Risk Perceptions of Environmental Hazards and Human Reproduction: A Community Based Survey

Objectives: We have investigated the Australian public’s perceived risks on human reproductive health from a number of identified environmental hazards. Methods: A sample of 1261 subjects were interviewed. This interview included specific questions related to perceived risks of certain environmental hazards to human reproductive health. Results: Women were almost twice as likely to rank all hazards as harmful or very harmful to human reproduction than men. Age also influenced perceived risk with those in the 35 and older age groups more likely to rank lead as a harmful hazard when compared with the 18-34 group. Pesticides were identified by 84.5% of the sample as the most harmful environmental hazard to human reproduction. Conclusions: Similar to other environmental hazards, different groups of people in the general population perceive hazards relating to reproductive health differently. This information is important for both policy makers and health professionals dealing with reproductive environmental health issues

A physical activity intervention in a Bingo club: Significance of the setting

Objective:  A Bingo club was selected for the design and delivery of a health intervention (Well!Bingo) in order to engage with older women living in areas areas of socio-economic disadvantage. In the light of our experience, we discuss the significance of the setting in relation to a typology of health promotion settings.  Design and Setting:  The Well!Bingo physical activity intervention was piloted in a Bingo club in Scotland.  Methods:  In a pilot feasibility study, women were recruited face-to-face at a Bingo club over two weeks. The 12-week intervention consisted of three different structured exercise sessions per week, followed by refreshments, with trained instructors delivering a schedule of simple pre-defined health messages. Participants completed a baseline questionnaire, and in-depth qualitative interviews were carried out with participants and instructors post-intervention. For this paper, using the framework method, we retrieved and analysed the data coded as relating to the setting.  Results:  Eighteen women (55-92 years) took part in intervention sessions. Half lived in areas of socio-economic deprivation. Practical and social familiarity with the setting (a sense of belonging and being with people like themselves) encouraged them to take part, and implicit features of the setting may have enhanced recruitment and effectiveness.  Discussion:  In settings-based health promotion, a Bingo club could be seen as a ‘passive' setting, simply facilitating access to a target population. It cannot be an ‘active setting', because health promotion will never be a core activity and features cannot be drawn upon to influence change. However, calling it a passive setting overlooks the importance of characteristics that may enhance recruitment and effectiveness. This highlights the need to extend current concepts of ‘passive' health promotion settings

Measuring the impact of genetic heterogeneity and chromosomal inversions on the efficacy of CRISPR-Cas9 gene drives in different strains of Anopheles gambiae

The human malaria vector Anopheles gambiae is becoming increasingly resistant to insecticides, spurring the development of genetic control strategies. CRISPR-Cas9 gene drives can modify a population by creating double-stranded breaks at highly specific targets, triggering copying of the gene drive into the cut site (‘homing’), ensuring its inheritance. The DNA repair mechanism responsible requires homology between the donor and recipient chromosomes, presenting challenges for the invasion of lab-developed gene drives into wild populations of target species An. gambiae species complex, which show high levels of genome variation. Two gene drives (vas2-5958 and zpg-7280) were introduced into three An. gambiae strains collected across Africa with 5.3-6.6% variation around the target sites, and the effect of this variation on homing was measured. Gene drive homing across different karyotypes of the 2La chromosomal inversion was also assessed. No decrease in gene drive homing was seen despite target site heterology, demonstrating the applicability of gene drives to wild populations

How active are women who play bingo: a cross-sectional study from the Well!Bingo project

BackgroundThe benefits of physical activity are well established, yet large numbers of people are not sufficiently active to gain health benefits. Certain population groups are less physically active than others, including older women from areas of high economic deprivation. The Well!Bingo project was established with the aim of engaging such women in the development of a health promotion intervention in a bingo club. This paper reports on the assessment of health status, physical activity and sedentary behaviour of women attending a bingo club in central Scotland, UK as part of the Well!Bingo project.MethodsWomen attending the bingo club were invited to provide information on demographic characteristics, and self-reported physical activity and sedentary behaviour via a self-complete questionnaire as part of a cross-sectional study (n = 151). A sub-sample (n = 29) wore an accelerometer for an average of 5.7 ± 1.4 days. Differences between younger (under 60 years) and older adults (60 years and over) were assessed using a chi-square test for categorical data and the independent samples t-test was used to assess continuous data (p < 0.05).ResultsThe mean age was 56.5 ± 17.7 years, with 57% living in areas of high deprivation (Scottish Index of Multiple Deprivation quintile one and two). Sixty-three percent of women (n = 87) reported they were meeting physical activity guidelines. However, objective accelerometer data showed that, on average, only 18.1 ± 17.3 min a day were spent in moderate to vigorous physical activity. Most accelerometer wear time was spent sedentary (9.6 ± 1.7 h). For both self-report and accelerometer data, older women were significantly less active and more sedentary than younger women. On average, older women spent 1.8 h more than younger women in sedentary activities per day, and took part in 21 min less moderate to vigorous physical activity (9.4 mins per day).ConclusionThe findings of this study suggest that bingo clubs are settings that attract women from areas of high deprivation and older women in bingo clubs in particular would benefit from interventions to target their physical activity and sedentary behaviour. Bingo clubs may therefore be potential intervention settings in which to influence these behaviours

