Contextualising missed opportunities for children's vaccination: A theory-informed qualitative study in primary care settings in Cape Town, South Africa

This study aimed to explore the contextual factors that may be associated with missed opportunities for vaccination (MOV) from the perspectives of healthcare providers and caregivers attending primary healthcare facilities in the Cape Town Metro Health District, South Africa. The ultimate goal of the assessment was to help inform the design and implementation of a contextually appropriate quality improvement programme targeted at reducing MOV in primary healthcare settings. We used a theory-informed exploratory qualitative research design involving focus group discussions with caregivers of children aged 0-23 months; and in-depth interviews of facility staff. A thematic template analysis approach, integrating the theoretical domains framework (TDF) and the capability, opportunity and motivation model of behavior (COM-B) was used to code and analyze the data. Three focus group sessions were conducted, each consisting of 5-8 caregivers and five in-depth interviews involving facility staff. Capability factors comprised caregivers' knowledge, attitude and behavior toward children's immunization. Opportunity factors included the organization of immunization services, long waiting time, vaccine stock out, staff shortage and health workers' attitude, knowledge and capability to assess children's immunization status and needs. Motivation factors included optimism and beliefs about immunization, fear of vaccine-preventable diseases and immunization safety concerns. This study identified important caregiver-, provider- and health system-related factors, which influence immunization outcomes; offering useful contextual insights for informing quality improvement strategies for reducing MOV at primary healthcare level.

Are parents' willing to vaccinate their children against COVID-19? A qualitative study based on the Health Belief Model

In response to the COVID-19 pandemic, several countries have started implementing voluntary or involuntary mass vaccination programs. Although vaccine acceptance is high among adults, uncertainty about whether to vaccinate children against COVID-19 remains a controversial theme. To date, few qualitative studies have explored parents' views on this topic. A qualitative descriptive study design was used to collect data and individual in-depth interviews were conducted with 50 parents in the Makkah region of Saudi Arabia. The Health Belief Model (HBM) was used as a guide in developing the interview guide. Each question was related to a construct of the HBM. The data were then analyzed using thematic content analysis and interpreted using NVivo software. Two major themes emerged: motivation to vaccinate children, which was influenced by perceived benefits, perceived severity, perceived suitability, collective responsibilities, confidence, and cues to action; and barriers to vaccination in children, which included complacency, rapid vaccine development, and uncertainty about the long-term side effects of the vaccine. The findings of this study revealed that the public is not sufficiently informed about the efficacy or side effects of the COVID-19 vaccine, increasing the awareness of which will help parents make informed decisions regarding vaccinating their children and potentially increase vaccine acceptance.

Beyond supply and demand: a new ecological framework for understanding the access of young migrants to sexual and reproductive health services in Sweden

BACKGROUND

Although the sexual and reproductive health and rights (SRHR) of young people and migrants should be prioritised, young migrants' sexual and reproductive health (SRH) is rarely studied in Sweden.

OBJECTIVES

To explore young migrants' understanding and experiences of sexual rights and examine their perceptions and experiences in accessing SRH services.

METHODS

This is a mixed method study including a national survey that recruited 1773 newly arrived young migrants; a youth clinic survey that recruited 1089 youths after visiting youth clinics; and a qualitative study that included 13 interviews with newly arrived Arabic-speaking migrant men. The results are synthesised using a new ecological framework of access to understand the factors influencing young migrant access to health care based on the levels of the ecological model and the five steps of access: approachability, acceptability, adequacy, affordability, and quality.

RESULTS

Young migrants understood SRH as both 'essential' and 'a right.' Their sexual rights were less fulfiled compared to other young people in Sweden, particularly for men, non-binary, LGBTQ+, those born in South Asia, without a residence permit, and those of low economic conditions. SRH services were largely unapproachable as almost half of those who needed them did not utilise them. Services were generally acceptable due to the 'open environment,' however, some young migrants faced cultural insensitivity, fear of exposure, low parental support, and long waiting times. SRH services' quality was perceived as good, however, negative experiences were reported, particularly in the domains of respect, equity, privacy, non-prejudice, and consultation quality.

CONCLUSION

The access of young migrants to SRH services is facilitated by an 'open environment' and available and good quality services; however, they faced serious barriers such as limited access to information about the health system, comprehensive sexual education, lack of cultural sensitivity, and cultural racism.

