Optical coherence tomography angiography indicates subclinical retinal disease in neuromyelitis optica spectrum disorders.

BACKGROUND: Neuromyelitis optica spectrum disorders (NMOSD) are neuroinflammatory diseases of the central nervous system. Patients suffer from recurring relapses and it is unclear whether relapse-independent disease activity occurs and whether this is of clinical relevance. OBJECTIVE: To detect disease-specific alterations of the retinal vasculature that reflect disease activity during NMOSD. METHODS: Cross-sectional analysis of 16 patients with NMOSD, 21 patients with relapsing-remitting multiple sclerosis, and 21 healthy controls using retinal optical coherence tomography (OCT), optical coherence tomography angiography (OCT-A), measurement of glial fibrillary acidic protein (GFAP) serum levels, and assessment of visual acuity. RESULTS: Patients with NMOSD but not multiple sclerosis revealed lower foveal thickness (FT) (p = 0.02) measures and an increase of the foveal avascular zone (FAZ) (p = 0.02) compared to healthy controls independent to optic neuritis. Reduced FT (p = 0.01), enlarged FAZ areas (p = 0.0001), and vessel loss of the superficial vascular complex (p = 0.01) were linked to higher serum GFAP levels and superficial vessel loss was associated with worse visual performance in patients with NMOSD irrespective of optic neuritis. CONCLUSION: Subclinical parafoveal retinal vessel loss might occur during NMOSD and might be linked to astrocyte damage and poor visual performance. OCT-A may be a tool to study subclinical disease activity during NMOSD.

Horizontal and vertical targeting: a population-based comparison of public eldercare services in urban and rural areas of Sweden.

The concepts of target efficiency can be used to assess the extent to which service provision is in line with the needs of the population. Horizontal target efficiency denotes the extent to which those deemed to need a service receive it and vertical target efficiency is the corresponding extent to which those who receive services actually need them. The aim of this study was to assess the target efficiency of the Swedish eldercare system and to establish whether target efficiencies differ in different geographical areas such as large urban, midsize urban and rural areas. Vertical efficiency was measured by studying those people who received eldercare services and was expressed as a percentage of those who received services who were functionally dependent. To measure horizontal target efficiency, data collected at baseline in the longitudinal population study SNAC (Swedish National study on Aging and Care) during the years 2001-2004 were used. The horizontal efficiency was calculated as the percentage of functionally dependent persons who received services. Functional dependency was measured as having difficulty with instrumental activities of daily living (IADL) and/or personal activities of daily living (PADL). Services included long-term municipal eldercare services (LTC). Horizontal target efficiency for the public LTC system was reasonably high in all three geographical areas, when using dependency in PADL as the measure of need (70-90 %), but efficiency was lower when the less restrictive measure of IADL dependency was used (40-50 %). In both cases, the target efficiency was markedly higher in the large urban and the rural areas than in the midsize urban areas. Vertical target efficiency showed the same pattern-it was almost 100 % in all areas for IADL dependency, but only 50-60 % for PADL dependency. Household composition differed in the areas studied as did the way public long-term care was provided to people living alone as compared to those co-habiting.

Older people's experience of utilisation and administration of medicines in a health- and social care context.

BACKGROUND: People living at home who lack ability to manage their medicine are entitled to assistance to improve adherence provided by a home care assistant employed by social care. AIM: The aim was to describe how older people with chronic diseases, living at home, experience the use and assistance of administration of medicines in the context of social care. DESIGN: A qualitative descriptive study. METHODS: Ten participants (age 65+) living at home were interviewed in the participants' own homes. Latent content analysis was used. FINDINGS: The assistance eases daily life with regard to practical matters and increases adherence to a medicine regimen. There were mixed feelings about being dependent on assistance; it interferes with self-sufficiency at a time of health transition. Participants were balancing empowerment and a dubious perception of the home care assistants' knowledge of medicine and safety. Physicians' and district nurses' professional knowledge was a safety guarantee for the medicine process. CONCLUSIONS: Assistance eases daily life and medicine regimen adherence. Dependence on assistance may affect self-sufficiency. Perceived safety varied relating to home care assistants' knowledge of medicine. RELEVANCE TO CLINICAL PRACTICE: A well-functioning medicine assistance is crucial to enable older people to remain at home. A person-centred approach to health- and social care delivery is efficient and improve outcome for the recipient of care.

Targeting cancer with small-molecule pan-KRAS degraders.

Mutations in the Kirsten rat sarcoma viral oncogene homolog (KRAS) protein are highly prevalent in cancer. However, small-molecule concepts that address oncogenic KRAS alleles remain elusive beyond replacing glycine at position 12 with cysteine (G12C), which is clinically drugged through covalent inhibitors. Guided by biophysical and structural studies of ternary complexes, we designed a heterobifunctional small molecule that potently degrades 13 out of 17 of the most prevalent oncogenic KRAS alleles. Compared with inhibition, KRAS degradation results in more profound and sustained pathway modulation across a broad range of KRAS mutant cell lines, killing cancer cells while sparing models without genetic KRAS aberrations. Pharmacological degradation of oncogenic KRAS was tolerated and led to tumor regression in vivo. Together, these findings unveil a new path toward addressing KRAS-driven cancers with small-molecule degraders.

District nurses' perceptions of the concept of delegating administration of medication to home care aides working in the municipality: a discrepancy between legal regulations and practice.

