RESUMEN

BACKGROUND: The COVID-19 pandemic brought digital practices and engagement to the forefront of society, which were based on behavioral changes associated with adhering to different government mandates. Further behavioral changes included transitioning from working in the office to working from home, with the use of various social media and communication platforms to maintain a level of social connectedness, especially given that many people who were living in different types of communities, such as rural, urban, and city spaces, were socially isolated from friends, family members, and community groups. Although there is a growing body of research exploring how technology is being used by people, there is limited information and insight about the digital practices employed across different age cohorts living in different physical spaces and residing in different countries. OBJECTIVE: This paper presents the findings from an international multisite study exploring the impact of social media and the internet on the health and well-being of individuals in different countries during the COVID-19 pandemic. METHODS: Data were collected via a series of online surveys deployed between April 4, 2020, and September 30, 2021. The age of respondents varied from 18 years to over 60 years across the 3 regions of Europe, Asia, and North America. On exploring the associations of technology use, social connectedness, and sociodemographic factors with loneliness and well-being through bivariate and multivariate analyses, significant differences were observed. RESULTS: The levels of loneliness were higher among respondents who used social media messengers or many social media apps than among those who did not use social media messengers or used ≤1 social media app. Additionally, the levels of loneliness were higher among respondents who were not members of an online community support group than among those who were members of an online community support group. Psychological well-being was significantly lower and loneliness was significantly higher among people living in small towns and rural areas than among those living in suburban and urban communities. Younger respondents (18-29 years old), single adults, unemployed individuals, and those with lower levels of education were more likely to experience loneliness. CONCLUSIONS: From an international and interdisciplinary perspective, policymakers and stakeholders should extend and explore interventions targeting loneliness experienced by single young adults and further examine how this may vary across geographies. The study findings have implications across the fields of gerontechnology, health sciences, social sciences, media communication, computers, and information technology.

RESUMEN

Existing research surrounding dating apps has primarily focused on younger people with few studies exploring usage of such apps by middle aged and older adults. The worldwide COVID-19 pandemic challenged social behaviours and forced people to adapt intimacy and wider relationship conduct. The objective of this study was to examine how older adults utilized dating apps during the lockdowns of the UK pandemic (December 2020-May 2021). Findings presented here focus on qualitative data collected from an online survey and eight online, one-to-one interviews with adults aged 40-54 years. The online survey targeted adults across the UK while interviewees were located across England. Employing interpretative phenomenological analysis, findings identified three key themes: 1. Morality, health, and law breaking and COVID-19; 2. Self-surveillance and moral signalling; 3. Loneliness and social isolation. Qualitative findings show engaging with apps was a proxy which alleviated feelings of loneliness and social isolation. Some users used the premise of their social bubble as a way of meeting other people. Using the same premise, others justified breaking the law to engage in physical and sexual intimacy to mitigate their loneliness. The work presented here contributes to the fields of social sciences, gerontology, and human computer interaction. The inter- and multi-disciplinary impact of this study intersects across those fields and offers a cross-sectional insight into behaviours and engagement with technology during one of the most extraordinary global events.

RESUMEN

OBJECTIVE: Women have the right to make choices during pregnancy and birth that sit outside clinical guidelines, medical recommendations, or normative expectations. Declining recommended place or mode of birth, routine intervention or screening can be considered 'non-normative' within western cultural and social expectations around pregnancy and childbirth. The aim of this review is to establish what is known about the experiences, views, and perceptions of women who make non-normative choices during pregnancy and childbirth to uncover new understandings, conceptualisations, and theories within existing literature. METHODS: Using the meta-ethnographic method, and following its seven canonical stages, a systematic search of databases was performed, informed by eMERGe guidelines. FINDINGS: Thirty-three studies met the inclusion criteria. Reciprocal translation resulted in three third order constructs - 'influences and motivators', 'barriers and conflict and 'knowledge as empowerment'. Refutational translation resulted in one third order construct - 'the middle ground', which informed the line of argument synthesis and theoretical insights. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The findings of this review suggest that whilst existing literature from a range of high-income countries with similar healthcare systems to the UK have begun to explore non-normative decision-making for discrete episodes of care and choices, knowledge based, theoretical and population gaps exist in relation to understanding the experiences of, and wider social processes involved in, making non-normative choices across the UK maternity care continuum.

