- Description: To assess the effect of midwife-led postpartum debriefing on psychological variables, 149 women were recruited in the third trimester of their pregnancy and were randomly assigned to treatment and control conditions. Women in the treatment group received midwife-led postpartum debriefing within 3 days postpartum, whereas women in the control group did not receive formalised debriefing. Background information and psychological variables were assessed in the prepartum, and birthing information was gathered 2 days postpartum. The psychological variables, plus a measure of birth trauma, were re-assessed at 1 month, and again, together with a measure of parenting stress, at 3 months postpartum. Although the majority of women reported positively on their debriefing experience, statistical analyses indicated that only on the measure of dyadic satisfaction was there some suggestion that debriefing was effective. There were no significant differences between the treatment and control groups on measures of personal information, depression, anxiety, trauma, perception of the birth, or parenting stress at any assessment points, postpartum. On the other hand, the effect of medical intervention on women's perceptions of their birthing was evident, with women who experienced more medical intervention reporting more negative perceptions of their birthing than women who had experienced less medical intervention. Surprisingly, this difference was more marked among the women who had been debriefed than among the control group. Generally, the results did not support midwife-led debriefing as an effective intervention postpartum. © 2006 Society for Reproductive and Infant Psychology.

- Description: This paper examines self-reported retrospective data for a 12 month period from 2038 adult cyclists from New South Wales (Australia), and compares cyclists according to whether they self-identify as riding mainly for transport or mainly for recreation. Statistically significant differences were found in the demographic characteristics, cycling patterns, and crash experiences between these two groups of cyclists. Transport cyclists tended to be younger, travel more days per week, and within morning and evening peak hours than recreational cyclists; recreational cyclists were more likely to identify fitness as a purpose for cycling. The proportion of cyclists experiencing a crash or crash-related injury in the previous 12 months was similar for transport and recreational cyclists, but there were differences in crash types and location which likely reflect different cycling environments. Heterogeneity within transport and recreational cyclists was also found, based on self-reported riding intensity. An understanding of the different cycling patterns and experiences of various types of cyclists is useful to inform road safety, transport and health promotion policy. © 2015 Elsevier Ltd.

- Description: This paper examines self-reported prospectively collected data from 2038 adult transport and recreational cyclists from New South Wales (Australia) to determine exposure-based incident crash and injury rates. During 25,971 days of cycling, 198 crashes were reported, comprising approximately equal numbers of falls and collisions. The overall crash rate was 0.290 (95% CI, 0.264-0.319) per 1000 km or 6.06 (95% CI, 5.52-6.65) per 1000 h of travel. The rate of crashes causing any injury (self-treated, or medically attended without overnight hospital stay) was 0.148 (95% CI, 0.133-0.164) per 1000 km or 3.09 (95% CI, 2.79-3.43) per 1000 h of travel. The rate of crashes causing a medically attended injury (without overnight hospital stay) was 0.023 (95% CI, 0.020-0.027) per 1000 km or 0.49 (95% CI, 0.43-0.56) per 1000 h of travel. No injuries requiring an overnight stay in hospital were reported on days meeting the inclusion criteria. After adjustment for exposure in hours, or for the risks associated with different infrastructure utilisation, the rates of crashes and medically attended injuries were found to be greater for females than males, less experienced than more experienced cyclists, and for those who rode mainly for transport rather than mainly for recreation. Comparison of estimated crash and injury rates on different infrastructure types were limited by the small number of events, however findings suggest that the separation of cyclists from motorised traffic is by itself not sufficient to ensure safe cycling. © 2015 Elsevier Ltd.

