Abstract
OBJECTIVE To evaluate the use of custom-made insoles adapted to flip-flops on pain intensity, foot function, and functional walking ability in individuals with persistent plantar heel pain in the short and medium term. DESIGN Randomised controlled trial. SETTING Flip-flop sandals in patients with persistent plantar heel pain. MAIN MEASURES Participants (n = 80) were assessed at baseline, six and 12 weeks after the intervention, and 4 weeks post-intervention. RESULTS For the primary outcomes, after 6 weeks of intervention, no between-group difference was observed in the intensity of morning pain or pain with walking, mean difference = -0.4 (95% confidence intervals = -1.5 to 0.8). Similarly, after 12 weeks of intervention, no between-group difference was observed in the intensity of morning pain or pain with walking, mean difference = -0.7 (95% confidence intervals = -1.9 to 0.6). Finally, at 4 weeks after the end of the intervention, there was no between-group difference in morning pain or pain on walking, mean difference = 0.01 (95% confidence intervals = -1.4 to 1.4). All differences and confidence intervals were smaller than the minimum clinically important difference for pain (2 points). There were no differences between the groups for the secondary outcomes. In addition, the mean differences were smaller than the minimum clinically important differences for pain intensity, foot function and functional walking ability. CONCLUSION Custom-made insoles fitted to flip-flops did not differ from flip-flops with sham insoles in improving pain intensity, foot function and functional walking ability in people with persistent heel pain.Trial registration: ClinicalTrials.gov (Identifier: NCT04784598). Data of registration: 2023-01-20.

Abstract
The "red potion," inspired by video games, emulates the health point replenishment mechanism for injured game characters. Conversely, red ginger, known for its potential tonic properties in enhancing cardiovascular endurance, poses challenges in acquisition within specific regions. Several previous studies have highlighted the existence of an inseparable link when gamers are engaged in real-world activities, even without actively playing the game in the virtual world. This suggests the potential for the "red potion" concept to enhance the well-being of gamers in reality. A statistical ANOVA experiment involved 90 participants, all avid gamers, categorized into three groups: basic, placebo, and experimental. The basic group (BG) received a red-colored beverage without red ginger infusion or the 'red potion' concept. In contrast, the placebo group (PG) received a similar beverage described as a "red potion" but without red ginger. Lastly, the experimental group (EG) received a red ginger-infused beverage without the "red potion" concept. Despite receiving different treatments, all beverages were presented in the same red color. Participants underwent the "beep test" to assess their baseline stamina. The results revealed that both PG and EG exhibited comparable cardiovascular endurance, affirming the potential of the "red potion" concept to positively influence gamers.

Abstract
Suggestions about hunger can generate placebo effects on hunger experiences. But, the underlying neurocognitive mechanisms are unknown. Here, we show in 255 women that hunger expectancies, induced by suggestion-based placebo interventions, determine hunger sensations and economic food choices. Functional magnetic resonance imaging in a subgroup (n = 57/255) provides evidence that the strength of expecting the placebo to decrease hunger moderates medial prefrontal cortex activation at the time of food choice and attenuates ventromedial prefrontal cortex (vmPFC) responses to food value. Dorsolateral prefrontal cortex activation linked to interference resolution formally mediates the suggestion-based placebo effects on hunger. A drift-diffusion model characterizes this effect by showing that the hunger suggestions bias participants' food choices and how much they weigh tastiness against the healthiness of food, which further moderates vmPFC-dlPFC psychophysiological interactions when participants expect decreased hunger. Thus, suggestion-induced beliefs about hunger shape hunger addressing economic choices through cognitive regulation of value computation within the prefrontal cortex.

Abstract
INTRODUCTION The management of fibromyalgia involves a combination of pharmacological and non-pharmacological treatments. SOURCE OF DATA Recently published literature in PubMed, Google Scholar and Embase databases. AREAS OF AGREEMENT Several pharmacological and non-pharmacological strategies have been proposed for the management of fibromyalgia. However, the management of fibromyalgia remains controversial. The administration of placebo has proved to be more effective than no treatment in many clinical settings and evidence supports the 'therapeutic' effects of placebo on a wide range of symptoms. AREAS OF CONTROVERSY The placebo effect is believed to impact the clinical outcomes, but its actual magnitude is controversial. GROWING POINTS A meta-analysis comparing pharmacological management versus placebo administration for fibromyalgia was conducted. AREAS TIMELY FOR DEVELOPING RESEARCH Drug treatment resulted to be more effective than placebo administration for the management of fibromyalgia. Nevertheless, placebo showed a beneficial effect in patients with fibromyalgia. Treatment-related adverse events occurred more frequently in the drug treatment. LEVEL OF EVIDENCE I, Bayesian network meta-analysis of double-blind randomized clinical trials.

Abstract
Background: The efficacy of antifungals for onychomycosis has been determined in randomized controlled trials (RCTs); interestingly their control arms have demonstrated some therapeutic effects. These controls constitute either placebos (inert pills) or vehicles (all but the antifungal component of the creams). The objective of this research was to determine (i) whether RCT controls exhibited statistically-relevant efficacy rates (i.e. beyond the "placebo effect"), (ii) whether oral and topical controls differed in their efficacies, and (iii) if the efficacy rates of the controls correlated with those of the active comparator associated with that control. Methods: RCTs of oral and topical monotherapies for dermatophyte toenail onychomycosis were identified through a systematic literature search. For our meta-analyses of cure rates the double arcsine transformation was used. The N-1 chi squared test was used to determine whether the cure rates significantly differed between topical and oral controls. Correlation was investigated using Kendall rank correlation tests. Results: The pooled mycological, complete, and clinical cure rates of all control interventions (n = 19 trials) were 9%, 1%, and 6%, respectively. The pooled efficacy rates for oral and topical controls were: mycological cure rate, 7% and 12% (p=0.0016); complete cure rate, 1% for both; and clinical cure rate, 4% and 8%, respectively (p=0.0033). For oral RCTs, the respective cure rates of the active therapies were not correlated with controls. However, for topical RCTs, as the mycological and clinical cure rates of the active therapy increased, so did those of the topical vehicle associated with the active therapy in question, and vice versa. Conclusions: The topical vehicle cure rates were often higher than the oral placebo cure rates, likely due to the presence of non-antifungal chemicals (e.g. moisturizers, urea) with antifungal and debriding properties, which are not present in oral controls. .