RESUMEN

This article explores the experiences of young adults with a life-shortening condition in the first wave of the Coronavirus (COVID-19) pandemic in the UK. It presents the findings from an inclusive qualitative research study using constructivist grounded theory which aimed to examine the unintended consequences of pandemic control measures (lockdown and 'shielding') on this population. Purposive and theoretical sampling methods were used to recruit young adults with a life-shortening condition, employing a range of recruitment methods such as social media, advertising in newsletters and snowballing. Twenty-six young adults (aged 22-40 years), with a wide range of life-shortening conditions participated in the study. Seventeen participants were female and nine male. The majority identified as White British/Other and the remainder as Black British (2), Mixed Race (2) or Latin American (1). Data were generated iteratively using in-depth guided interviews and analysed collectively by an inclusive research team using the constant comparative method. The article explores a theory of embodied precariousness of living with a life-shortening condition during the first wave of the Coronavirus pandemic in relation to three categories: the rationing of life-saving treatment, the deterioration of health and retraction of healthcare provision, and the disruption of typical care arrangements. The findings show that the pandemic control measures introduced to keep people safe have intensified the precarity of this group promoting inequalities in healthcare and health outcomes. The article identifies some implications for practice to support the future management of unexpected and unwanted change.

RESUMEN

Streptococcus pneumoniae is a major human pathogen that can cause severe invasive diseases such as pneumonia, septicaemia and meningitis. Young children are at a particularly high risk, with an estimated 3-4 million cases of severe disease and between 300 000 and 500 000 deaths attributable to pneumococcal disease each year. The haemolytic toxin pneumolysin (Ply) is a primary virulence factor for this bacterium, yet despite its key role in pathogenesis, immune evasion and transmission, the regulation of Ply production is not well defined. Using a genome-wide association approach, we identified a large number of potential affectors of Ply activity, including a gene acquired horizontally on the antibiotic resistance-conferring Integrative and Conjugative Element (ICE) ICESp23FST81. This gene encodes a novel modular protein, ZomB, which has an N-terminal UvrD-like helicase domain followed by two Cas4-like domains with potent ATP-dependent nuclease activity. We found the regulatory effect of ZomB to be specific for the ply operon, potentially mediated by its high affinity for the BOX repeats encoded therein. Using a murine model of pneumococcal colonization, we further demonstrate that a ZomB mutant strain colonizes both the upper respiratory tract and lungs at higher levels when compared to the wild-type strain. While the antibiotic resistance-conferring aspects of ICESp23FST81 are often credited with contributing to the success of the S. pneumoniae lineages that acquire it, its ability to control the expression of a major virulence factor implicated in bacterial transmission is also likely to have played an important role.

RESUMEN

AIM: To explore how women and their partners navigate (pre)conception healthcare and the role of Natural Cycles fertility awareness technology in this process. METHODS: In-depth interviews with 24 cisgender women aged 24-43 years who had used Natural Cycles' 'Plan a Pregnancy' mode, and six partners of Natural Cycles users, all cisgender men aged 30-39 years. Participants were recruited via direct messaging in the Natural Cycles app, social media and, for partners, snowball sampling. Purposive sampling was conducted to ensure diversity among participants. Interviews were audio-recorded and transcribed verbatim. An iterative, inductive approach was adopted for thematic data analysis. RESULTS: Natural Cycles helped most users better understand their menstrual cycles and fertility. Fertility awareness and preconception counselling with healthcare providers were uncommon. Women felt discussions about planning pregnancy in healthcare settings were often fraught with difficulties. They described not wanting to be an extra burden to overworked staff, being concerned that their worries about trying for pregnancy would be dismissed, or feeling staff did not have expertise in fertility awareness. Some women had shared their Natural Cycles data with healthcare professionals to demonstrate their menstrual cycle data or time of conception. However, it was not always clear to those not accessing services when they should seek further advice, for example, those using the app for longer time periods who had not yet conceived. CONCLUSIONS: Digital technologies can provide information and support for those wanting to conceive. They should, however, complement care in statutory services, and be accompanied by greater investment in fertility awareness and preconception support.

