning for their lack of knowledge. Indigenous healthcare providers had greater understanding and openness towards T&CM.

Conclusions

Given the potential usage of T&CM by Indigenous cancer patients, providers need a more comprehensive understanding of T&CM in order to inform discussion and facilitate effective disclosure on this topic. If indigenous Australians with cancer feel that cancer care providers are unreceptive to discussing T&CM, patient care risks being compromised; particularly given the potential for negative interactions between T&CM and conventional cancer treatments. Fostering health care interactions where indigenous patients feel comfortable to discuss T&CM usage should be a priority for all cancer care services.

Exploring traditional and complementary medicine use by Indigenous Australian women undergoing gynaecological cancer investigations

BACKGROUND

Indigenous Australian women experience worse gynaecological cancer outcomes than non-Indigenous women. While traditional and complementary medicine (T&CM) is increasingly used by cancer patients alongside conventional treatments, little is known about T&CM use by Indigenous women. This study aimed to explore the beliefs, attitudes and experiences related to T&CM use and disclosure among Indigenous women undergoing gynaecological cancer investigations.

METHODS

A mixed-methods design explored T&CM use among Indigenous women who presented for gynaecological cancer investigation at an urban Queensland hospital (September 2016 and January 2018).

RESULTS

Fourteen women participated. The reported use (86%) and perceived value of T&CM was high among the participants, however, women reported major challenges in communicating with healthcare providers about T&CM, commonly associated with trust and rapport.

CONCLUSIONS

These findings highlight the need for strategies to facilitate culturally-appropriate doctor-patient communication around T&CM to foster trust and transparency in gynaecological cancer care for Indigenous women.

Older Filipino immigrants' reconfiguration of traditional filial expectations: a focus ethnographic study

BACKGROUND

One of the many socio-cultural issues impacting older immigrants in host countries is the cultural expectations of filial piety from their adult children.

OBJECTIVE

To understand older Filipino immigrants' beliefs and values towards filial expectations.

DESIGN

Focused ethnography.

RESULTS

Two major themes were identified. The first theme 'moving away from filial expectations' drew out older Filipino's changing views of cultural expectations from their adult children. The second theme 'maintaining cultural values through good family relationships' highlighted the importance of acknowledging the cultural values considered to be most important by older Filipinos, which was having harmonious relationships and avoiding family conflict.

CONCLUSION

The reconfigured expectation was salient with participants' who identified 'not being a burden' to their adult children and the ardent desire to maintain positive family relationships. Impact Statement: Nurses need to be aware of changes to our current understanding of filial piety when providing care to older Filipinos.

Accessing rural health services: Results from a qualitative narrative gerontological study

Objective

Explore how older adults’ talk about accessing rural community health services.

Methods

A qualitative narrative gerontological approach explored issues related to accessing health services in their community. Semi‐structured digitally recorded individual interviews were undertaken with 32 community‐dwelling older people aged between 75 and 93 years. A narrative data analytic process was undertaken. The COnsolidated criteria for REporting Qualitative research guidelines were followed to ensure rigour in this study.

Results

Three collective narratives resulted from the data analytic process: (a) “accessing local health services”; (b) “accessing specialist services”; and (c) “accessing emergency services.”

Conclusions

Narrators identified a number of issues related to accessing rural health services. These included long waiting times, lack of continuity in care provision by doctors and difficulties accessing specialist and emergency services. Nurses were frequently cited as a reliable point of contact for these older people. Expansion of nursing roles would enhance the provision of rural health‐care services.

Post-Ebola psychosocial experiences and coping mechanisms among Ebola survivors: a systematic review

OBJECTIVE

A myriad of physical and psychosocial sequelae have been reported among Ebola survivors from previous Ebola virus disease (EVD) outbreaks, including the most recent in West Africa. This review examines the various forms of psychological distress experienced by EVD survivors, family and community reactions to EVD survivors and EVD survivors' coping mechanisms.

METHODS

We conducted a literature search of original articles employing Medline (Ovid), PubMed, Web of Science, Scopus, CINAHL, EBSCO host academic search complete, PsycINFO (EBSCO) and Embase databases.