AIMS AND OBJECTIVES: To describe district nurses' perceptions of the concept of delegating medication management to unlicensed personnel working in municipal social care. BACKGROUND: The delegation of medical tasks involves responsibility and is regulated by law to avoid damage and injuries and to protect the patient. The delegation of the administration of medication is a multifaceted task. The delegating district nurse is responsible for the outcome and should also follow up the delegated task. DESIGN: A descriptive qualitative study, involving semi-structured interviews and content analysis. METHODS: Twenty district nurses were interviewed. The interviews were audio taped. The data were collected from April 2009-August 2010 and analysed using content analysis. RESULTS: The findings revealed that the statutes of delegation appear to be incompatible with practice, however, mostly due to lack of time. Communication between district nurses and home care aides, as well as tutoring, was regarded as important. The district nurses found it imperative to be available to the home care aides and made an effort to create a trusting atmosphere. CONCLUSIONS: District nurses cannot manage their workload without delegating the administration of medication in the present organisational model of health care and social care. The statutes regarding delegating medicine tasks are also cumbersome and difficult to incorporate for district nurses who are responsible for the delegation. RELEVANCE TO CLINICAL PRACTICE: The findings elucidate the current situation as regards district nurses and the need to delegate the administration of medication. Health care and social care for home-dwelling older patients, as well as statutes, needs to be evaluated and updated to meet and be prepared for the increasing demands of care.

Epidemiology of Alzheimer's disease: occurrence, determinants, and strategies toward intervention.

More than 25 million people in the world today are affected by dementia, most suffering from Alzheimer's disease. In both developed and developing nations, Alzheimer's disease has had tremendous impact on the affected individuals, caregivers, and society. The etiological factors, other than older age and genetic susceptibility, remain to be determined. Nevertheless, increasing evidence strongly points to the potential risk roles of vascular risk factors and disorders (eg, cigarette smoking, midlife high blood pressure and obesity, diabetes, and cerebrovascular lesions) and the possible beneficial roles of psychosocial factors (eg, high education, active social engagement, physical exercise, and mentally stimulating activity) in the pathogenetic process and clinical manifestation of the dementing disorders. The long-term multidomain interventions toward the optimal control of multiple vascular risk factors and the maintenance of socially integrated lifestyles and mentally stimulating activities are expected to reduce the risk or postpone the clinical onset of dementia, including Alzheimer's disease.

Nurses' experiences of health concerns, teamwork, leadership and knowledge transfer during an Ebola outbreak in West Africa.

AIM: To describe nurses' experiences of health concerns, teamwork, leadership and management and knowledge transfer during an Ebola outbreak in West Africa. DESIGN: The study has a qualitative descriptive design. METHODS: The 44 nurses who had worked in an Ebola Treatment Centre in Kenema in 2014 and 2015 were invited by email to respond to a questionnaire. The qualitative, open-ended answers were analysed using a thematic analysis. Data have been coded systematically, with the identification of semantic patterns presented in four themes. RESULTS: The themes are as follows: personal health management-a way to feel safe and secure for delegates and affiliates; pre-deployment training-crucial for a joint value base and future collaboration; the importance of a professional democratic approach and being a good role model; and the value of timely in-depth knowledge transfer of experienced former delegates.

Higher education as a platform for capacity building to address violence against women and promote gender equality: the Swedish example.

Violence against women is an acknowledged public and global health problem which has adverse consequences for women's health. Education, especially higher education, has long been identified as an important arena for addressing the problem and promoting gender equality. Two measures recently put in place in the Swedish higher education have brought the role of the sector into focus. The first is the inclusion of gender equality as a measurable outcome in quality assurance in higher education. The second measure is the amendment of the Swedish Higher Education Ordinance to include mandatory knowledge of VAW in the degree programme of seven selected relevant professional groups. The potentials of both measures to positively contribute to the gender equality discourse, as well as improving capacity building for the public health workforce who encounter VAW, are discussed.

Prevention of Alzheimer's disease and dementia. Major findings from the Kungsholmen Project.

The aging of the population is a worldwide phenomenon, and studying age-related diseases has become a relevant issue from both a scientific and a public health perspective. This review summarises the major findings concerning prevention of Alzheimer's disease (AD) and other dementias from a population-based study, the Kungsholmen Project. The study addresses risk- and protective factors for AD and dementia from a lifetime perspective: at birth, during childhood, in adult life, and in old age. Although many aspects of the dementias are still unclear, some risk factors have been identified and interesting hypotheses have been suggested for other putative risk or protective factors. At the moment it is also possible to delineate some preventative strategies for dementia.

Global nursing in an Ebola viral haemorrhagic fever outbreak: before, during and after deployment.

BACKGROUND: Nurses are on the forefront and play a key role in global disaster responses. Nevertheless, they are often not prepared for the challenges they are facing and research is scarce regarding the nursing skills required for first responders during a disaster situation. OBJECTIVES: To investigate how returnee nursing staff experienced deployment before, during and after having worked for the Red Cross at an Ebola Treatment Center in Kenema, West Africa, and to supply knowledge on how to better prepare and support staff for viral haemorrhagic fever outbreaks. METHODS: A descriptive, cross-sectional approach. Questionnaires were administered to nurses having worked with patients suffering from Ebola in 2014 and 2015. Data collection covered aspects of pre-, during and post-deployment on clinical training, personal health, stress management, leadership styles, socio-cultural exposure and knowledge transfer, as well as attitudes from others. Data was analysed using both quantitative and qualitative methods. RESULTS: Response-rate was 88%: forty-four nurses from 15 different countries outside West Africa answered the questionnaire. The respondents identified the following needs for improvement: increased mental health and psychosocial support and hands-on coping strategies with focus on pre- and post-deployment; more pre-deployment task-oriented clinical training; and workload reduction, as exhaustion is a risk for safety. CONCLUSIONS: This study supplies knowledge on how to better prepare health care staff for future viral haemorrhagic fever outbreaks and other disasters. Participants were satisfied with their pre-deployment physical health preparation, whereas they stressed the importance of mental health support combined with psychosocial support after deployment. Furthermore, additional pre-clinical training was requested.