RESUMEN

Staphylococcus aureus is a major bacterial pathogen in humans, and a dominant cause of severe bloodstream infections. Globally, antimicrobial resistance (AMR) in S. aureus remains challenging. While human risk factors for infection have been defined, contradictory evidence exists for the role of bacterial genomic variation in S. aureus disease. To investigate the contribution of bacterial lineage and genomic variation to the development of bloodstream infection, we undertook a genome-wide association study comparing bacteria from 1017 individuals with bacteraemia to 984 adults with asymptomatic S. aureus nasal carriage. Within 984 carriage isolates, we also compared healthcare-associated (HA) carriage with community-associated (CA) carriage. All major global lineages were represented in both bacteraemia and carriage, with no evidence for different infection rates. However, kmers tagging trimethoprim resistance-conferring mutation F99Y in dfrB were significantly associated with bacteraemia-vs-carriage (P=10-8.9-10-9.3). Pooling variation within genes, bacteraemia-vs-carriage was associated with the presence of mecA (HMP=10-5.3) as well as the presence of SCCmec (HMP=10-4.4). Among S. aureus carriers, no lineages were associated with HA-vs-CA carriage. However, we found a novel signal of HA-vs-CA carriage in the foldase protein prsA, where kmers representing conserved sequence allele were associated with CA carriage (P=10-7.1-10-19.4), while in gyrA, a ciprofloxacin resistance-conferring mutation, L84S, was associated with HA carriage (P=10-7.2). In an extensive study of S. aureus bacteraemia and nasal carriage in the UK, we found strong evidence that all S. aureus lineages are equally capable of causing bloodstream infection, and of being carried in the healthcare environment. Genomic variation in the foldase protein prsA is a novel genomic marker of healthcare origin in S. aureus but was not associated with bacteraemia. AMR determinants were associated with both bacteraemia and healthcare-associated carriage, suggesting that AMR increases the propensity not only to survive in healthcare environments, but also to cause invasive disease.

RESUMEN

Many invasive bacterial diseases are caused by organisms that are ordinarily harmless components of the human microbiome. Effective interventions against these microbes require an understanding of the processes whereby symbiotic or commensal relationships transition into pathology. Here, we describe bacterial genome-wide association studies (GWAS) of Neisseria meningitidis, a common commensal of the human respiratory tract that is nevertheless a leading cause of meningitis and sepsis. An initial GWAS discovered bacterial genetic variants, including single nucleotide polymorphisms (SNPs), associated with invasive meningococcal disease (IMD) versus carriage in several loci across the meningococcal genome, encoding antigens and other extracellular components, confirming the polygenic nature of the invasive phenotype. In particular, there was a significant peak of association around the fHbp locus, encoding factor H binding protein (fHbp), which promotes bacterial immune evasion of human complement by recruiting complement factor H (CFH) to the meningococcal surface. The association around fHbp with IMD was confirmed by a validation GWAS, and we found that the SNPs identified in the validation affected the 5' region of fHbp mRNA, altering secondary RNA structures, thereby increasing fHbp expression and enhancing bacterial escape from complement-mediated killing. This finding is consistent with the known link between complement deficiencies and CFH variation with human susceptibility to IMD. These observations demonstrate the importance of human and bacterial genetic variation across the fHbp:CFH interface in determining IMD susceptibility, the transition from carriage to disease.