RESULTS

Our search identified 1890 articles of which 24 met our inclusion criteria. Various forms of psychological distress were prevalent among EVD survivors including depression, anxiety, anger, grief, guilt, flashbacks, sadness, worthlessness, substance addiction, suicidal tendencies and self-stigmatisation. Family and community responses to EVD survivors ranged from acceptance to rejection, isolation, stigmatisation and discrimination. EVD survivors' coping strategies included engagement with religious faith, EVD survivors associations and involvement in EVD prevention and control interventions.

CONCLUSION

Psychological distress, including that resulting from family and community stigma and discrimination, appears common among EVD survivors. Community-based mental health and psychosocial interventions integrated within a broader package of care for EVD survivors that also recognises the physical health challenges are required. Well-designed longitudinal studies can provide clear insights on the nature and trajectory of the psychosocial issues currently experienced by EVD survivors.

Constraints on Minute-Scale Transient Astrophysical Neutrino Sources

High-energy neutrino emission has been predicted for several short-lived astrophysical transients including gamma-ray bursts (GRBs), core-collapse supernovae with choked jets, and neutron star mergers. IceCube's optical and x-ray follow-up program searches for such transient sources by looking for two or more muon neutrino candidates in directional coincidence and arriving within 100 s. The measured rate of neutrino alerts is consistent with the expected rate of chance coincidences of atmospheric background events and no likely electromagnetic counterparts have been identified in Swift follow-up observations. Here, we calculate generic bounds on the neutrino flux of short-lived transient sources. Assuming an E^{-2.5} neutrino spectrum, we find that the neutrino flux of rare sources, like long gamma-ray bursts, is constrained to <5% of the detected astrophysical flux and the energy released in neutrinos (100 GeV to 10 PeV) by a median bright GRB-like source is <10^{52.5}  erg. For a harder E^{-2.13} neutrino spectrum up to 30% of the flux could be produced by GRBs and the allowed median source energy is <10^{52}  erg. A hypothetical population of transient sources has to be more common than 10^{-5}  Mpc^{-3}  yr^{-1} (5×10^{-8}  Mpc^{-3}  yr^{-1} for the E^{-2.13} spectrum) to account for the complete astrophysical neutrino flux.

Disclosure of complementary medicine use to medical providers: a systematic review and meta-analysis

Concomitant complementary medicine (CM) and conventional medicine use is frequent and carries potential risks. Yet, CM users frequently neglect to disclose CM use to medical providers. Our systematic review examines rates of and reasons for CM use disclosure to medical providers. Observational studies published 2003-2016 were searched (AMED, CINAHL, MEDLINE, PsycINFO). Eighty-six papers reporting disclosure rates and/or reasons for disclosure/non-disclosure of CM use to medical providers were reviewed. Fourteen were selected for meta-analysis of disclosure rates of biologically-based CM. Overall disclosure rates varied (7-80%). Meta-analysis revealed a 33% disclosure rate (95%CI: 24% to 43%) for biologically-based CM. Reasons for non-disclosure included lack of inquiry from medical providers, fear of provider disapproval, perception of disclosure as unimportant, belief providers lacked CM knowledge, lacking time, and belief CM was safe. Reasons for disclosure included inquiry from medical providers, belief providers would support CM use, belief disclosure was important for safety, and belief providers would give advice about CM. Disclosure appears to be influenced by the nature of patient-provider communication. However, inconsistent definitions of CM and lack of a standard measure for disclosure created substantial heterogeneity between studies. Disclosure of CM use to medical providers must be encouraged for safe, effective patient care.

Should postoperative haemoglobin and potassium levels be checked routinely following blood-conserving primary total joint arthroplasty?

AIMS

Despite declining frequency of blood transfusion and electrolyte supplementation following total joint arthroplasty, postoperative blood analyses are still routinely ordered for these patients. This study aimed to determine the rate of blood transfusion and electrolyte restoration in arthroplasty patients treated with a perioperative blood conservation protocol and to identify risk factors that would predict the need for transfusion and electrolyte supplementation.

PATIENTS AND METHODS

Patients undergoing primary total joint arthroplasty of the hip or knee between July 2016 and February 2017 at a single institution were included in the study. Standard preoperative and postoperative laboratory data were collected and reviewed retrospectively. A uniform blood conservation programme was implemented for all patients. Need for blood transfusion or potassium supplementation was determined through a coordinated decision by the care team. Rates of transfusion and supplementation were observed, and patient risk factors were noted.

