RESUMO

OBJECTIVES: In this paper, we use a UK case study to explore how the COVID-19 pandemic affected the mental health (emotional, psychological, social wellbeing) of farmers. We outline the drivers of poor farming mental health, the manifold impacts of the pandemic at a time of policy and environmental change, and identify lessons that can be learned to develop resilience in farming communities against future shocks. METHODS: We undertook a survey answered by 207 farmers across the UK, focusing on drivers of poor mental health and the effect of the COVID-19 pandemic. We also conducted 22 in-depth interviews with individuals in England, Scotland and Wales who provide mental health support to farmers. These explored how and why the COVID-19 pandemic affected the mental health of farmers. These interviews were supplemented by 93 survey responses from a similar group of support providers (UK-wide). RESULTS: We found that the pandemic exacerbated underlying drivers of poor mental health and wellbeing in farming communities. 67% of farmers surveyed reported feeling more stressed, 63% felt more anxious, 38% felt more depressed, and 12% felt more suicidal. The primary drivers of poor mental health identified by farmers during the pandemic included decreased social contact and loneliness, issues with the general public on private land, and moving online for social events. Support providers also highlighted relationship and financial issues, illness, and government inspections as drivers of poor mental health. Some farmers, conversely, outlined positive impacts of the pandemic. CONCLUSION: The COVID-19 pandemic is just one of many potential stressors associated with poor farming mental health and its impacts are likely to be long-lasting and delayed. Multiple stressors affecting farmers at the same time can create a tipping point. Therefore, there is a need for long-term support and ongoing evaluation of the drivers of poor mental health in farming families.

RESUMO

OBJECTIVE: To examine the experiences, needs, and perceptions of health professionals(HPs) treating women diagnosed with cancer during pregnancy(gestational cancer, GC). METHODS: Interviews were undertaken with Australian HPs who had treated women diagnosed with GC over the previous five years. HPs were recruited via social media, and professional and community networks. Questions focussed upon HPs' confidence caring for these women, whether current guidelines/training met their needs, psychological impacts of care provision, and service gaps. Interview data were analysed thematically. RESULTS: Twenty-seven HPs were interviewed; most were oncology HPs(22/27) with experience caring for women with gestational breast cancer and 13 had a breast-specific clinical focus (e.g. breast surgeon). Many were currently treating women with GC(48%) or had in the last 6-12 months(29.6%). Four themes were identified: A clinically complex case, Managing multi-disciplinary care, Centralised resources for health professionals, and Liaison, information and shared experiences for women. HPs found this population personally challenging to treat. They reported initial uncertainty regarding treatment due to infrequent exposure to GC, limited resources/information, and the need to collaborate with services with which they did not usually engage. Solutions offered include centralised resources, clinical liaison/care coordinators, and connecting women with GC with peer support. CONCLUSIONS: HPs perceived women with GC as a vulnerable, complex population and experienced challenges providing comprehensive care; particularly when treatment was delivered at geographically separated hospitals. Systemic changes are needed to optimise comprehensive care for these women. Their insights can guide the development of more integrated cancer and obstetric care, and better HP support.

RESUMO

Ovarian cancer (OC) can significantly impact sexual functioning beyond initial treatment and into survivorship. However, research suggests that the information and advice women want on this topic may not be readily provided by health professionals (HPs). We explored the psychological and sexual wellbeing of a sample of Australian women diagnosed with OC, to inform the development of effective, targeted sexuality resources. This paper presents a subset of our findings. Participants were recruited nationwide via social media, print advertisement and the database of a support organisation, Ovarian Cancer Australia. Self-reported demographic and clinical survey data were collected including perceptions of the availability and adequacy of sexuality support post-OC. Participants (n = 98) were on average 52.8 years old and 5.5 years post-diagnosis. A minority (22%) reported that the impact of OC on their sexuality was discussed by HPs; and 46% were satisfied with that discussion. Approximately half (52%) had wanted to discuss sexuality concerns with a HP during treatment and 43% still felt the need for this discussion. Open-ended responses revealed the need for more information that was detailed and specified what to expect post-diagnosis. Shortcomings of HPs in addressing sexuality were also revealed. This research provides further evidence that sexual health remains inadequately addressed in OC care across the trajectory for the majority of women, and is an area of unmet need.