RESUMEN

OBJECTIVE: The research project addressed the need to support young adults with issues relating to sexuality and relationships though the development of guidance and standards for practice. METHODS: An action research project underpinned by an interpretivist qualitative framework. Participants were recruited to the project via three hospices in the UK. Data from four focus groups were analysed thematically using a process of constant comparison. RESULTS: Sixteen young adults with life-limiting or life-threatening conditions aged 21-33 years participated in the study. Three significant themes were identified: sexuality and the transition to adulthood, recognising the significance of sex and relationships, and realising sexual rights. CONCLUSION: Sexuality and relationships play an important role in the transition to adulthood for people with life-limiting or life-threatening conditions living in the UK. While young adults with these conditions may have considerable support needs, it is important to balance this with the freedom to exercise choice and to make independent decisions. Sex negativity can have an adverse impact on the experiences of young adults and creates barriers. Improved ongoing access to sex education and the provision of enabling environments that afford privacy and safety are important to support young adults with sexuality and relationships.

RESUMEN

INTRODUCTION: There has been a phenomenal worldwide increase in the development and use of mobile health applications (mHealth apps) that monitor menstruation and fertility. Critics argue that many of the apps are inaccurate and lack evidence from either clinical trials or user experience. The aim of this scoping review is to provide an overview of the research literature on mHealth apps that track menstruation and fertility. METHODS: This project followed the PRISMA Extension for Scoping Reviews. The ACM, CINAHL, Google Scholar, PubMed and Scopus databases were searched for material published between 1 January 2010 and 30 April 2019. Data summary and synthesis were used to chart and analyse the data. RESULTS: In total 654 records were reviewed. Subsequently, 135 duplicate records and 501 records that did not meet the inclusion criteria were removed. Eighteen records from 13 countries form the basis of this review. The papers reviewed cover a variety of disciplinary and methodological frameworks. Three main themes were identified: fertility and reproductive health tracking, pregnancy planning, and pregnancy prevention. CONCLUSIONS: Motivations for fertility app use are varied, overlap and change over time, although women want apps that are accurate and evidence-based regardless of whether they are tracking their fertility, planning a pregnancy or using the app as a form of contraception. There is a lack of critical debate and engagement in the development, evaluation, usage and regulation of fertility and menstruation apps. The paucity of evidence-based research and absence of fertility, health professionals and users in studies is raised.

RESUMEN

Social connectedness, sex, and intimacy are all factors associated with positive aging, facing individuals in society across the life course. Phenomenal technological developments in the 21st century have led to the increased use of smartphones, mobile apps, and dating apps for a myriad of services, and engagements. This paper focuses on two specific cohorts' who have the opportunity to engage with dating apps, older adults and young citizens with life-limiting or life-threatening conditions, and highlights issues related to the intersection of technology, societal constructions of age, disability, and online dating.

RESUMEN

BACKGROUND: Research suggests there is insufficient good quality information regarding the effectiveness of health education aimed at adults with intellectual disabilities. By analysing the literature, this review aimed to identify what constituted effectiveness in this context. METHOD: Relevant evaluations were extracted from bibliographic databases according to pre-specified criteria. Papers were analysed using QSR NVivo 11 by developing a narrative synthesis and analytic framework that identified and explored text addressing the research question. RESULTS: Twenty-two studies were included. The review identified two broad components of effective health education: mechanisms and context. Mechanisms included embedded programme flexibility, appropriate and accessible resources, and motivational delivery. An effective context included an accessible and supportive environment and longer term opportunities for reinforcement of learning. CONCLUSIONS: Important gaps in the literature highlighted a need for further research addressing community learning experiences of adults with intellectual disabilities as well as the effectiveness of infection prevention programmes.