Accessing and engaging women from socio-economically disadvantaged areas: a participatory approach to the design of a public health intervention for delivery in a Bingo club

Background Our aim was to use participatory methods to investigate the feasibility and acceptability of using Bingo clubs for the design and delivery of an evidence-based physical activity and/or healthy eating intervention to socio-economically disadvantaged women. This paper describes the participatory process that has resulted in a physical activity intervention for women aged >55years, ready for pilot-testing in a Bingo club setting. Methods Studies using different quantitative and qualitative approaches were conducted among customers and staff of a Bingo club in a city of 85,000 inhabitants in central Scotland. These were designed to take the views of different stakeholders into account, with a view to enhancing uptake, engagement and effectiveness with any proposed intervention. Results Sixteen relevant studies were identified in a literature review that generated ideas for intervention components. A questionnaire completed by 151 women in the Bingo club showed that almost half (47%) aged >55years were not meeting physical activity guidelines; evidence backed up by accelerometer data from 29 women. Discussions in six focus groups attended by 27 club members revealed different but overlapping motivations for attending the Bingo club (social benefits) and playing Bingo (cognitive benefits). There was some scepticism as to whether the Bingo club was an appropriate setting for an intervention, and a dietary intervention was not favoured. It was clear that any planned intervention needed to utilise the social motivation and habitual nature of attendance at the Bingo club, without taking women away from Bingo games. These results were taken forward to a 5-h long participative workshop with 27 stakeholders (including 19 Bingo players). Intervention design (form and content) was then finalised during two round table research team meetings. Conclusions It was possible to access and engage with women living in areas of socio-economic disadvantage through a Bingo club setting. A physical activity intervention for women >55years is realistic for recruitment, will address the needs of potential recipients in the Bingo club, appears to be feasible and acceptable to club members and staff, and has been designed with their input. A pilot study is underway, investigating recruitment, retention and feasibility of delivery

Integrating qualitative research within a clinical trials unit: developing strategies and understanding their implementation in contexts

Background/aims: The value of using qualitative methods within clinical trials is widely recognised. How qualitative research is integrated within trials units to achieve this is less clear. This paper describes the process through which qualitative research has been integrated within Cardiff University’s Centre for Trials Research (CTR) in Wales, UK. We highlight facilitators of, and challenges to, integration. Methods: We held group discussions on the work of the Qualitative Research Group (QRG) within CTR. The content of these discussions, materials for a presentation in CTR, and documents relating to the development of the QRG were interpreted at a workshop attended by group members. Normalisation Process Theory (NPT) was used to structure analysis. A writing group prepared a document for input from members of CTR, forming the basis of this paper. Results: Actions to integrate qualitative research comprised: its inclusion in Centre strategies; formation of a QRG with dedicated funding/roles; embedding of qualitative research within operating systems; capacity building/training; monitoring opportunities to include qualitative methods in studies; maximising the quality of qualitative research and developing methodological innovation. Facilitators of these actions included: the influence of the broader methodological landscape within trial/study design and its promotion of the value of qualitative research; and close physical proximity of CTR qualitative staff/students allowing sharing of methodological approaches. Introduction of innovative qualitative methods generated interest among other staff groups. Challenges included: pressure to under-resource qualitative components of research, preference for a statistical stance historically in some research areas and funding structures, and difficulties faced by qualitative researchers carving out individual academic profiles when working across trials/studies. Conclusions: Given that CTUs are pivotal to the design and conduct of RCTs and related study types across multiple disciplines, integrating qualitative research into trials units is crucial if its contribution is to be fully realised. We have made explicit one trials unit’s experience of embedding qualitative research and present this to open dialogue on ways to operationalise and optimise qualitative research in trials. NPT provides a valuable framework with which to theorise these processes, including the importance of sense-making and legitimisation when introducing new practices within organisations