Drivers of cardiovascular disease risk factors in slums in Kampala, Uganda: a qualitative study

BACKGROUND

Cardiovascular disease (CVD) risk factors are increasing in many sub-Saharan African countries and disproportionately affecting communities in urban slums. Despite this, the contextual factors that influence CVD risk among slum communities have not been fully documented to guide interventions to prevent and control the disease.

OBJECTIVE

This study explored the drivers of CVD risk factors in slums in Kampala, Uganda.

METHODS

This qualitative study employed focus group discussions (FGDs) to collect data among slum residents. A total of 10 FGDs separate for gender and age group were held in community public places. Discussions were audio-recorded, transcribed, and transcripts analysed thematically with the aid of Atlas ti 7.0. Study themes and sub-themes are presented supported by participant quotations.

RESULTS

Five themes highlighted the drivers of CVD risk factors in slum communities. (1) Poverty: a critical underlying factor which impacted access and choice of food, work, and housing. (2) Poverty-induced stress: a key intermediate factor that led to precarious living with smoking and alcohol use as coping measures. (3) The social environment which included socialisation through drinking and smoking, and family and peers modelling behaviours. (4) The physical environment such as the high availability of affordable alcohol and access to amenities for physical activity and healthy foods. (5) Knowledge and information about CVD risk factors which included understanding of a healthy diet and the dangers of smoking and alcohol consumption.

CONCLUSION

To address CVD risk in slums, broad-ranging multisectoral interventions are required, including economic empowerment of the slum population, stress reduction and coping interventions, and alcohol legislation. Also, there is a need for community CVD sensitisation and screening as well as increasing access to physical activity amenities and healthy foods within slums.

Perioperative shared decision making - How do we train clinicians?

Objective

Decision making about high-risk surgery can be complex, particularly when outcomes may be uncertain. Clinicians have a legal and ethical responsibility to support decision making which fits with patients' values and preferences. In the UK, preoperative assessment and optimisation is led by Anaesthetists in clinic several weeks prior to planned surgery. Training in supporting shared decision making (SDM) has been identified as an area of need among UK anaesthetists with leadership roles in perioperative care.

Methods

We describe adaptation of a generic SDM workshop to perioperative care, in particular to decisions on high-risk surgery, and its delivery to UK healthcare professionals over a two-year period. Feedback from workshops were thematically analysed. We explored further improvements to the workshop and ideas for development and dissemination.

Results

The workshops were well received, with high satisfaction for techniques used, including video demonstrations, role-play and discussions. Thematic analysis identified a desire for multidisciplinary training and training in using patient aids.

Conclusion

Qualitative findings suggest workshops were considered useful with perceived improvement in SDM awareness, skills and reflective practice.

Innovation

This pilot introduces a new modality of training in the perioperative setting providing physicians, particularly Anaesthetists, with previously unavailable training needed to facilitate complex discussions.

The impact of funding disruptions on large-scale teen pregnancy prevention research projects

To advance the field of teen pregnancy prevention, new interventions must be developed and tested. The federal Teen Pregnancy Prevention program (TPP) funds the evaluation of promising interventions. We report on a funding disruption to 21 TPP Tier 2B research grantees across the US that was unusual for its ideological causation, sudden timing, severity, and ultimately court decisions compelling the agency to reverse the decision. We address the following question: How did challenges presented by the attempted funding termination impact grantees' ability to continue with their intended research? Results from grantee surveys in 2019 demonstrate the funding disruption negatively impacted participant recruitment, organizational collaboration, program delivery, research rigor, and compromised grantees' ability to complete high-quality evaluations. Results also show most projects could continue, with modified research goals, when funding was reinstated. We conclude administrations should avoid arbitrarily and prematurely terminating research projects. However, there is merit in reinstating funds to projects should a disruption occur. Results from this work are particularly relevant as we anticipate how health research projects may manage other disruptions to funding or timetables, such as those caused by COVID-19. Results are relevant to policy makers, researchers, government and private funders, grantees, and technical assistance teams.

Exploring facilitators and barriers to patient-provider communication regarding diabetes self-management

Objective

Long-term type 2 diabetes management requires open communication between a patient and their provider for self-care adherence. This study explored facilitators and barriers to diabetes-specific communication in West Virginia, a medically underserved state with the highest prevalence of diabetes (16.2%) in the U.S.