RESUMEN

Drawn from the stress process model, the pandemic has imposed substantial stress to individual economic and mental well-being and has brought unprecedented disruptions to social life. In light of social distancing measures, and in particular physical distancing because of lockdown policies, the use of digital technologies has been regarded as the alternative to maintain economic and social activities. This paper aims to describe the design and implementation of an online survey created as an urgent, international response to the COVID-19 pandemic. The online survey described here responds to the need of understanding the effects of the pandemic on social interactions/relations and to provide findings on the extent to which digital technology is being utilized by citizens across different communities and countries around the world. It also aims to analyze the association of use of digital technologies with psychological well-being and levels of loneliness. The data will be based on the ongoing survey (comprised of several existing and validated instruments on digital use, psychological well-being and loneliness), open for 3 months after roll out (ends September) across 11 countries (Austria, France, Germany, India, Malta, Portugal, Romania, Spain, Turkey, and UK). Participants include residents aged 18 years and older in the countries and snowball sampling is employed via social media platforms. We anticipate that the findings of the survey will provide useful and much needed information on the prevalence of use and intensities of digital technologies among different age groups, gender, socioeconomic groups in a comparative perspective. Moreover, we expect that the future analysis of the data collected will show that different types of digital technologies and intensities of use are associated with psychological well-being and loneliness. To conclude, these findings from the study are expected to bring in our understanding the role of digital technologies in affecting individual social and emotional connections during a crisis.

RESUMEN

Pyomyositis is a severe bacterial infection of skeletal muscle, commonly affecting children in tropical regions, predominantly caused by Staphylococcus aureus. To understand the contribution of bacterial genomic factors to pyomyositis, we conducted a genome-wide association study of S. aureus cultured from 101 children with pyomyositis and 417 children with asymptomatic nasal carriage attending the Angkor Hospital for Children, Cambodia. We found a strong relationship between bacterial genetic variation and pyomyositis, with estimated heritability 63.8% (95% CI 49.2-78.4%). The presence of the Panton-Valentine leucocidin (PVL) locus increased the odds of pyomyositis 130-fold (p=10-17.9). The signal of association mapped both to the PVL-coding sequence and to the sequence immediately upstream. Together these regions explained over 99.9% of heritability (95% CI 93.5-100%). Our results establish staphylococcal pyomyositis, like tetanus and diphtheria, as critically dependent on a single toxin and demonstrate the potential for association studies to identify specific bacterial genes promoting severe human disease.

RESUMEN

Spinal cord injuries can result in significant physiological and psychological challenges for patients. Nurses have an important role in the rehabilitation of people with a spinal cord injury, as does the provision of peer support by people who are 'living well' after experiencing a spinal cord injury. AIM: To explore peer support and whether it can have an effective role in a multidisciplinary team approach to supporting a patient with a spinal cord injury. METHOD: This was an independent evaluation that used an online survey, a focus group and telephone interviews to elicit the views of respondents about the Spinal Injury Association (SIA) peer support service in England and Wales. There were four groups of respondents: people with a spinal cord injury; their family and friends; peer support officers; and nurse specialists and other healthcare practitioners. FINDINGS: It was identified that peer support officers were valued for their ability to provide a positive role model for people with a spinal cord injury. Healthcare practitioners involved in the care of people with a spinal cord injury also appreciated the training and support they received from peer support officers. CONCLUSION: This evaluation demonstrated that peer support officers were regarded as an important element of a multidisciplinary team approach to managing the care of those who had experienced a spinal cord injury. Peer support officers were also considered a valuable source of information and education, particularly for healthcare practitioners working in settings where spinal cord injury was not a common presentation.

RESUMEN

Although the advantages of breastfeeding are well documented, rates for breastfeeding often fall short of international and national targets. Increasing attention has been paid to the role of men in infant feeding, but a lot of the research about men has been elicited from women, rather than from men themselves. To explore these issues further, a systematic review of the qualitative research on infant feeding was carried out, focusing specifically on men's own views and experiences. Evidence was identified by searching electronic databases (CINAL, Cochrane, PubMed, and Scopus), manually searching citations, and by searching the grey literature. Studies were included in the review if they discussed men's views and experiences of infant feeding and if they reported primary qualitative data. Twenty research papers were included in the review, and each study was summarised and then analysed thematically to produce a synthesis. Five major analytical themes were identified: men's knowledge of infant feeding; men's perceptions of their role in infant feeding; positive views on breastfeeding; negative views on breastfeeding; and men's experiences of health promotion and support. The review concludes by highlighting that although men can play an important role in supporting women, they do not have a significant role in infant feeding decisions.