RESUMO

Women diagnosed with cancer during pregnancy (gestational cancer) are a small but vulnerable population, with experts suggesting they require greater psycho-social support than either other women with cancer or other pregnant women. However, information on their psychological needs remains sparse. This commentary describes our work exploring the psychological needs of women diagnosed with gestational cancer, areas of unmet need we identified, and our recommendations for future programs and research. We conducted in-depth, semi-structured interviews with 23 Australian women diagnosed with gestational cancer in the preceding 5 years. Our findings depicted a group of women for whom cancer diagnosis and treatment had resulted in a sense of isolation and loneliness. Women reported seeking tailored information about their condition and treatments as well as one-on-one peer support with other gestational cancer survivors, which was challenging for them to access and which existing services struggled to provide. To address these unmet needs, innovative solutions may be necessary. Technology has the potential to connect and match women with one-to-one peer support, and research exploring the efficacy and acceptability of such interventions is required. Creative solutions, such as virtual resource hubs monitored or moderated by experts, would potentially meet the information needs of this group. However, as gestational cancer is relatively rare, the development and evaluation of such interventions would require a collaborative effort across multiple sites, as well as international collaboration and data pooling.

RESUMO

OBJECTIVES: To identify features enhancing the quality of healthcare experiences for women with gestational cancer, and explore the impact of the heterogeneous Australian healthcare system on those experiences. METHODS: Semi-structured, qualitative interviews were conducted with women diagnosed with any cancer during pregnancy in the last five years. Recruitment occurred during 2018-2019 via social media and professional, clinical and community networks. Questions related to women's experiences of their healthcare, wellbeing and psychosocial needs. Interviews were analysed thematically. RESULTS: Study participants (n = 23) received treatment in the private sector (n = 10), public sector (n = 8), or both (n = 5). Five interview themes were found: Control over healthcare; Trust in clinicians, hospitals and systems; Coordination of care; An uncommon diagnosis; Holistic, future-oriented care. Women were most likely to have had a positive healthcare experience when (a)care was well-coordinated and adjusted to meet their unique needs/challenges, and (b)women perceived their care went beyond their immediate medical needs and encompassed future psychosocial wellbeing, including preparation for postpartum challenges. CONCLUSION: Existing 'usual care' in the public and/or private sector for both the pregnancy and the cancer is insufficient to meet these women's needs. Prioritising psychological wellbeing including psychosocial needs, and communication and planning around fertility and postnatal challenges are essential for this population.

RESUMO

The Environmental Protection Agency (EPA) in Ireland is responsible for the ecological monitoring and assessment of 37 hydrometric areas covering 46 river catchments and over 13,000 km of river channel nationwide. The national river monitoring program commenced in 1971 and has developed further since 2007 into the National Rivers Water Framework Directive (WFD) Monitoring Program following the implementation of the WFD across the European Union. The monitoring program is designed to obtain sufficiently representative information to assess ecological quality for each water body assessed. Consequently, macroinvertebrate data have been collected at over 2,900 river survey stations on a minimum 3-year cycle to fulfil these requirements. While the EPA has collected these data for water quality assessments we recognize that the data have value beyond this one purpose. We provide a summary of how these 10,987 data records, covering the years 2007 to 2018, have been collected and used to deepen understanding of water quality, biodiversity and general ecological health of Ireland's river network.

RESUMO

BACKGROUND: Survivorship care plans (SCPs) have been used to address ongoing health problems associated with the diagnosis and treatment of early-stage breast cancer. OBJECTIVES: The aim of this article was to determine whether nurse-led consultations using SCPs, as compared with a standard medical consultation, identify more side effects and supportive care needs and lead to appropriate referral patterns. METHODS: The study audited 160 retrospective medical clinic and nursing SCP records in a sample of patients receiving treatment for early-stage breast cancer at a tertiary-level breast service in Australia. FINDINGS: Breast care nurses (BCNs) undertaking SCPs at a nurse-led consultation were significantly more likely than physicians to record symptoms related to menopausal/hormonal therapy, psychosocial/mental health, lifestyle, bone health, and sexuality. BCNs were also significantly more likely to refer patients for concerns related to psychosocial/mental health, lifestyle, and sexuality.