Methods

A secondary qualitative analysis was conducted using data from semi-structured interviews (n = 34) and 4 focus groups (n = 23) with participants of a diabetes education program. Transcripts were analyzed using thematic analysis.

Results

Three facilitators to patient-provider communication emerged: "Patient-Provider Partnership", "Provider Accessibility", and "Empowerment Through Education". Partnership with providers, especially those who were accessible outside of scheduled appointments, and empowerment obtained through diabetes education facilitated diabetes-specific patient-provider communication. However, barriers included "Providers' Focus on 'Numbers' Rather than Patient Concerns", "Patient Lack of Preparation for Appointments", and "Providers 'Talking Down to' Patients".

Conclusion

The findings highlight patient- and provider-related factors that impact diabetes-specific communication.

Innovation

Previous interventions have trained providers in communication skills. Despite some success, challenges in implementation remain considering providers' limited time and overwhelming demands. This study suggests that diabetes education programs incorporating communication and self-advocacy skills could be a promising alternative as they can empower patients to communicate their diabetes-specific needs/preferences with providers.

Wellness Warriors: a qualitative exploration of healthcare staff learning to support their colleagues in the aftermath of the Australian bushfires

PURPOSE

Healthcare staff are on the frontline during disasters despite any personal adversity and vicarious trauma they may be experiencing. Wellness Warrior training is a post-disaster intervention developed in response to the 2019-2020 Australian bushfires to support staff in a rural hospital located on the South Coast of New South Wales, Australia.

METHOD

This study explored the experiences and perspectives of 18 healthcare staff who were trained to provide emotional and peer support to their colleagues in the aftermath of a crisis. All the Wellness Warriors participated in semi-structured interviews between March and April 2020. Data were analysed using the reflexive thematic approach.

RESULTS

Healthcare staff reported developing interpersonal skills around deep listening and connecting with others which allowed for hearing the core of their colleagues' concerns. The training also helped staff to feel differently about work and restored their faith in healthcare leadership.

CONCLUSION

Wellness Warrior training provided staff with knowledge and skills to support their colleagues in the aftermath of a natural disaster and later during the COVID-19 pandemic. As such, these findings suggest that peer support programs such as Wellness Warriors could be one way healthcare organisations can attempt to alleviate the psychological impact of natural disasters.

A narrative medicine intervention in pediatric residents led to sustained improvements in resident well-being

BACKGROUND

Burnout in pediatric residents is widespread. Certain factors are associated with decreased burnout, such as empathy, self-compassion, mindfulness, and resilience, while perceived stress is associated with increased burnout. Narrative medicine may reduce burnout by its impact on protective and exacerbating factors and can be an active tool to promote wellness. The objective of this pilot study was to evaluate immediate and delayed benefits of a longitudinal narrative medicine intervention for pediatric residents using qualitative and quantitative measures.

MATERIALS AND METHODS

We designed a voluntary longitudinal narrative medicine intervention implemented via Zoom teleconferencing software over five months for pediatric residents at Nationwide Children's Hospital. It consisted of six one-hour long sessions where residents engaged with literature, responded to a writing prompt, and shared their reflections. It was evaluated using open-ended survey questions and established quantitative assessment tools of well-being with validity evidence. Results were compared before the intervention, immediately after, and six months later using one-way ANOVA and multiple linear regression. Qualitative data was analyzed using thematic analysis.

RESULTS

Twenty-two (14% of eligible) residents participated in at least one session. After the intervention, the following themes emerged for benefits to resident well-being: the ability to Build Community, have an Outlet for Self-Expression, reap Emotional and Mental Health Benefits, and work on Personal Growth. Benefits were sustained even six months later, which has not been shown previously. While there were significant qualitative findings, between all three time points, there was no change in any quantitative well-being measures.

CONCLUSION

Our longitudinal narrative medicine pilot study showed meaningful sustained qualitative benefits, though no quantitative changes, in measured well-being outcomes that have been previously associated with lower resident burnout. While not a panacea, narrative medicine can be a useful strategy for residency programs to improve pediatric resident well-being even after completion of planned interventions.Key MessageWe used a mixed-methods approach to assess the effects of a longitudinal narrative medicine intervention on well-being in pediatric residents.Open-ended responses indicated that residents found utility in and appreciated the intervention and experienced sustained improvements in their mental and emotional health, though the sample size was likely too small to show quantitative changes in well-being measures.Narrative medicine is not a panacea, but it can be a useful tool to provide to pediatric residents to promote sustained improvements in their well-being through the framework of relationship-centered care.