- Description: This paper investigates events in which cyclists perceive a cycling crash is narrowly avoided (henceforth, a near miss). A cohort of 2038 adult transport and recreational cyclists from New South Wales (Australia) provided self-reported prospectively collected data from cycling diaries to allow the calculation of an exposure-based rate of near misses and investigation of near miss circumstances. During 25,971 days of cycling, 3437 near misses were reported. For a given time cycling, cyclists who rode mainly for transport (compared with those who rode mainly for recreation), and cyclists with less experience (compared to those with more experience) were more likely to report a near miss; older cyclists (60+ years) were less likely to report a near miss than younger cyclists (25-59 years). Where type of near miss was recorded, 72.0% involved motor vehicles, 10.9% involved pedestrians and 6.9% involved other cyclists. Results indicate some similarities between near misses and crashes reported by this cohort during the same reporting period. A bias toward reporting near misses with motor Vehicles was suggested, which likely reflects cyclists' perceptions that crashes involving motor vehicles are particularly serious, and highlights their impact on perceived safety. Given the relative rarity of crashes, and the limited breadth and depth of administrative data, collection of near miss data may contribute to our understanding of cycling safety by increasing the volume and detail of information available for analysis. Addressing the causes of near misses may offer an opportunity to improve both perceived and actual safety for cyclists. (C) 2017 Elsevier Ltd. All rights reserved.

- Description: Riders cycling on roads without bicycle lanes are generally advised to ride in the centre of their lane (primary position), and to move toward the left of the lane (in left-hand traffic; secondary position) only to let faster traffic pass and when it is safe. The present research investigated which situational and personal characteristics were associated with choice of lane position, and whether choice of lane position is associated with on-road crash involvement. A large cohort of bicycle riders from New South Wales Australia reported on their cycling patterns and crashes in 6 reporting weeks over a 1-year period using on-line surveys. During one reporting week 1525 participants identified their preferred choice of lane position in each of 6 visually-depicted scenarios that were designed to investigate the influence of number of lanes (in the cyclists’ direction of travel), parked cars, and bus lanes. A majority of respondents preferred the secondary position in scenarios with a clear kerbside lane. Respondents were significantly more likely to choose the primary position in multiple-lane situations compared to single-lane situations, if there were parked cars in the kerbside lane, and if they were female, younger, experienced riders, transport riders, or high intensity riders. Controlling for personal characteristics, choosing the primary position in a single clear traffic lane scenario was associated with a higher on-road crash rate, while choosing the primary position in a traffic lane with parked cars scenario was associated with a lower on-road crash rate. Results suggested that when riding on-road the bicycle riders in this Australian cohort prefer to keep their distance from motorised traffic, allowing traffic to pass safely when space allows. Nonetheless, results suggested that choice of lane position is highly dependent on the local road and traffic environment. Further research is needed to support advice to cyclists.

- Description: Objectives: The burden of disease due to influenza B is often underestimated. Clinical studies have shown that oseltamivir, a widely used neuraminidase inhibitor (NAI) antiviral drug, may have reduced effectiveness against influenza B viruses. Therefore, it is important to study the effect of neuraminidase mutations in influenza B viruses that may further reduce NAI susceptibility, and to determine whether these mutations have the same effect in the two lineages of influenza B viruses that are currently circulating (B/Yamagata-like and B/Victoria-like). Methods: We characterized the effect of 16 amino acid substitutions across five framework residues and four monomeric interface residues on the susceptibility to four different NAIs (oseltamivir, zanamivir, peramivir and laninamivir). Results: Framework residue mutations E117A and E117G conferred highly reduced inhibition to three of the four NAIs, but substantially reduced neuraminidase activity, whereas other framework mutations retained a greater level of NA activity. Mutations E105K, P139S and G140R of the monomeric interface were also found to cause highly reduced inhibition, but, interestingly, their effect was substantially greater in a B/Victoria-like neuraminidase than in a B/Yamagata-like neuraminidase, with some susceptibility values being up to 1000-fold different between lineages. Conclusions: The frequency and the effect of key neuraminidase mutations on neuraminidase activity and NAI susceptibility can differ substantially between the two influenza B lineages. Therefore, future surveillance, analysis and interpretation of influenza B virus NAI susceptibility should consider the B lineage of the neuraminidase in the same manner as already occurs for different influenza A neuraminidase subtypes.