Chronic Obstructive Pulmonary Disease and Lung Cancer: Underlying Pathophysiology and New Therapeutic Modalities

Chronic obstructive pulmonary disease (COPD) and lung cancer are major lung diseases affecting millions worldwide. Both diseases have links to cigarette smoking and exert a considerable societal burden. People suffering from COPD are at higher risk of developing lung cancer than those without, and are more susceptible to poor outcomes after diagnosis and treatment. Lung cancer and COPD are closely associated, possibly sharing common traits such as an underlying genetic predisposition, epithelial and endothelial cell plasticity, dysfunctional inflammatory mechanisms including the deposition of excessive extracellular matrix, angiogenesis, susceptibility to DNA damage and cellular mutagenesis. In fact, COPD could be the driving factor for lung cancer, providing a conducive environment that propagates its evolution. In the early stages of smoking, body defences provide a combative immune/oxidative response and DNA repair mechanisms are likely to subdue these changes to a certain extent; however, in patients with COPD with lung cancer the consequences could be devastating, potentially contributing to slower postoperative recovery after lung resection and increased resistance to radiotherapy and chemotherapy. Vital to the development of new-targeted therapies is an in-depth understanding of various molecular mechanisms that are associated with both pathologies. In this comprehensive review, we provide a detailed overview of possible underlying factors that link COPD and lung cancer, and current therapeutic advances from both human and preclinical animal models that can effectively mitigate this unholy relationship

Factors associated with health-related quality of life among patients with liver cirrhosis in Egypt

Background: Although the disease burden of liver cirrhosis in Egypt is high and there are few resources for its management, there is limited research on the health-related quality of life (HRQOL) of Egyptian patients with liver cirrhosis. Aims: To describe the HRQOL of liver cirrhotic patients in Egypt and to analyse factors associated with this construct. Patients and methods: A cross-sectional study with a convenience sample of 401 patients from three hospitals in Cairo, Egypt, was carried out in June-August 2011. Patients were interviewed to complete a background data form, Short Form-36, the Liver Disease Symptom Index-2.0 and the Multidimensional Scale of Perceived Social Support. Results: Patients had low HRQOL, with mental health perceived to be poorer than physical health. In regression analyses, severity of symptoms, disease stage, comorbidities and employment status were associated significantly with physical health, accounting for 19% of the variance. For mental health, 31.7% of the variation was explained by severity of symptoms, employment status and perceived spouse and family support. Conclusion and recommendations: These findings highlight the needs of patients with liver cirrhosis in Egypt. Engaging the patients' family in care planning may decrease patients' burden and improve their HRQOL. This study also provides a rationale to develop future research in symptom management to enhance HRQOL

Homing gene drives can transfer rapidly between Anopheles gambiae strains with minimal carryover of flanking sequences

CRISPR-Cas9 homing gene drives are designed to induce a targeted double-stranded DNA break at a wild type allele (‘recipient’), which, when repaired by the host cell, is converted to the drive allele from the homologous (‘donor’) chromosome. Germline localisation of this process leads to super-Mendelian inheritance of the drive and the rapid spread of linked traits, offering a novel strategy for population control through the deliberate release of drive individuals. During the homology-based DNA repair, additional segments of the recipient chromosome may convert to match the donor, potentially impacting carrier fitness and strategy success. Using Anopheles gambiae strains with variations around the drive target site, here we assess the extent and nature of chromosomal conversion. We show both homing and meiotic drive contribute as mechanisms of inheritance bias. Additionally, over 80% of homing events resolve within 50 bp of the chromosomal break, enabling rapid gene drive transfer into locally-adapted genetic backgrounds

COVID and Isolation: The Effects of a Global Pandemic on the Carroll Community

A study done on graduate and undergraduate students in September of 2020 discovered that 71.26% suffered from increased stress and anxiety during the COVID-19 pandemic (Wang et al.). They also found that less than half of the participants in the study felt able to cope effectively with chronic or newfound stress. Wanting to see how Carroll compared to this percentage, student researchers conducted interviews, focus groups, environmental scans, and outlet density scans in order to gather results. Student researchers found that Carroll students face similar levels of increased stress due to COVID and isolation conditions. Carroll students reported worsening mental health conditions, particularly when in isolation. Interview and focus group participants described being isolated in empty apartments that didn’t include basic necessities needed for student life. There were reports of failed meal delivery, as well as students being forgotten and left in hotels. The information gathered from this project will be used to educate students on mental health services to help them address COVID related stressors. This information will also be used to inform Carroll on the needs of their students to ensure that students get what they need while in isolation