RESULTS

The overall rate of blood transfusion was 1.06% in the study population of 1132 total joint arthroplasties performed in 1023 patients. Of the 12 patients requiring transfusion, 11 were female, ten occurred in patients undergoing total hip arthroplasty, and all 12 patients had a preoperative haemoglobin level less than 130 g/l. Operative duration and surgical blood loss were significantly greater in those patients requiring blood transfusion. Nearly all patients requiring transfusion had a history of, or risk factors for, cardiovascular disease. Potassium supplementation was required in 15.5% of the study cohort; 72% of these patients receiving potassium presented with a potassium level less than 4 mmol/l during preoperative testing, while the remaining 28% had a past medical history of either significant anaemia, cardiopulmonary, cardiovascular, or renal diseases that had required substantial medical management.

CONCLUSION

A consistent blood-conserving perioperative strategy effectively minimized need for blood transfusion in total joint arthroplasty patients below previously reported rates in the literature. We suggest that postoperative full blood counts and basic metabolic panels should not routinely be ordered in these patients unless their preoperative haemoglobin and potassium is below 130 g/dl or 4 mmol/l respectively, and they have medical comorbidities.

Knowledge of HIV pre-exposure prophylaxis among immigrant Asian gay men living in New Zealand

ABSTRACT INTRODUCTIONHIV pre-exposure prophylaxis (PrEP) is a new bio-medical means of reducing the risk of HIV infection. It’s use by individuals at high risk of HIV acquisition is recommended. AimsThis study identifies the ways immigrant Asian gay men living in New Zealand talk about and understand issues related to PrEP. METHODSA qualitative descriptive methodology was used. Individual interviews were conducted with 18 immigrant Asian gay men who were not users of PrEP. Participants were aged 21 – 36 years and one-third had arrived in New Zealand within 3 years of completing the interview. Data were analysed using thematic analysis. RESULTSThree themes evident across the men’s talk in relation to pre-exposure prophylaxis were identified: ‘I’m not sure what PrEP is’; ‘PrEP is not proven’; and ‘PrEP is for others, not me’. DISCUSSIONPrEP is necessary for working towards the elimination of HIV. To improve uptake among Asian gay men, improved literacy around HIV and pre-exposure prophylaxis is required. This knowledge needs to be improved at both the individual level in primary care services and collectively through health promotion initiatives. These services and health promotion initiatives need to be provided in ways that encourage engagement by Asian gay men.

"Engaging in my rural community": perceptions of people aged 85 years and over

PURPOSE

 Globally, numbers of people aged 85 years and over are increasing. Many older people, including those 85 years and over, are ageing in rural areas. For successful ageing in place, physical and social environments must be appropriate. The aim of this study is to understand the influence the physical and social environments have on enabling those aged 85 years and over to remain engaged in a rural community. Method: Utilizing an environmental gerontological approach, semi-structured interviews were undertaken with 15 people who lived independently in a rural community. Following transcription data were analyzed and themes identified. Results: Two themes were identified; "Negotiating the physical environment: 'Getting there and back'" and "Maintaining social networks: 'Places to go, people to see'". The findings provide insight into the importance of driving, parking close to amenities and negotiating the local environment to this group of older people and their ability to engage with their community. All participants agreed social engagement with friends, family or neighbors was important to them. Conclusion: These findings highlight the interconnection between physical and social environments. An enabling physical environment is essential to support social participation of people aged 85 years and over.

Associations between complementary medicine utilisation and the use of contraceptive methods: Results of a national cross-sectional survey

BACKGROUND AND PURPOSE

This study examines the relationship between the use of complementary medicine (CM) interventions or consultations with CM practitioners and women's choice of contraceptive method.

MATERIALS AND METHODS

A secondary analysis of a cross-sectional survey of Australian Women aged 34-39 years from the Australian Longitudinal Study on Women's Health (ALSWH) was conducted. Associations between use of CM and contraception were analysed using Chi-squared tests and multivariate logistic regression.

RESULTS

Based on the responses from the included women (n = 7299), women who consulted a naturopath/herbalist were less likely to use implant contraceptives (OR 0.56; 95% confidence interval (CI) 0.33; 0.95). Those consulting a chiropractor (OR 1.54; 95%CI 1.05; 2.25) or an osteopath (OR 2.16; 95% CI 1.32; 3.54) were more likely to use natural contraception.