RESUMO

BACKGROUND: Women with breast cancer experience a significantly higher prevalence of sleep disturbance and insomnia than the general population. The experience of persistent sleep disturbance places these women at a higher risk of psychological and physical morbidity and a reduced quality of life. Treatment for sleep in this population is not part of routine care and is often managed inadequately. This randomised controlled trial will examine the combined effects of cognitive behavioural therapy (CBT) and bright light therapy (BLT) on the symptoms of insomnia, fatigue and mental health. METHOD/DESIGN: Women diagnosed with breast cancer who receive intravenous chemotherapy treatment at a quaternary referral metropolitan cancer centre in Melbourne, Australia, will be recruited. Recruitment will occur after diagnosis and prior to completion of chemotherapy. Eligible women will be randomised to the combined CBT and BLT intervention (CBT+) or relaxation audio-enhanced treatment as usual (TAU+). The CBT+ group will receive one face-to-face session on sleep strategies, one subsequent telephone call, and seven email packages containing CBT-based information and strategies. CBT+ participants will also wear Luminette® light glasses for 20 min each morning for the 6-week duration of the intervention. Women in TAU+ will receive two relaxation audio tracks via email. Outcomes will be measured at multiple points throughout the 6 weeks. Primary outcomes will be symptoms of insomnia and sleep efficiency, measured using the Insomnia Severity Index and a self-reported sleep diary. Secondary outcomes include objective measures of sleep assessed using the ActiGraph wGT3X-BT, and sleep-related complaints, fatigue and mental health, all assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS). Data will also be collected on potential treatment moderators and mechanisms and adherence to treatment. There will be 3-month follow-up measurements of insomnia symptoms, fatigue, sleep-related impairment, sleep disturbance, depression and anxiety. DISCUSSION: This is the first randomised controlled trial to combine CBT and BLT for the treatment of sleep disturbance in women with breast cancer. This novel design addresses the multiple causal factors for sleep complaints in this population. Results from this trial will advance knowledge in this field and may have important clinical implications for how best to treat sleep disturbance and insomnia in this population. If effective, the largely email-based format of the intervention would allow for relatively easy translation.

RESUMO

Wildlife conservation and the management of human-wildlife conflicts require cost-effective methods of monitoring wild animal behavior. Still and video camera surveillance can generate enormous quantities of data, which is laborious and expensive to screen for the species of interest. In the present study, we describe a state-of-the-art, deep learning approach for automatically identifying and isolating species-specific activity from still images and video data.We used a dataset consisting of 8,368 images of wild and domestic animals in farm buildings, and we developed an approach firstly to distinguish badgers from other species (binary classification) and secondly to distinguish each of six animal species (multiclassification). We focused on binary classification of badgers first because such a tool would be relevant to efforts to manage Mycobacterium bovis (the cause of bovine tuberculosis) transmission between badgers and cattle.We used two deep learning frameworks for automatic image recognition. They achieved high accuracies, in the order of 98.05% for binary classification and 90.32% for multiclassification. Based on the deep learning framework, a detection process was also developed for identifying animals of interest in video footage, which to our knowledge is the first application for this purpose.The algorithms developed here have wide applications in wildlife monitoring where large quantities of visual data require screening for certain species.

