The contribution of primary care practitioners to interventions reducing loneliness and social isolation in older people—An integrative review

Background

Social connection is a fundamental human need. Its absence can lead to loneliness and social isolation, adversely impacting health and well-being. Given their regular contact and trusted relationships with older people, practitioners delivering community-based primary care are well-positioned to address this issue. However, their contribution to addressing loneliness and social isolation is unclear.

Aim

This integrative review explores the contribution of the primary care workforce to interventions aimed at reducing loneliness and social isolation in community-dwelling older people.

Method

Using an integrative review method, Scopus, Web of Science, CINAHL and PubMed were searched for original research published between 2000 and 2022. Fourteen papers reporting 13 primary studies were appraised for methodological quality and included in the review. Data were extracted into a summary table and analysed using thematic analysis.

Results

Included studies came from over six countries. Internationally, primary care services have diverse structures, funding and workforces influencing their response to loneliness and social isolation. All but one intervention was multi-component, with ten studies including a group-based activity and three providing primarily individual-level activities. Only six studies reported reductions in loneliness following the intervention. Three themes were identified: characteristics of interventions; implementation context, barriers and facilitators; and differing contributions of primary care practitioners in addressing loneliness and social isolation of older people.

Conclusion

There is increasing demand and scope for primary care practitioners to assist lonely and socially isolated older people. It is important to understand how to equip and incentivise these practitioners to routinely identify, assess and respond to lonely and socially isolated older people despite varying implementation contexts. There is a need for further research that explores how the primary care team can be better utilised to deliver effective interventions that reduce the health impacts of loneliness and social isolation.     

骨髓增生异常综合征患者的asxli基因变异分析

目的探讨骨髓增生异常综合征(myelodysplastic syndromes,MDS)患者ASXL1基因变异的发生情况及其与其他基因变异和部分临床参数之间的相关性。方法采用PCR扩增产物直接测序法检测149例MDS患者ASXU、U2AF1、SF3B1、DNMT3A、TET2、IDH1/2、NPM1、FLT3-ITD.C-KIT等基因的变异情况。结果在149例患者中,ASXU基因变异的检出率为24.8%(37/149),变异率>5%的基因分别是U2AF1(22.8%)、TET2(11.4%)、DNMT3A(9.4%)、NPM1(8.1%).SF3B1(6.0%)。ASXL1变异最常见的共存变异基因为U2AF1(27.0%,10/37)及TET2(18.9%,7/37)。ASXL1变异组与野生组患者在中位年龄、MDS亚型、染色体核型、外周白细胞、血红蛋白、血小板水平及骨髓原始细胞计数等方面的差异均无统计学意义(P>0.05)o对29例ASXL1变异患者进行了有效的随访,其中11例进展为急性髓系白血病(acute myeloid leukemia,AML),白血病转化率为37.9%。在92例野生型患者中,13例进展为AML,白血病转化率为14.1%。ASXL1变异组白血病转化率明显高于野生组,差异有统计学意义(PV 0.01)。结论ASXL1变异在MDS中有较高的发生率,并常与U2AF1及TET2基因变异共存,伴有该变异的患者具有更高的白血病转化率。     

IMPROVEMENT IN WALKING PERFORMANCE OF CHILDREN WITH CEREBRAL PALSY: PRELIMINARY RESULTS

The effect of four to six months use of ankle-foot orthoses (AFOs) and balance training was determined for six children with cerebral palsy. The six consecutively referred patients had spastic diplegia or hemiplegia, with hyperextension of the knee, and had accurate voluntary control of the trunk and hips. Fixed AFOs were adjusted to control the position of the ground reaction force in relation to the knees. Balance training was targeted to the knees. All children showed a decrease in the magnitude of the knee-extending moment arm toward normal when barefoot. Improvement was noted in foot-ground contact for three children and of stance-phase posture for three. These improvements were not related to range of motion or speed, and a motor learning effect is proposed. The value of monitoring the moment arm is emphasised.     

Family presence during resuscitation and invasive procedures

The practice of allowing family to be present during patient resuscitation or invasive procedures (Family Presence) is gaining acceptance in North America and the United Kingdom in controlled circumstances. Research into Family Presence has demonstrated multiple benefits for the patient, family and health care team. These advantages include helping the family to understand the severity of the illness/trauma and to see that appropriate attempts were undertaken to save their loved one. Family Presence can also facilitate improved communication between the health care team and family. In spite of evidence supporting Family Presence as a useful practice for patient, family and health care team, the use of Family Presence is uncommon within Australian emergency departments and hospitals. Clear expectations at organisational, governmental and professional levels are essential to effectively implement this approach. To be supported in the clinical area, the success of a Family Presence program requires an inclusive approach to program development. A critical component of a successful Family Presence program is a family facilitator who is adequately prepared for the role and committed to supporting the family during resuscitation or invasive procedures. Research exploring Family Presence in Australia is lacking and highlights the need for context specific research in this area.     