Spanish residents' experiences of care during the first wave of the COVID-19 syndemic: a photo-elicitation study

PURPOSE

The main aim of this research was to explore experiences of care during the lockdown of the first wave of COVID-19 syndemic in Spain.

METHODS

This is a qualitative and explorative study using self-photo-elicitation as a data collection method. Fifteen participants (Twelve women and three men) shared 25 photographs and one video between the June 18 and August, 2020. Participants' photographs and texts were collected online. Data were analysed based on Thematic Analysis.

RESULTS

Three emerging categories were constructed: 1) the deconstruction of care: self-care and collective care 2) the crisis of care and gendered care, 2) beyond anthropocentrism: animalism and ecology. Findings indicate the need to understand "care" in terms of social reproduction, including self-care, care towards other humans and non-human animals, and collective care. Also, the need to care for planetary health and to be in contact with nature as a form of self-care and social care.

CONCLUSIONS

Care in a period of social and health crisis puts human relationships and also non-human life at the centre. Care requires adopting taking an ecological one-health perspective.

Designing an intervention to help the quitters quit: A qualitative, intervention co-design study

Objective

E-cigarettes are increasingly being provided by publicly funded stop smoking services. Our objectives were to understand the challenges and establish the means by which services could best support the use and subsequent discontinuation of e-cigarettes for this purpose.

Methods

Semi-structured interviews and co-design workshops with service users and providers of a stop smoking service.

Results

Thematic analysis was conducted. Interviews identified: 1. a reluctance to use e-cigarettes for cessation, 2. struggle to quit e-cigarettes (dependency, fear of relapse, compensatory "puffing") and 3. service development needs (consistency of approach). Co-design workshops suggested: 1. facilitation of e-cigarette use through understanding previous failed attempts, 2. offering a longer, two-staged approach to tobacco then e-cigarette cessation, careful timing of behavioural strategies and 3. enhanced communication between providers.

Conclusions

Our study suggests additional modifications to smoking cessation support measures when e-cigarettes are used for smoking cessation to address the challenges posed by public health guidance: "smokers should switch to vaping and vapers should stop smoking completely".

Innovation

Our study is the first to consider experiences of service users and providers about the challenges of using e-cigarettes for cessation; our co-design group of providers informed nine strategies needed to support this approach in practice.

A bridge to recovery: an interpretative phenomenological analysis with peer support specialists in Singapore

Recovery-oriented mental health care approach is gaining acceptance in Asian countries, including Singapore. Following Western countries, Singapore started hiring peer support specialists (PSS) as part of mental healthcare services. The aim of this paper was to explore and understand how individual peer support specialists in Singapore perceive and make sense of their role given their unique perspective as both recipients and providers of mental healthcare treatment. Six PSS in Singapore were interviewed utilizing a semi-structured interview schedule. Interviews were transcribed verbatim and analysed using interpretative phenomenological analysis. Four superordinate themes were generated illustrating how PSS viewed their role: embracing and embodying recovery, balancing on a bridge, impossible without support, and helping to end stigma. Findings also illustrated participants' awareness of the nature of the job and the role of PSS as still in the infancy stage. They embraced a recovery-oriented mindset despite experiencing stigma from professionals and/or their social support. The need to understand familial attitudes towards the PSS role is discussed. The limitations, contributions to the research, and several areas for future research are also outlined.

"What makes you well?" Supports of well-being in bipolar disorder. A qualitative study

OBJECTIVE

Subjective experience of people living with bipolar disorder is gaining attention in the field of research. Improving well-being could be as important as symptom remission, but this constitutes a vague concept. This study aimed at exploring the boundaries and the determinants of the well-being of people living with bipolar disorder in a French context.

METHODS

Individual semi-structured interviews were conducted with 16 patients by three professionals. Interviews were transcribed and analysed using the thematic analysis method.

RESULTS

Various dimensions emerged as contributing to well-being: daily routines, connectedness, regaining a positive identity, and self-awareness for self-management.

