Background The coronavirus (COVID-19) pandemic has resulted in changes to the working arrangements of millions of employees who are now based at home and may continue to work at home, in some capacity, for the foreseeable future. Decisions on how to promote employees’ health whilst working at home (WAH) need to be based on the best available evidence to optimise worker outcomes. The aim of this rapid review was to review the impact of WAH on individual workers’ mental and physical health, and determine any gender difference, to develop recommendations for employers and employees to optimise workers’ health. Method A search was undertaken in three databases, PsychInfo, ProQuest, and Web of Science, from 2007 to May 2020. Selection criteria included studies which involved employees who regularly worked at home, and specifically reported on physical or mental health-related outcomes. Two review authors independently screened studies for inclusion, one author extracted data and conducted risk of bias assessments with review by a second author. Results Twenty-three papers meet the selection criteria for this review. Ten health outcomes were reported: pain, self-reported health, safety, well-being, stress, depression, fatigue, quality of life, strain and happiness. The impact on health outcomes was strongly influenced by the degree of organisational support available to employees, colleague support, social connectedness (outside of work), and levels of work to family conflict. Overall, women were less likely to experience improved health outcomes when WAH. Conclusions This review identified several health outcomes affected by WAH. The health/work relationship is complex and requires consideration of broader system factors to optimise the effects of WAH on workers’ health. It is likely mandated WAH will continue to some degree for the foreseeable future; organisations will need to implement formalised WAH policies that consider work-home boundary management support, role clarity, workload, performance indicators, technical support, facilitation of co-worker networking, and training for managers.

Poor quality jobs can impact employees’ health and wellbeing. However, jobs’ changing natures and employees’ increasing diversity mean extant job quality models may inadequately explain employees’ experiences. This qualitative case-study of an Australian organisation aimed to understand mothers’, fathers’ and childless women’s and men’s experiences of qualitative job demands, resources and rewards in the context of multilevel power relations. We used a critical feminist grounded theory approach to analyse 47 employees’ open-ended questionnaire responses and 10 employees’ in-depth interviews. Findings suggested participants had nuanced gendered, classed and aged experiences of qualitative job demands, resources and rewards, emanating from the societally-entrenched organisational growth imperative and mechanisms, and participants’ organisationally and societally-embedded individual, household and community contexts. The study enriches and expands job quality dimensions by suggesting job quality encompasses navigating between personal needs and abilities, and intrinsic task demands, resources and rewards; working (in)authentically within organisational contexts; working with others; and dealing with company change. Plain language summary Qualitative job demands among mothers, fathers and childless women and men in an Australian organisation This qualitative study of one Australian organisation aimed to understand mothers’, fathers' and childless women’s and men’s experiences of qualitative job demands, resources and rewards in their individual, household, community, organisational and societal contexts that are influenced at all levels by gender, class and age stereotypes. We analysed 47 employees’ open-ended questionnaire responses and 10 employees’ in-depth interviews. Findings suggested participants had nuanced gendered, classed and aged experiences of qualitative job demands, resources and rewards, emanating from participants’ interacting societal, organisational, community, household and individual contexts. The study suggests job quality includes navigating between personal needs and abilities, and job demands, resources and rewards; working authentically or inauthentically within organisational contexts; working with others; and dealing with company change. The study was limited by the small number of participants and their relatively similar characteristics. However, the findings are important for understanding nuanced experiences of job quality and their multiple levels of influence, and developing strategies to improve job quality for employees with different backgrounds and life contexts.

In 1964, Refsdal hypothesized that a supernova whose light traversed multiple paths around a strong gravitational lens could be used to measure the rate of cosmic expansion. We report the discovery of such a system. In Hubble Space Telescope imaging, we have found four images of a single supernova forming an Einstein cross configuration around a redshift z = 0.54 elliptical galaxy in the MACS J1149.6+2223 cluster. The cluster's gravitational potential also creates multiple images of the z = 1.49 spiral supernova host galaxy, and a future appearance of the supernova elsewhere in the cluster field is expected. The magnifications and staggered arrivals of the supernova images probe the cosmic expansion rate, as well as the distribution of matter in the galaxy and cluster lenses.