CONCLUSION

There may be a link between women's choice of contraceptive method and their use of CM, in particular, with CM practitioner consultations.

Search for neutrinos from decaying dark matter with IceCube: IceCube Collaboration

With the observation of high-energy astrophysical neutrinos by the IceCube Neutrino Observatory, interest has risen in models of PeV-mass decaying dark matter particles to explain the observed flux. We present two dedicated experimental analyses to test this hypothesis. One analysis uses 6 years of IceCube data focusing on muon neutrino 'track' events from the Northern Hemisphere, while the second analysis uses 2 years of 'cascade' events from the full sky. Known background components and the hypothetical flux from unstable dark matter are fitted to the experimental data. Since no significant excess is observed in either analysis, lower limits on the lifetime of dark matter particles are derived: we obtain the strongest constraint to date, excluding lifetimes shorter than10 28 s at 90% CL for dark matter masses above 10 TeV .

A cumulative meta-analysis of the effects of individual physical activity interventions targeting healthy adults

Despite a large and increasing evidence base on physical activity interventions, the high rates of physical inactivity and associated chronic diseases are continuing to increase globally. The purpose of this cumulative meta-analysis was to investigate the evolution of randomized controlled trial evidence of individual-level physical activity interventions to asses if new trials are contributing novel evidence to the field. Through a two-staged search process, primary studies examining the effects of interventions targeted at increasing physical activity within healthy adult populations were pooled and selected from eligible systematic reviews. Cumulative meta-analyses were performed on effect sizes immediately post-intervention (n = 62), and for long-term behaviour change (≥12-month post-baseline; n = 27). Sufficiency and stability of the evidence was assessed through application of pre-published indicators. Meta-analyses suggest overall positive intervention effects on physical activity. The evidence base for effectiveness immediately post-intervention reached levels of sufficiency and stability in 2007; and for long-term follow-up in 2011. In the time since, intervention effectiveness has not substantially changed, and further trials are unlikely to change the direction and magnitude of effect. Substantial evidence exists demonstrating that physical activity interventions can modify individual behaviour in controlled settings. Researchers are urged to shift focus towards investigating the optimization, implementation, sustainability and cost-effectiveness of interventions.

Late-life living and care arrangements of older Filipino New Zealanders

AIMS AND OBJECTIVES

To explore the living and care arrangement plans of older Filipino immigrants in New Zealand.

BACKGROUND

New Zealand is rapidly becoming the host to an increasing number of ageing Filipino immigrants. Despite this sizeable population growth of ageing Filipinos in New Zealand, still very little is known about this ethnic group's care needs and living arrangement preferences in later life within the New Zealand context.

DESIGN

Qualitative descriptive approach.

METHODS

Data were collected from 15 older Filipinos who participated in face-to-face interviews. Data were analysed using a thematic analytical framework.

RESULTS

Two major themes were identified from the data analysis. The first theme "preferred living and care arrangements" is about older Filipinos' preferred plans for future residence and in receiving care when no longer able to function independently in their own homes. The second theme "negotiating readiness and acceptance" is about hypothetical situations that older Filipinos described and anticipated that will greatly facilitate their readiness and acceptance to living in aged care facilities.

CONCLUSION

The study results have implications for service delivery within the New Zealand residential aged care sector. Due to an increasing number of older Filipino immigrants requiring care, residential aged care facilities must ensure their care models meet the needs of this growing group of older people.

RELEVANCE TO CLINICAL PRACTICE

Nursing staff skill sets in the aged care sector require sensitivity to older immigrants' health needs without compromising cultural beliefs and practices while living in residential aged care facilities.

A Six-Channel Automated Platelet Aggregometer

A simple automated platelet aggregometer is described which allows six plasma samples to be handled concurrently.

Clinicopathological features of squamous cell carcinoma of the oral cavity and oropharynx in young patients

Our aim was to examine the clinicopathological features of squamous cell carcinoma (SCC) of the oral cavity and oropharynx in a group of young patients who were dignosed during a 15-year period (2000-2014). Patients' clinical details, risk factors, and survival were obtained from medical records. Formalin-fixed, paraffin-embedded, tissue was tested for high-risk human papillomavirus (HPV). The results were compared with those of a matching group of older patients. We identified 91 patients who were younger than 45 years old, and the 50 youngest patients were studied in detail. The male:female ratio was 2:1, with more tumours located in the oral cavity than in the oropharynx (35 compared with 15). HPV-related SCC was restricted to the oropharynx. When matched for site, stage and HPV status, five-year overall survival was similar in young and matched older patients (log-rank test, p=0.515). Our findings suggest that young patients with oral SCC have a disease profile similar to that of older patients with the condition. It is plausible that prognostic information generally available for oral cancers is applicable to young patients with the disease.