RESUMO

Bovine tuberculosis (bTB) is an epidemiologically, politically, and socially complex disease. Across multiple international contexts, policy makers have struggled to balance the competing demands of wildlife and agricultural interests in their efforts to create workable and effective disease management strategies. This paper draws comparative lessons between the cases of Michigan in the USA and the UK to exemplify some of the challenges of developing an effective strategy for the long-term control of endemic disease, particularly reflecting on efforts to "responsibilise" cattle producers and engage them in proactive activities to mitigate transmission risks on their own farms. Using qualitative data derived from 22 stakeholder interviews, it is argued that the management of bTB in Michigan has important lessons for the UK on the role of human dimensions in influencing the direction of disease control. The management of endemic bTB relies on the actions of individuals to minimise risk and, in contrast to the predominantly voluntary approach pursued in the UK, Michigan has shifted the emphasis towards obtaining producer support for wildlife risk mitigation and biosecurity via a mix of regulatory, fiscal, and social interventions. Whilst the scale of the bTB challenge differs between these two contexts, analysis of the different ideological bases for selecting management approaches offers interesting insights on the role of negotiated outcomes in attempts to adaptively manage a disease that is characterised by complexity and uncertainty.

RESUMO

CONTEXT: Public health leaders play pivotal roles in ensuring the population health for our nation. Since 2000, the number of schools of public health has almost doubled. The scholarly credentials for leaders of public health in academic and practice are important, as they make decisions that shape the future public health workforce and important public health policies. OBJECTIVE: This research brief describes the educational degrees of deans of schools of public health and state health directors, as well as their demographic profiles, providing important information for future public health leadership planning. DESIGN: Data were extracted from a database containing information obtained from multiple Web sites including academic institution Web sites and state government Web sites. Variables describe 2 sets of public health leaders: academic deans of schools of public health and state health directors. RESULTS: Deans of schools of public health were 73% males and 27% females; the PhD degree was held by 40% deans, and the MD degree by 33% deans. Seventy percent of deans obtained their terminal degree more than 35 years ago. State health directors were 60% males and 40% females. Sixty percent of state health directors had an MD degree, 4% a PhD degree, and 26% no terminal degree at all. Sixty-four percent of state health directors received their terminal degree more than 25 years ago. In addition to terminal degrees, 56% of deans and 40% of state health directors held MPH degrees. CONCLUSION: The findings call into question competencies needed by future public health professionals and leadership and the need to clarify further the level of public health training and degree type that should be required for leadership qualifications in public health.

RESUMO

OBJECTIVE: To develop a simple, cost-effective method for determining the size and geographic distribution of medically fragile (MF) individuals at risk from tropical storm surges for use by emergency management planners. DESIGN: The study used Geographic Information System (GIS) spatially referenced layers based on secondary data sources from both state and federal levels. SETTING: The study setting included the eastern North Carolina coastal counties that would be affected by tropical storm surges. SUBJECTS: The initial MF population was extrapolated from national estimates for five conditions and then applied to US Census block population. These conditions included insulin dependent diabetes, chronic obstructive pulmonary disease, congestive heart failure, end stage renal disease, and patients receiving long-term oxygen treatment. MAIN OUTCOMES: The main outcome of this study was a series of local and regional maps that portrayed the geographic distribution and estimated counts of potentially at-risk MF population from a tropical storm surge scenario. CONCLUSIONS: Maps depicting the geographic distribution and potential numbers of MF individuals are important information for planning and preparedness in emergency management and potentially engaging the public.

RESUMO

Plant diseases threaten both food security and the botanical diversity of natural ecosystems. Substantial research effort is focused on pathogen detection and control, with detailed risk management available for many plant diseases. Risk can be assessed using analytical techniques that account for disease pressure both spatially and temporally. We suggest that such technical assessments of disease risk may not provide an adequate guide to the strategies undertaken by growers and government to manage plant disease. Instead, risk-management strategies need to account more fully for intuitive and normative responses that act to balance conflicting interests between stakeholder organizations concerned with plant diseases within the managed and natural environments. Modes of effective engagement between policy makers and stakeholders are explored in the paper, together with an assessment of such engagement in two case studies of contemporary non-indigenous diseases in one food and in one non-food sector. Finally, a model is proposed for greater integration of stakeholders in policy decisions.

