Randomized Controlled Trial
Dupilumab improves sense of smell and clinical outcomes in patients with severe chronic rhinosinusitis with nasal polyps with anosmia.
Loss of sense of smell is a cardinal symptom of chronic rhinosinusitis with nasal polyps (CRSwNP) and significantly impacts health-related quality-of-life. Dupilumab significantly improved smell outcomes (loss of smell [LoS] score; University of Pennsylvania Smell Identification Test [UPSIT]) versus placebo in the phase 3 SINUS-24/-52 studies (clinicaltrials.gov, NCT02898454/NCT02912468) in patients with severe CRSwNP. This post hoc analysis investigated the effect of dupilumab on olfaction using UPSIT smell impairment categories. ⋯ Most patients with severe CRSwNP had anosmia at baseline. Dupilumab treatment significantly improved smell versus placebo, with 14.9% achieving normosmia by week 24. There was a trend for better clinical outcomes in patients with greater smell improvement.

Breast cancer is a significant health challenge, with accurate and timely diagnosis being critical to effective treatment. Immunohistochemistry (IHC) staining is a widely used technique for the evaluation of breast cancer markers, but manual scoring is time-consuming and can be subject to variability. ⋯ We aim to identify the current state-of-the-art approaches, challenges, and potential future research prospects for this area of study. By conducting a comprehensive review of the existing literature, we aim to contribute to the ultimate goal of improving the accuracy and efficiency of breast cancer diagnosis and treatment.

Randomized Controlled Trial
Dapagliflozin reduces the white coat effect on systolic blood pressure of patients with type 2 diabetes: a post-hoc analysis from the ADDENDA-BHS 2 trial.
White coat effect (WCE) is a phenomenon linked to increased cardiovascular risk, where office blood pressure readings exceed home or ambulatory measurements. Excess weight and elevated blood pressure or glucose are associated with WCE in type 2 diabetes (T2D). This study compared dapagliflozin and glibenclamide on WCE in T2D patients under equivalent blood pressure and glucose control. ⋯ The trial was registered at the Clinicaltrials.gov (NCT: 02919345).

Review
Sting operations in biomedical publishing violate truthfulness and undermine trust in research.
Biomedical research cannot function without the trust of peers and society. The truthfulness of claims made by knowledge-producing agents, such as authors of research, is a prerequisite for their trustworthiness, and violations of truthfulness are rightly seen as a threat to the existence and validity of such research. While most reflection on the lack of truthfulness has focused on fake research, little attention has been paid to how sting operations and hoaxes arguably pose an equally great risk to the ethical integrity of publishing. ⋯ From a deontological perspective, we also argue that the reliance on anonymity in sting operations makes them just as bad, if not worse, than fake research. We advocate for critical scholarship as an alternative to hoaxes and sting operations to expose fake research, in order to promote truthfulness rather than violate it. Finally, we argue that journalists reporting on sting operations should insist less on their entertainment and sensationalist value, and focus more on their unethical nature.

Chronic cough (CC) symptoms can persist as refractory or unexplained CC (RCC). We sought to characterize the clinical and economic burden of RCC. ⋯ After adjusting for baseline differences, persistent symptoms of CC were associated with significantly higher comorbidity, healthcare resource use, and healthcare costs compared to CC that resolved. Effective treatments for RCC would thus be expected to result in improved health as well as substantial healthcare cost offsets.