- Description: As the COVID-19 pandemic accelerates, one public health response has been for governments to impose quarantine ‘lockdowns’ which require people to socially isolate. In this study, we explored the level of psychological distress that people experienced in social isolation and the factors which might ameliorate or exacerbate it. Two hundred and thirteen participants (69% female) with a mean age of 37.82 years participated in an online study. They completed a series of questions designed as part of a larger cross-national study. A positive attitude towards social isolation introduced by government as a strategy to reduce the transmission of COVID-19 was predictive of positive coping strategies, and both attitude and coping predicted reduced psychological distress. Participants’ worries about contagion of COVID-19, their financial status, and the economic and political impact of the COVID-19 pandemic predicted increases in their psychological distress. Social support from family and work colleagues was not significant in reducing worries or psychological distress but it did positively predict engagement in coping. The findings and recommendations are discussed. Practitioner points: Fostering a positive attitude towards social isolation in clients: reduces psychological distress, fosters engagement in positive coping behaviours. Enhancing clients’ level of social support received will serve to increase positive coping and indirectly reduce psychological distress during social isolation. Strategies to reduce clients’ COVID-19 worries are important as worry contributes to their overall level of psychological distress. © 2020 The British Psychological Society

The second theme encompasses methodological and reporting issues, including differences between studies, inadequate statistical control of potential confounders, the under-reporting of effect sizes and the lack of consideration of clinical significance. The final theme covers differing approaches to studying cannabis use, including recruitment methods. Limitations related to the nature of the data collected by researchers are discussed throughout, with a focus on how they affect our understanding of cannabis use and users.

Here they practised many types of musical activity, including Chinese opera, songs, instrumental music, and music for ceremonial and religious occasions. Chinese musicians also participated in concerts and celebrations before the wider community. This article explores these different types of Chinese music, and looks at the role of music in the lives of the Chinese people who, because of the widespread discrimination they faced, were forced to live and work in an environment of prejudice and hostility.

- Description: Rattan agroforestry is an important land use system in Central Kalimantan, Indonesia, providing a wide range of products for subsistence communities. The ethnobotanical importance of rattan includes heritage values reflecting traditional ecological knowledge. This traditional forestry practice is consistent with necessary conservation of biodiversity and ecosystem services currently threatened by expansion of oil palm plantations. We examined species composition and morphology (including life stages) of vegetation associated with rattan agroforests in the Katingan district, Central Kalimantan. An examination of harvested rattan plots revealed 101 species of vegetation of which 90% are considered to be useful (food, construction materials, medicines) and most (97%) were native species, typical of lowland tropical forest vegetation. Vegetation in the rattan agroforests was dominated by trees (in terms of species richness). There were 80 species of trees, representing 79% of the plants surveyed. Vitex pubescens (kaluan) had the highest importance value as it occupied more space, was represented by more individuals and was most frequently found in rattan gardens. These trees in general have a relatively open canopy with strong branches; properties considered ideal to support rattan. Canopy forming species are actively managed to provide for growth of useful understory vegetation (including rattan) important in the livelihoods of village communities. Rattan agroforests also provide cultural services reflecting traditional use (e.g. a sense of belonging and ancestral linkages for local forest-dependent communities). The importance of ethnobotanical approaches to rattan cultivation includes the socio-economic evaluation of land use and the promotion of sustainable land use policies in Indonesia. This is important in the context of oil palm expansion which has a demonstrably adverse impact on ecosystem services. © 2019, Springer Nature B.V.

- Description: Surveillance data indicate that most circulating A(H1N1)pdm09 influenza viruses have remained antigenically similar since they emerged in humans in 2009. However, antigenic drift is likely to occur in the future in response to increasing population immunity induced by infection or vaccination. In this study, sequential passaging of A(H1N1)pdm09 virus by contact transmission through two independent series of suboptimally vaccinated ferrets resulted in selection of variant viruses with an amino acid substitution (N156K, H1 numbering without signal peptide; N159K, H3 numbering without signal peptide; N173K, H1 numbering from first methionine) in a known antigenic site of the viral HA. The N156K HA variant replicated and transmitted efficiently between naïve ferrets and outgrew wildtype virus in vivo in ferrets in the presence and absence of immune pressure. In vitro, in a range of cell culture systems, the N156K variant rapidly adapted, acquiring additional mutations in the viral HA that also potentially affected antigenic properties. The N156K escape mutant was antigenically distinct from wildtype virus as shown by binding of HA-specific antibodies. Glycan binding assays demonstrated the N156K escape mutant had altered receptor binding preferences compared to wildtype virus, which was supported by computational modeling predictions. The N156K substitution, and culture adaptations, have been detected in human A(H1N1)pdm09 viruses with N156K preferentially reported in sequences from original clinical samples rather than cultured isolates. This study demonstrates the ability of the A(H1N1)pdm09 virus to undergo rapid antigenic change to evade a low level vaccine response, while remaining fit in a ferret transmission model of immunization and infection. Furthermore, the potential changes in receptor binding properties that accompany antigenic changes highlight the importance of routine characterization of clinical samples in human A(H1N1)pdm09 influenza surveillance.