Loneliness in Men 60 Years and Over: The Association With Purpose in Life

Loneliness as a consequence of getting older negatively impacts on the health and well-being of men as they age. Having a purpose in life may mitigate loneliness and therefore positively impact on health and well-being. Limited research into loneliness and purpose in life has been undertaken in older men. This study seeks to understand the relationship between loneliness and purpose in life in a group of older men. Using data from a cross-sectional survey of 614 men aged 60 years and over living in New Zealand, bivariate and multivariate analyses were undertaken to examine the relationship between loneliness and purpose in life using a range of demographic, health, and social connection variables. Bivariate analysis revealed that being unpartnered and having low socioeconomic status, limited social networks, low levels of participation, and mental health issues were associated with loneliness. Multivariate analysis showed that having poor mental health and lower purpose in life were indicators of loneliness. Consequently, improving mental health and purpose in life are likely to reduce loneliness in at-risk older men. As older men are a heterogeneous group from a variety of sociocultural and ethnic backgrounds, a multidimensional approach to any intervention initiatives needs to occur.

Values in evaluation - The use of rubrics

Rubrics are used by evaluators who seek to move evaluations from being mere descriptions of an evaluand (i.e., the programme, project or policy to be evaluated) to determining the quality and success of the evaluand. However, a problem for evaluators interested in using rubrics is the literature relating to rubric development is scattered and mostly located in the education field with a particular focus on teaching and learning. In this short article we review and synthesise key points from the literature about rubrics to identify best practice. In addition we draw on our rubric teaching experience and our work with a range of stakeholders on a range of evaluation projects to develop evaluation criteria and rubrics. Our intention is to make this information readily available and to provide guidance to evaluators who wish to use rubrics to make value judgements as to the quality and success of evaluands.

Measurement of the ν μ energy spectrum with IceCube-79: IceCube Collaboration

IceCube is a neutrino observatory deployed in the glacial ice at the geographic South Pole. The ν μ energy unfolding described in this paper is based on data taken with IceCube in its 79-string configuration. A sample of muon neutrino charged-current interactions with a purity of 99.5% was selected by means of a multivariate classification process based on machine learning. The subsequent unfolding was performed using the software Truee. The resulting spectrum covers an E ν -range of more than four orders of magnitude from 125 GeV to 3.2 PeV. Compared to the Honda atmospheric neutrino flux model, the energy spectrum shows an excess of more than 1.9 σ in four adjacent bins for neutrino energies E ν ≥ 177.8 TeV . The obtained spectrum is fully compatible with previous measurements of the atmospheric neutrino flux and recent IceCube measurements of a flux of high-energy astrophysical neutrinos.

The value of local registry data for describing cervical cancer management and outcomes over three decades in Australia

Registry data on invasive cervical cancers (n = 1,274) from four major hospitals (1984-2012) were analysed to determine their value for informing local service delivery in Australia. The methodology comprised disease-specific survival analyses using Kaplan-Meier product-limit estimates and Cox proportional hazards models and treatment analyses using logistic regression. Five- and 10-year survivals were 72% and 68%, respectively, equating with relative survival estimates for Australia and the USA. Most common treatments were surgery and radiotherapy. Systemic therapies increased in recent years, generally with radiotherapy, but were less common for residents from less accessible areas. Surgery was more common for younger women and early-stage disease, and radiotherapy for older women and regional and more advanced disease. The proportion of glandular cancers increased in-step with national trends. Little evidence of variation in risk-adjusted survival presented over time or by Local Health District. The study illustrates the value of local registry data for describing local treatment and outcomes. They show the lower use of systemic therapies among residents of less accessible areas which warrants further investigation. Risk-adjusted treatment and outcomes did not vary by socio-economic status, suggesting equity in service delivery. These data are important for local evaluation and were not available from other sources.