We identify minimal observing cadence requirements that enable photometric astronomical surveys to detect and recognize fast and explosive transients and fast transient features. Observations in two different filters within a short time window (e.g., g-and-i, or r-and-z, within <0.5 hr) and a repeat of one of those filters with a longer time window (e.g., >1.5 hr) are desirable for this purpose. Such an observing strategy delivers both the color and light curve evolution of transients on the same night. This allows the identification and initial characterization of fast transient-or fast features of longer timescale transients-such as rapidly declining supernovae, kilonovae, and the signatures of SN ejecta interacting with binary companion stars or circumstellar material. Some of these extragalactic transients are intrinsically rare and generally all hard to find, thus upcoming surveys like the Large Synoptic Survey Telescope (LSST) could dramatically improve our understanding of their origin and properties. We colloquially refer to such a strategy implementation for the LSST as the Presto-Color strategy (rapid-color). This cadence's minimal requirements allow for overall optimization of a survey for other science goals.

To evaluate the frequency of errors in the diagnosis of medical laboratory-diagnosed Chikungunya virus (CHIKV) infections in Australia, we studied 42 laboratory-diagnosed CHIKV serum samples from one Queensland medical laboratory by ELISA IgG/IgM and measured the specific neutralization antibodies (Nab) against Barmah Forest virus (BFV), CHIKV and Ross River virus (RRV). The sero-positivity rates for the sera were as follows: anti-BFV IgG+ 19% (8/42), IgM+ 2.4% (1/42) and Nab+ 16.7% (7/42); anti-CHIKV IgG+ 90.5% (38/42), IgM+ 21.4% (9/42) and Nab+ 90.5% (38/42); anti-RRV IgG+ 88.1% (37/42), IgM+ 28.6% (12/42) and Nab+ 83.2% (35/42), respectively. Among the samples with multiple antibody positivity, 2.4% (1/42) showed triple ELISA IgM+, and 14.3% (6/42) exhibited double IgM RRV+CHIKV+; 9.5% (4/42) showed triple IgG+, 76.2% (32/42) displayed double IgG RRV+CHIKV+, 4.8% (2/42) showed IgG BFV+RRV+ and 4.8% (2/42) showed IgG BFV++CHIKV+; and 9.5% (4/42) showed triple Nab+ and 69% (29/42) exhibited double Nab RRV+CHIKV+, respectively. Our analysis of the single-virus infection control Nab results suggested no cross-neutralization between RRV and BFV, and only mild cross-neutralization between CHIKV and RRV, BFV and CHIKV, all with a ≥4-fold Nab titre ratio difference between the true virus infection and cross-reactivity counterpart virus. Subsequently, we re-diagnosed these 42 patients as 1 BFV+, 8 CHIKV+ and 23 RRV+ single-virus infections, along with five RRV+/BFV+ and four RRV+/CHIKV+ double infections, and one possible RRV+/BFV+ or RRV+CHIKV+, respectively. These findings suggests that a substantial proportion of medically attended RRV and BFV infections were misdiagnosed as CHIKV infections, highlighting the imperative need for diagnostic laboratory tests capable of distinguishing between CHIKV infections and actively co-circulating RRV and BFV. For a correct diagnosis, it is crucial to consider reliable diagnostic methods such as the neutralization assay to exclude RRV and BFV.

ObjectivesTo investigate the impacts, on mental and physical health, of a mandatory shift to working from home during the COVID-19 pandemic.DesignCross sectional, online survey.SettingOnline survey was conducted from September 2020 to November 2020 in the general population.ParticipantsAustralian residents working from home for at least 2 days a week at some time in 2020 during the COVID-19 pandemic.Main outcome measuresDemographics, caring responsibilities, working from home arrangements, work-related technology, work–family interface, psychosocial and physical working conditions, and reported stress and musculoskeletal pain.Results924 Australians responded to the online questionnaire. Respondents were mostly women (75.5%) based in Victoria (83.7%) and employed in the education and training and healthcare sectors. Approximately 70% of respondents worked five or more days from home, with only 60% having a dedicated workstation in an uninterrupted space. Over 70% of all respondents reported experiencing musculoskeletal pain or discomfort. Gendered differences were observed; men reported higher levels of family to work conflict (3.16±1.52 to 2.94±1.59, p=0.031), and lower levels of recognition for their work (3.75±1.03 to 3.96±1.06, p=0.004), compared with women. For women, stress (2.94±0.92 to 2.66±0.88, p<0.001) and neck/shoulder pain (4.50±2.90 to 3.51±2.84, p<0.001) were higher than men and they also reported more concerns about their job security than men (3.01±1.33 to 2.78±1.40, p=0.043).ConclusionsPreliminary evidence from the current study suggests that working from home may impact employees’ physical and mental health, and that this impact is likely to be gendered. Although further analysis is required, these data provide insights into further research opportunities needed to assist employers in optimising working from home conditions and reduce the potential negative physical and mental health impacts on their employees.