CONCLUSIONS

In addition to those common to the general population, this study highlighted specific determinants of well-being: the construction of a positive identity through acceptance of the diagnosis, the importance of self-awareness and self-management. They are highly intertwined with those of personal recovery and could help caregivers design interventions that directly target these goals. This study aimed to identify specific components of well-being for people living with bipolar disorder. Understanding the determinants of well-being enable caregivers to design tailored interventions that directly target quality of life and help improve bipolar disorder outcomes.

Understanding sexual health concerns among adolescents and young adults with differences of sex development: a qualitative study

PURPOSE

Differences of sex development (DSD) are congenital conditions that involve variations in individuals' sex chromosomes, genes, external and/or internal genitalia, hormones, and/or secondary sex characteristics. This study sought to elucidate the experiences of adolescents and young adults living with DSD by focusing on their experiences of intimacy and sexual health.

METHODS

An interpretative phenomenological research design was adopted. Semi-structured qualitative interviews were conducted with 11 Norwegian adolescents and young adults aged 16-26 years who had five different DSD conditions. The interview findings were analysed by means of a reflexive thematic analysis.

RESULTS

The participants reported feeling different, both in terms of how their body functioned and how their body looked. Lack of knowledge increased this feeling of differentness. Moreover, lack of everyday language with which to talk about intimacy and sexual concerns resulted in the participants feeling stigma. Anticipating stigmatization and lacking everyday language complicated the participants' communication regarding their DSD and sexual health.

CONCLUSIONS

The sexual experiences of adolescents and young adults with DSD are diverse. Fear of stigmatization and lack of everyday language complicate communication with healthcare professionals and others. Understanding their unique needs is crucial to helping individuals achieve good sexual health.

Expanding access to early medical abortion services in Ghana with telemedicine: findings from a pilot evaluation

Abortion in Ghana is legally permissible under certain conditions. Updated in June 2021, the National Comprehensive Abortion Care Services Standards and Protocols included telemedicine as a recognised option for early medical abortion (EMA). Subsequently, Marie Stopes Ghana launched this pilot project to understand the feasibility and acceptability of providing EMA services through telemedicine. The pilot evaluation drew on two research protocols - a process evaluation and a qualitative study. The process evaluation focused on existing routine data sources and additional pilot-specific monitoring, while the qualitative protocol included in-depth interviews with a range of key stakeholders, including telemedicine and in-person patients, healthcare managers, and service providers. Telemedicine for EMA is feasible, acceptable, and has likely expanded access to safe abortion in Ghana. The MSIG telemedicine service package enabled 97% of patients to have a successful EMA at home. Thirty-six per cent of the total 878 patients during the pilot reported that they had no other option for accessing an abortion. Patients described telemedicine EMA services as a highly acceptable and appealing service option. Eighty-four per cent reported they would opt for the telemedicine service again and 83% reported they were very likely to recommend the service. There is potential for telemedicine to expand and improve access to critical SRH services. EMA via telemedicine can be delivered effectively in a low-resource setting. This pilot also showed how telemedicine provides access to patients who feel they do not have other safe service options, meeting specific patient needs in terms of discretion, convenience, and timing.

"How is it going to help?": Exploring Black breast cancer patients' questions about biomarker testing to predict chemotherapy-induced peripheral neuropathy

Objective

Many Black breast cancer patients experience chemotherapy-induced peripheral neuropathy (CIPN). Our study assessed Black breast cancer patients' questions about a biomarker test that can predict likelihood of CIPN.

Methods

Nineteen Black women who were previous/current breast cancer patients participated in focus groups. Researchers briefly explained CIPN and the biomarker test, and then participants were asked what questions they would have about the test and its use in treatment decisions. These participant-voiced questions composed the data for this study and were analyzed using thematic analysis.

Results

Participants' questions centered on six themes: reasons for the test, effect on timeline of breast cancer treatment, testing procedure, limits of test (including accuracy), research done to develop this test (including research participants), and concerns about personal information connected to the test (including DNA).

Conclusion

This study provides an exploratory look at questions that Black breast cancer patients may have about toxicity biomarker testing use in breast cancer treatment decisions.

Innovation

These findings provide a starting point for developing patient-centered approaches for integrating this precision medicine tool into clinical care. The methodological choice to generate participants' questions (rather than answers to a question) led to robust, actionable data.

