Behavioural insights and the evolving COVID-19 pandemic

Behavioural sciences have complemented medical and epidemiological sciences in the response to the SARS-CoV-2 pandemic. As vaccination uptake continues to increase across the EU/EEA – including booster vaccinations – behavioural science research remains important for both pandemic policy, planning of services and communication. From a behavioural perspective, the following three areas are key as the pandemic progresses: (i) attaining and maintaining high levels of vaccination including booster doses across all groups in society, including socially vulnerable populations, (ii) informing sustainable pandemic policies and ensuring adherence to basic prevention measures to protect the most vulnerable population, and (iii) facilitating population preparedness and willingness to support and adhere to the reimposition of restrictions locally or regionally whenever outbreaks may occur. Based on mixed-methods research, expert consultations, and engagement with communities, behavioural data and interventions can thus be important to prevent and effectively respond to local or regional outbreaks, and to minimise socioeconomic and health disparities. In this Perspective, we briefly outline these topics from a European viewpoint, while recognising the importance of considering the specific context in individual countries.     

GP strategies to avoid imaging overuse. A qualitative study in Norwegian general practice

ObjectivesThe aim of the study was to identify general practitioners’ (GPs) strategies to avoid unnecessary diagnostic imaging when encountering patients with such expectations and to explore how patients experience these strategies.Design, setting and subjectsWe conducted a qualitative study that combined observations of consultations and interviews with GPs and patients. A total of 24 patients visiting nine different GPs in two Norwegian urban areas were included in the study. Of these, 12 consultations were considered suitable for studying GP strategies and were therefore selected for a more thorough analysis.Main outcome measuresGPs’ communication strategies to avoid unnecessary medical imaging and patients’ experiences with such strategies.ResultsFive categories of strategies were identified: (1) wait and see – or suggest an alternative; (2) the art of rejection; (3) seek support from a professional authority; (4) partnership and shared decision-making and (5) reassurance, normalisation and recognition. The GPs often used multiple strategies. Factors related to a long-term doctor–patient relationship seemed to influence both communication and how both parties experienced the decision. Three important factors were evident: the patient trusted the doctor, the doctor knew the patient’s medical history and the doctor knew the patient as a person. The patients seemed to be generally satisfied with the outcomes of the consultations.ConclusionGPs largely combine different strategies when meeting patients’ expectations of diagnostic imaging that are not strictly medically indicated. Continuity of the doctor–patient relationship with good personal knowledge and trust between doctor and patient appeared crucial for patients to accept the doctors'' decisions.

Key points

• GPs usually combine a broad range of strategies to avoid unnecessary medical imaging
• The patients appeared generally satisfied regardless of the strategy the strategy used by the GPs and even where their referral request were rejected
• Factors related to a long-term doctor–patient relationship appeared decisive

     

The in vitro antioxidant properties of the Al-quercetin/βCD and Al-catechin/βCD inclusion compounds, rationalized in terms of their electrochemical behaviour

Inclusion compounds of Al-quercetin and Al-catechin complexes with β-cyclodextrin (βCD) were investigated. The complex and the inclusion compound of quercetin are more effective DPPH^? scavengers than the corresponding catechin compounds and the inclusion does not compromise their scavenging abilities, with only a slight decrease in the EC₅₀ values. This is in accordance with the electrochemical data, which revealed that the inclusion compounds have lower diffusion coefficients in aqueous solution than the non-included compounds. For the quercetin compounds, some spectroscopic properties were also addressed by means of UV–visible and NMR measurements in aqueous media.     

Effectiveness of nursing interventions in heart failure patients in home care using NANDA-I,NIC, and NOC

ObjectiveThe objective of the study is to evaluate the effectiveness of nursing interventions (NIC) using nursing outcomes (NOC) and based on NANDA-I nursing diagnoses in patients with heart failure in home care.MethodIn this longitudinal study, 23 patients with heart failure were followed for 6 months, in four home visits. During the visits, nursing diagnoses were established, outcomes assessed, and interventions implemented.ResultsOf the 11 NIC interventions implemented, eight proved effective, that is, showed significant improvement between the first and the fourth visit, according to scores obtained for six outcomes: knowledge: treatment regimen, knowledge: medication, compliance behavior, symptom control, activity tolerance, and energy conservation.ConclusionNIC interventions health education, self-modification assistance, behavior modification, teaching: prescribed medication, teaching: disease process, nutritional counseling, telephone consultation, and energy conservation showed effective outcomes based on NOC scores, suggesting that the NANDA-I, NIC, and NOC linkage is useful in patients with heart failure in home care.     

Auxiliary liver transplantation in acute liver failure in the rat – an illustrated description of a new surgical approach

INTRODUCTION: To investigate auxiliary liver transplantation successfully in rats suffering from acute liver failure, we developed a new surgical approach. METHODS: A 70% hepatectomized liver graft was implanted into the right upper quadrant of the abdomen. The donor portal vein was anastomosed with the recipient's right renal artery using the splint technique. The donor infrahepatic vena cava was attached onto the recipient vena cava end to side. The bile duct was implanted into the duodenum.