Observations of an event (several energetic eruptions leading to a terminal explosion that is surprisingly hydrogen-rich) with the spectrum of a supernova do not match with other observations of supernovae. A very unusual supernova Thousands of 'core-collapse' supernovae have been observed over the past 15 years, with common observational elements such as hydrogen absorption lines that slow over time and a single light-curve peak or luminosity that plateaus for around 100 days before declining. Iair Arcavi and colleagues report observations of the supernova iPTF14hls, which does not display the usual elements. Its light curve has multiple peaks and extends over 600 days. They conclude that the properties could be explained by ejection of several tens of solar masses of gas a few hundred days before the explosion, but there is no viable explanation for how this occurred. Although multiple pre-supernova eruptions are predicted by the pulsational pair instability, that model is inconsistent with the energetics involved here and the continued presence of hydrogen absorption lines with no decrease in velocity. Every supernova so far observed has been considered to be the terminal explosion of a star. Moreover, all supernovae with absorption lines in their spectra show those lines decreasing in velocity over time, as the ejecta expand and thin, revealing slower-moving material that was previously hidden. In addition, every supernova that exhibits the absorption lines of hydrogen has one main light-curve peak, or a plateau in luminosity, lasting approximately 100 days before declining 1 . Here we report observations of iPTF14hls, an event that has spectra identical to a hydrogen-rich core-collapse supernova, but characteristics that differ extensively from those of known supernovae. The light curve has at least five peaks and remains bright for more than 600 days; the absorption lines show little to no decrease in velocity; and the radius of the line-forming region is more than an order of magnitude bigger than the radius of the photosphere derived from the continuum emission. These characteristics are consistent with a shell of several tens of solar masses ejected by the progenitor star at supernova-level energies a few hundred days before a terminal explosion. Another possible eruption was recorded at the same position in 1954. Multiple energetic pre-supernova eruptions are expected to occur in stars of 95 to 130 solar masses, which experience the pulsational pair instability 2 , 3 , 4 , 5 . That model, however, does not account for the continued presence of hydrogen, or the energetics observed here. Another mechanism for the violent ejection of mass in massive stars may be required.

Background The COVID 19 pandemic resulted in the introduction of public health measures including mandated and recommended work from home orders to reduce transmission. This provided a unique opportunity to examine sense of community and social support within the workplace and self-rated general health. This paper examines employees’ workplace sense of community and social support across one year of the COVID 19 pandemic and associated self-rated general health. Methods Analysis of longitudinal data (October 2020, May 2021, and November 2021) from the Employees Working from Home study conducted in Victoria, Australia during the COVID 19 pandemic was undertaken. Trajectory analyses were used to describe workplace sense of community and social support over time. Multinomial logistic regression was used to determine the associations between demographics, gender, caring responsibilities, and group membership based on the Growth Mixture Modelling. Generalised Mixed Models were used to measure effects of sense of community and social support on self-rated health. Results Increasing sense of community and social support in the workplace resulted in increased self-rated health. Trajectory analysis found two stable and distinct groups for sense of community. Social support varied with time; however, trajectory membership was not dependent on gender or caring responsibilities and had no relationship with return to the office. Conclusion Sense of community and social support in the workplace are important determinants of employees’ health, and as such, workplace strategies to improve sense of community and social support are required not only for employees working from home, but also those who have returned to the office, particularly as hybrid work arrangements become more common.

Background Ten per cent of women of reproductive age suffer from endometriosis, a painful and incurable disease that leaves women with severe implications for their health and overall well-being. Due to the absence of a cure and the limited effectiveness of available treatments, acquiring accurate information is paramount for women to successfully navigate both their daily lives and the complexities of the healthcare system. This scoping review aimed to map the current literature on women with endometriosis information needs, their information seeking behaviour, and the format and scope of current information resources available. Methods The scoping review was conducted using the JBI methodology for scoping reviews and reported according to the PRISMA-ScR statement. The final search was conducted in August 2024, through the databases Medline, Cinahl, Embase, Scopus, and WebofScience. Studies on information resources on endometriosis and information seeking behaviour as well as information needs of women with endometriosis were eligible for inclusion. Results The majority of the 25 included studies focused on information resources, specifically webpages and social media sites. While few studies analysed information seeking behaviour and information needs, the evidence shows women’s high interest in a broad spectrum of information topics. Across all studies, the internet was the most important access point for information. Conclusion Addressing the absence of systematic analyses on the information seeking behaviour and needs of women with endometriosis is crucial for future research. This step is essential for the development of customised information resources that cater specifically to the diverse needs of women affected by endometriosis.