RESUMEN

BACKGROUND: Diabetes mellitus is a global health problem and one of the most common medical conditions in pregnancy. A wide range of modifiable risk factors are associated with diabetes mellitus in pregnancy, and it is widely acknowledged that preconception care (PCC) is beneficial for women with pre-existing diabetes mellitus. However, uptake of PCC services is low. OBJECTIVES: To systematically review qualitative research on PCC for women with pre-existing diabetes mellitus of childbearing age, identify facilitators of and barriers to uptake of PCC and establish themes and gaps in knowledge. Through qualitative interviews explore views on the provision of, and facilitators of and barriers to the uptake of, PCC. DESIGN: Mixed methods encompassing a systematic review and qualitative interviews. SETTING: Two secondary care sites and 11 primary care sites. PARTICIPANTS: Women of childbearing age with pre-existing type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) of white British or Pakistani origin. INTERVENTIONS: None. ANALYSIS: A narrative synthesis of the literature using thematic analysis and a thematic analysis of the qualitative interview data using the method of constant comparison. RESULTS: Eighteen qualitative studies were included in the systematic review and a quality appraisal was carried out using relevant criteria for qualitative research appraisal, including a narrative summary of study quality. Twelve interviews with women with pre-existing T1DM or T2DM were carried out. This fell short of the original aim of interviewing 48 women owing to challenges in recruitment, especially in primary care. A synthesis of these data shows that uptake of PCC is influenced by a range of factors, including the complexity of pregnancy planning, the skill and expertise of health professionals who provide care to women with diabetes mellitus, the role of health professionals in the delivery of PCC, and the quality of relationships between women and health professionals. LIMITATIONS: Owing to significant challenges with recruitment of participants, particularly in primary care, 12 interviews with women with pre-existing T1DM or T2DM were carried out, which fell short of the a priori sample size. CONCLUSIONS: Reconceptualising PCC to place greater emphasis on pregnancy planning, fertility and contraception would lower some of the existing barriers to uptake of care. It is important to clarify who is responsible for the delivery of PCC to women with pre-existing diabetes mellitus and to ensure that the correct expertise is available so that opportunities for advice giving are maximised. Relationships between women and health professionals should be based on a partnership approach that encourages mutual trust and respect, focusing on positive change rather than negative outcomes. FUTURE WORK: Further research is needed to investigate the views and experiences of stakeholders that commission, design and deliver PCC services for women with pre-existing diabetes mellitus; to explore experiences of women from minority or ethnically diverse backgrounds; to investigate the role of family support in contraception, pregnancy planning and PCC; and to investigate the management of diabetes mellitus in neonatal care and its role in breastfeeding. STUDY REGISTRATION: This study is registered as PROSPERO CRD42014015592 and ISRCTN12983949. FUNDING: The National Institute for Health Research Health Technology Assessment programme.

RESUMEN

Bacteria pose unique challenges for genome-wide association studies because of strong structuring into distinct strains and substantial linkage disequilibrium across the genome(1,2). Although methods developed for human studies can correct for strain structure(3,4), this risks considerable loss-of-power because genetic differences between strains often contribute substantial phenotypic variability(5). Here, we propose a new method that captures lineage-level associations even when locus-specific associations cannot be fine-mapped. We demonstrate its ability to detect genes and genetic variants underlying resistance to 17 antimicrobials in 3,144 isolates from four taxonomically diverse clonal and recombining bacteria: Mycobacterium tuberculosis, Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae. Strong selection, recombination and penetrance confer high power to recover known antimicrobial resistance mechanisms and reveal a candidate association between the outer membrane porin nmpC and cefazolin resistance in E. coli. Hence, our method pinpoints locus-specific effects where possible and boosts power by detecting lineage-level differences when fine-mapping is intractable.