Use of E mu-PIM-1 transgenic mice short-term in vivo carcinogenicity testing: lymphoma induction by benzo[a]pyrene, but not by TPA

E mu-pim-1 transgenic mice are predisposed to develop lymphomas. Due to their low spontaneous tumour incidence and their increased sensitivity towards the lymphomagen ethylnitrosourea these mice may present an interesting model for short-term carcinogenicity testing. Here, we report on the further exploration of this transgenic mouse model with two additional carcinogens known to have, among others, the lymphohaematopoietic system as target, i.e. benzo[a]pyrene (B[a]P) and 12-O-tetradecanoylphorbol-13-acetate (TPA). B[a]P, given three times a week (by gavage) for 13 weeks at 4.3, 13 or 39 mg/kg body weight, resulted in a dose-related increase in lymphomas up to a 90% incidence in E(mu)-pim-1 mice during the observation period of 40 weeks. B[a]P also induced tumours of the forestomach within this observation period, though at a lower incidence and apparently equally effective in wildtype and transgenic mice. TPA, on the other hand, was unable to induce lymphomas (or tumours in any other organ) in either transgenic or wildtype animals within the observation period of 44 weeks, when applied dermally at the maximum tolerated dose of 3 microg/mouse, twice a week for 35 weeks. Molecular analysis showed that B[a]P-induced lymphomas in transgenic mice were of T-cell origin, 80% of which had elevated levels of c-myc expression. None of the lymphomas had increased N-myc expression and mutation analysis of the ras-gene family revealed a K-ras mutation in only one out of eight tumours investigated. Also, none of the lymphomas showed aberrant expression of p53 as determined by immunohistochemistry. It is concluded that the E mu-pim-1 mouse model will not be very suitable for short-term carcinogenicity testing in general: only genotoxic chemicals that have the lymphohaematopoietic system as target for carcinogenesis in wild- type mice, appear to be efficiently identified.      

Thoracic empyema: a study of 56 patients

Fifty seven children with thoracic empyema (37 boys and 20 girls) aged less than 12 years were seen at the University of Port Harcourt Teaching Hospital between January 1989 and December 1991. Staphylococcus aureus was the most common organism isolated from the pus of these patients (36 (63%) patients). Pseudomonas aeruginosa, the next most common organism, was isolated in 10 (18%) patients. The most common symptoms at presentation were acute illness with fever and cough (51 (89%) patients). All the patients were treated with closed intercostal tube drainage and appropriate antibiotics. Decortication was resorted to in only one patient. There were two deaths and the overall survival rate was 97%.     

Is caring the ethical ideal?

This paper will examine the claim that caring is an appropriate ethical ideal for nursing. Initially it will examine nursing's philosophy of care and caring, highlighting some areas of difficulty and dissatisfaction articulated by many of its contemporary theorists Evaluation of the notion of caring as an appropriate ethical ideal for nursing will be balanced against those in opposition, and in this process their critique will be discussed This discussion will focus on areas such as virtue, virtue ethics, moral responsibility, feminine values, mothering and the debate between male and female caring Different forms of caring will be evaluated and balanced against different forms of nursing The paper will then suggest that current views which hold aloft nursing as a bedmate of caring may be detrimental to both the cared-for and the carer, advocating in the process a move toward change     

Establishing good practices in continuing care: a descriptive study of community nursing services for people with HIV infection

This paper presents findings from a 2-year study of community nursing services for people affected by HIV infection in six health authorities in England The research, commissioned by the Department of Health, England, aimed to identify the main bridges and barriers to effective home nursing care, focusing on discharge co-ordination, district nursing and multi-agency collaboration Using a triangulated, case study approach, the main methods of data collection included non-participant observation, case note analysis, semi-structured staff interviews, a postal questionnaire of district nurses and a series of focus groups with service users Study sites included three cities and surrounding districts in the north west, north and south east of England Findings suggest there is considerable room for improvement in discharge planning and that good practice is not the preserve of specialist units District nurses are shown to be willing providers of the majority of home nursing care to this client group, but there is a need for more focused training, greater use of care co-ordinators and more emotional and managerial support