- Description: Background: Studies comparing internally linked (person–identifying) and unlinked (episodes of care) hospital discharge data (HDD) on hip fractures have mainly focused on incidence overestimation by unlinked HDD, but little is known about the impact of overestimation on patient profiles such as comorbidity estimates. In view of the continuing use of unlinked HDD in hip fracture research and the desire to apply research results to hip fracture prevention, we concurrently assessed the accuracy of both incidence and comorbidity estimates derived from unlinked HDD compared to those estimated from internally linked HDD. Methods: We analysed unlinked and internally linked HDD between 01 July 2005 and 30 June 2008, inclusive, from Victoria, Australia to estimate the incidence of hospital admission for fall-related hip fracture in community-dwelling older people aged 65+ years and determine the prevalence of comorbidity in patients. Community-dwelling status was defined as living in private residence, supported residential facilities or special accommodation but not in nursing homes. We defined internally linked HDD as the reference standard and calculated measures of accuracy of fall-related hip fracture incidence by unlinked HDD using standard definitions. The extent to which comorbidity prevalence estimates by unlinked HDD differed from those by the reference standard was assessed in absolute terms. Results: The sensitivity and specificity of a standard approach for estimating fall-related hip fracture incidence using unlinked HDD (i.e. omitting records of in-hospital deaths, inter-hospital transfers and readmissions within 30 days of discharge) were 94.4% and 97.5%, respectively. The standard approach and its variants underestimated the prevalence of some comorbidities and altered their ranking. The use of more stringent selection criteria led to major improvements in all measures of accuracy as well as overall and specific comorbidity estimates. Conclusions: This study strongly supports the use of linked rather than unlinked HDD in injury research. In health systems where linked HDD are unavailable, current approaches for identifying incident hip fractures may be enhanced by incorporating additional evidence-based criteria.

- Description: Little research has been undertaken into the barriers facing rural adolescents seeking help and support for mental health problems. This study presented students from rural secondary schools in Victoria with hypothetical scenarios of an adolescent living in a rural area with a mental disorder and posed questions inorder to create group discussion. The results revealed a range of perceived barriers to help-seeking that could be considered unique to rural settings. However, adolescents also expressed positive attitudes and identified a range of professional help sources available to them. The findings support recent moves towards providing school-based mental health services to young people in rural areas.

- Description: Background: Same-sex attracted young adults have been found to experience higher rates of mental health problems and greater difficulties in accessing specialist mental health care services compared to their heterosexual peers. Internet-based mental health interventions have the potential to be more engaging and accessible to young adults compared to those delivered face-to-face. However, they are rarely inclusive of lesbian women and gay men. Thus, the current study aims to evaluate the effectiveness of an online mental health and wellbeing program, Out & Online (http://www.outandonline.org.au), in comparison to a wait-list control group, for reducing anxiety and depressive symptoms in same-sex attracted young adults aged between 18 and 25 years. Methods/Design: We are recruiting, through media and community organisations, 200 same-sex attracted young adults with anxiety and/or depressive symptoms and mild to moderate psychological distress (Kessler-10 score between 16 to 21). Participants will be randomly allocated to the intervention (the online program) or the wait-list control group based on a permuted blocked randomisation method to allow for stratification by gender. Participants in the intervention group will receive a tailored program for up to three types of mental health difficulties simultaneously. The primary outcome of anxiety and/or depressive symptoms, and secondary outcomes related to psychological distress, wellbeing and health behaviour will be measured at pre-intervention (0 week), post-intervention (8 weeks) and at a 3-month follow-up (20 weeks). Discussion: This online mental health and wellbeing program will be one of the first online interventions to be designed specifically to be relevant for same-sex attracted individuals. If the program is found to be effective it will improve access to specialist same-sex attracted-relevant mental health services for young adults and will facilitate wellbeing outcomes for these individuals. This program will also be a significant development in the delivery of tailored interventions that target multiple types of mental health conditions simultaneously. © 2014 Abbott et al.