Finding a path in a methodological jungle: a qualitative research of resilience

Qualitative research provides an in-depth understanding of lived experiences. However, these experiences can be hard to apprehend by using just one method of data analysis. A good example is the experience of resilience. In this paper, the authors describe the chain of the decision-making process in the research of the construct of "resilience". s The authors justify the implications of a multi-method, pluralistic approach, and show how the triangulation of two or more qualitative methods and integration of several qualitative data analysis methods can improve a deeper understanding of the resilience among people with chronic pain. By combining the thematic analysis, narrative analysis, and critical incident technique, lived experiences can be seen from different perspectives.Therefore, the thematic analysis describes the content and answers to "what" regarding resilience, the narrative analysis describes the dynamics of resilience, and answers to "how", while the critical incident technique clarifies the most significant experience and the answers to "why" changes happen. This integrative approach could be used in the analysis of other psychological constructs and can serve as an example of how the rigour of qualitative research could be provided.

Patients' perspectives on digital health tools

Objective

Digital technology has changed the way healthcare is delivered and accessed. However, the focus is mostly on technology and clinical aspects. This review aimed to integrate and critically analyse the available knowledge regarding patients' perspectives on digital health tools and identify facilitators and barriers to their uptake.

Methods

A narrative review was conducted using the Scopus and Google Scholar databases. Information related to facilitators and barriers to uptake was synthesised and interpreted using thematic and content analyses, respectively.

Results

Seventy-one out of 1722 articles identified were eligible for inclusion. Patient empowerment, self-management, and personalisation were identified as the main factors that contributed to patient uptake in using digital health tools. Digital literacy, health literacy, and privacy concerns were identified as barriers to the uptake of digital health technology.

Conclusion

Digital health technologies have changed the way healthcare is experienced by patients. Research highlights the disconnect between the development and implementation of digital health tools and the patients they are created for. This review may serve as the foundation for future research incorporating patients' perspectives to help increase patients' engagement with emerging technologies.

Innovation

Participatory design approaches have the potential to support the creation of patient-centred digital health tools.

Experiences with physical activity, health and well-being among young adults with serious mental illness

PURPOSE

To explore how young adults with serious mental illness (SMI) experience physical activity and how these experiences influence their perceived health and well-being.

METHODS

Nine young adults with SMI who had participated in an aerobic high-intensity interval training program were interviewed in depth. The interviews were transcribed and subjected to reflexive thematic analysis.

RESULTS

The results indicated that people with SMI mainly experience physical activity as a meaningful activity that contributes to an increased sense of well-being and better health. However, to overcome various barriers, it is crucial to experience social support and encouragement. The following three main themes were identified through reflexive thematic analysis: (1) positive changes in focus and an increase in well-being occur through physical activity; (2) increased mental strength results from physical activity; and (3) a lack of support and feelings of safety prevent physical activity.

CONCLUSIONS

This study shows that adapted physical activity is an important resistance resource that can promote stronger self-identity, increased mental well-being and social engagement and thus contribute to an improved ability to manage stressors. Furthermore, the findings reveal that to engage in physical activity and promote sustainable life changes, it is important for individuals to choose a physical activity based on personal interest and meaning.

Looking through the lens: a photovoice study examining access to services for newcomer children

PURPOSE

Canadian new immigrant families (also known as newcomers) encounter challenges navigating systems when trying to access programmes critical for their children's healthy development. The purpose of this study is to understand how newcomer families find and use early childhood programmes and services from the perspective of families and early childhood educators (ECEs) working within a settlement organization.

METHODS

Using photovoice methodology, newcomer family members (n = 8) with young children and ECEs (n = 6) participated in a series of virtual workshops to share photos and reflect on their experiences.

RESULTS

Participants discussed the systemic barriers that obstructed newcomer families' access to services for young newcomer children. Financial challenges due to unemployment/underemployment, language and cultural differences were emphasized. Despite these barriers and challenges, participants shared how culturally responsive programmes enhanced their connections to programmes and services. Both groups of participants discussed the critical role of social networks in supporting newcomers to use programmes by helping families become aware of available services and assistance with various processes such as registration.

CONCLUSIONS

This research illustrates the lived experiences of newcomer families and identifies opportunities to address inequities, improve early childhood programmes, and enhance families' access to programmes and services.