RESUMO

BACKGROUND: Previous studies have indicated that postprandial hypotension (PPH) and orthostatic hypotension (OH) occur infrequently together. As data on geriatric patients in hospitals are scarce, we investigated the prevalence of PPH and OH and their combined occurrence. Our study sample included patients admitted to two geriatric departments in Dutch hospitals. METHODS: During 9 months, hemodynamic changes were measured with Spacelab 90207 after standing and after meals in all eligible patients. PPH is defined as a meal-related decline in systolic blood pressure (SBP) > or =20 mmHg, OH after standing up. RESULTS: Eighty-five patients (44 men), mean age 80 +/- 7 years (range 60-98 years), with 4 +/- 2 diseases and 6 +/- 3 prescriptions, were included. PPH was present in 57 patients (67%) with a significant postmeal SBP decrease of 34 +/- 4 mmHg. OH was present in 44 patients (52%) with a mean SBP decline of 44 +/- 4 mmHg after standing. Thirty-two patients (37%) had OH and PPH. Only 16 patients (19%) had neither OH nor PPH. Symptoms of PPH were present in 65% of patients, with syncope (in five patients) and sleepiness as the most common symptoms. OH was symptomatic in 61% of patients, with dizziness and risk for falls as the most common symptoms. CONCLUSIONS: PPH and OH are more common in geriatric patients than was previously appreciated, with a high statistical probability that OH and PPH occur simultaneously. There is little overlap in symptoms of OH (dizziness, fall risk) versus PPH (sleepiness, syncope), which can play an important role in diagnosis. Because of the high prevalence of symptomatic PPH and OH, blood pressure measurements for diagnosing hypotensive syndromes should be part of a comprehensive geriatric assessment.

RESUMO

OBJECTIVE: Outcomes analysis in congenital diaphragmatic hernia (CDH) requires a validated risk-adjustment tool. The purpose of this study was to use the Canadian Neonatal Network (CNN) database to validate the Score for Neonatal Acute Physiology, Version II (SNAP-II) for prediction of mortality among CDH infants admitted to a neonatal intensive care unit (NICU), and to compare this to the predictive equation recently developed by the Congenital Diaphragmatic Hernia Study Group (CDHSG). STUDY DESIGN: Infants with CDH in the CNN database were identified. Bivariate and multivariable logistic regression models were used to identify risk factors predictive of mortality. Model predictive performance and calibration were assessed using the area under the receiver operator characteristic curve and the technique of Hosmer-Lemeshow, respectively, and compared with the CDHSG predictive equation. RESULTS: There were 88 patients with CDH among 19,507 admissions to CNN hospitals. The mortality rate among CDH patients surviving to NICU admission was 17%, and 12.5% received extracorporeal membrane oxygenation therapy. Gestational age and admission SNAP-II score predicted mortality. Model predictive performance and calibration were optimized with these variables combined. The CDHSG equation was equally predictive of mortality, but was only marginally calibrated. CONCLUSIONS: SNAP-II is highly predictive of mortality among patients with CDH, and can be used to risk-adjust these patients.

RESUMO

Knowledge about possible genotoxic effects of low-dose radiation on the human germline is limited and relies primarily on extrapolations from high-dose exposures. To test whether ionizing radiation can cause paternal genetic mutations that are transmitted to offspring, we enrolled families of 88 Chernobyl cleanup workers exposed to ionizing radiation. We analyzed DNA isolated from lymphocytes for mutations via DNA blotting with the multi-locus minisatellite probes 33.6 and 33.15 and via PCR in a panel of six tetranucleotide repeats. Children conceived before and children conceived after their father's exposure showed no statistically significant differences in mutation frequencies. We saw an increase in germline microsatellite mutations after radiation exposure that was not statistically significant. We found no dependence of mutation rate on increasing exposure. A novel finding was that the tetranucleotide marker D7S1482 demonstrated germline hypermutability. In conclusion, our results do not support an increased level of germline minisatellite mutations but suggest a modest increase in germline mutations in tetranucleotide repeats. Small sample size, however, limited statistical power.

RESUMO

Breast cancer is by far the most frequent cancer among women worldwide. Its determinants include reproductive events, exogenous and endogenous hormone levels and metabolism, exposures, such as radiation and chemicals, and genetics. This paper will review available evidence from all of these areas, exploring the occurrence of cancer, risk factors for occurrence and the hormonal milieu that underlies it.