- Description: Objectives: Hospital discharge data (HDD) in many health systems do not capture the date of injury (DOI); the absence of this date hinders researchers’ ability to distinguish repeat from incident injury admissions. Various approaches using somewhat arbitrary criteria have been explored to increase the accuracy of incident injury identification. However, these approaches have not been validated against a data source which contains DOI. The aim of this study was to determine the accuracy of evidence-based criteria for identifying fall-related incident hip fractures in the absence of DOI using HDD containing DOI as the reference standard. Design: Retrospective database study. Setting: New Zealand. Participants: 8761 patients aged 65+ years admitted for fall-related hip fracture between 1 July 2005 and 30 June 2008, inclusive. Outcome measures: We defined person-identifying HDD containing DOI as the reference standard and calculated measures of the accuracy of evidence-based criteria for identifying fall-related incident hip fractures from HDD not containing DOI. The criteria were principal diagnosis of hip fracture, mechanism of injury indicating a fall, admission type emergency, admission source other than a transfer and presence of hip operation code(s). For a subsequent fall-related hip fracture, additional criteria were time between successive hip fractures ≥120 days, and all external cause-of-injury codes being different to those for the previous hip fracture. Results: The sensitivity and specificity of the criteria for identifying fall-related incident hip fractures from data not containing DOI were 96.7% and 99.3%, respectively, compared with the reference standard. The application of these criteria resulted in a slight underestimation of the percentage of patients with multiple hip fractures. Conclusions: Although it is preferable to have DOI; this study demonstrates that evidence-based criteria can be used to reliably identify fall-related incident hip fractures from the person-identifying HDD when DOI is unavailable.

- Description: This article surveys the development of the theory of compact groups and pro-Lie groups, contextualizing the major achievements over 125 years and focusing on some progress in the last quarter century. It begins with developments in the 18th and 19th centuries. Next is from Hilbert’s Fifth Problem in 1900 to its solution in 1952 by Montgomery, Zippin, and Gleason and Yamabe’s important structure theorem on almost connected locally compact groups. This half century included profound contributions by Weyl and Peter, Haar, Pontryagin, van Kampen, Weil, and Iwasawa. The focus in the last quarter century has been structure theory, largely resulting from extending Lie Theory to compact groups and then to pro-Lie groups, which are projective limits of finite-dimensional Lie groups. The category of pro-Lie groups is the smallest complete category containing Lie groups and includes all compact groups, locally compact abelian groups, and connected locally compact groups. Amongst the structure theorems is that each almost connected pro-Lie group G is homeomorphic to RI × C for a suitable set I and some compact subgroup C. Finally, there is a perfect generalization to compact groups G of the age-old natural duality of the group algebra R[G] of a finite group G to its representation algebra R(G, R), via the natural duality of the topological vector space RI to the vector space R(I), for any set I, thus opening a new approach to the Hochschild-Tannaka duality of compact groups. © 2021 by the authors.

- Description: Recent research indicates that rural Australian adolescents experience a number of barriers to their health, and in particular, their sexual health. Consequently, the present study aimed to examine levels of sexual health knowledge, sexual activity, condom use and attitudes towards condoms in a rural, adolescent population. In addition, the research tested a comprehensive model of condom use. One hundred and thirty six 15 to 19 year old students, 51 males (M age = 16.75, SD =.74 ) and 85 females (M age = 16.73, SD = .85), from schools in five towns of population not more than 6000 residents completed a survey package that included demographic information, a Sexual Health Knowledge Scale, the Condom Attitudes Scale and the Adolescent and Young Adult contraceptive Self-efficacy Scale. Results indicated that overall knowledge levels were low, with males knowing significantly less than females. Sixty-five percent of the participants had engaged in sexual intercourse, with over half of those reporting being inconsistent users or non-users of condoms. Within the context of the model, knowledge, attitudes, self-efficacy and intention to use condoms, all contributed to predicting condom use. Results suggest that rural adolescents require education and assistance to obtain and use condoms in a non-threatening environment.
