- BackgroundThe nocebo response refers to the phenomenon where non-specific factors, including negative verbal suggestion and treatment expectations, cause adverse events (AE) following a placebo treatment. Non-specific factors are also likely to influence AE occurrence following administration of active pharmacological treatments. ObjectiveThis meta-analysis aimed to estimate the nocebo response in dentistry by assessing the AEs prevalence in placebo- and active arms of randomised controlled trials (RCTs) assessing analgesic treatment following third molar (M3) surgery. MethodsA systematic search was performed in PubMed, Embase, Scopus, Web of Science and the Cochrane Central Register of Controlled Trials. Eligible studies had to report the number of patients experiencing at least one drug-related AE (patients with AE >= 1) separately for the active and placebo arms. The proportion of patients with AE >= 1 and drug-related dropouts were pooled, and risk differences (RDs) between patients in the placebo- and active arm were calculated. ResultsIn 50 independent RCTs of 47 identified articles, the pooled rates of patients with AE >= 1 were 22.8% in the placebo arm and 20.6% in the active arm. The pooled rates of drug-related dropout were 0.24% in the placebo arm and 0.08% in the active arm. There were no significant RDs in patients with AE >= 1 and drug-related dropouts. ConclusionThese results show that patients in the placebo arm reported AEs to the same extent as patients receiving active treatment, suggesting that most AEs in analgesic medication following M3 surgery may be attributed to the nocebo phenomenon.

- Evidence for the nocebo effect, a phenomenon characterised by suboptimal treatment efficacy, worsening of symptoms, or the occurrence of adverse events caused by an individual's negative treatment expectations, is growing across a multitude of medical fields. Within dentistry, little attention has been paid to patients' negative expectations, despite a number of studies supporting the influence of related factors, such as dental fear and anxiety, on the severity of peri- and post-operative dental pain. Only recently, a small number of commentaries and letters have emerged, urging dentists to recognise the possible existence of nocebo effects in dentistry and its implications for patient care. The present review summarises essential evidence of the nocebo phenomenon especially in relation to pain and drug administration. Subsequently, an overview of the current evidence of the nocebo phenomenon in the dental field is presented. Finally, based on the general knowledge of the nocebo effect, the review indicates fruitful arrays of research into the nocebo effect in dentistry.

- Objective: To explore the experiences and views of Norwegian Municipality Chief Medical Officers (MCMOs) on preparedness, collaboration, and organization during the COVID-19 pandemic to gain insight into local crisis management of value for future pandemic responses. Design: Longitudinal qualitative interview study. We conducted semi-structured digital interviews with nine MCMOs working in different municipalities in Norway from September to December 2020. Five MCMOs were re-interviewed from January to April 2021. We used thematic analysis to analyze the data. Results: Through the analysis, three major themes were identified in the material; 1) The view of preparedness changed from being low-priority and dormant to the desire to strengthen preparedness as a permanent measure; 2) The nature of the pandemic forced a change in internal and external communication and collaboration for the MCMOs towards direct dialogue, teamwork and digital networking; 3) The pandemic changed the role and position of the MCMO within the municipal organization. Although most MCMOs were given a leading role in the municipal pandemic response, some MCMOs experienced that they were not positioned to fully exercise their intended role. In our material, de-authorization of the MCMO role seemed to coincide with the increasing size and organizational complexity of the municipality. Conclusions: The Norwegian pandemic response and outcome have been regarded as successful internationally. Although the MCMOs managed to implement flexible and quick responses facilitated by teamwork, dialogue, and joint sensemaking, they also identified several challenges and shortcomings of the Norwegian pandemic preparedness requiring organizational and financial changes to sustain future health system resilience.

Tidskriftsartikel (refereegranskat)abstract
- Control interventions (often called "sham," "placebo," or "attention controls") are essential for studying the efficacy or mechanism of physical, psychological, and self-management interventions in clinical trials. This article presents core recommendations for designing, conducting, and reporting control interventions to establish a quality standard in non-pharmacological intervention research. A framework of additional considerations supports researchers' decision making in this context. We also provide a reporting checklist for control interventions to enhance research transparency, usefulness, and rigour.
