Article Abstract
Objective: To evaluate the efficacy of various pharmacological treatments for olfactory disorders in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).
Data Sources: PubMed, Embase, Cochrane Library, and Web of Science.
Methods: We searched the related literature in PubMed, Embase, Cochrane Library, and Web of Science up to Aug 2024 to appraise the effects of pharmacotherapy on olfactory sensation. After that, two reviewers independently screened the retrieved articles, extracted the pertinent data, and assessed the risk of bias in the included studies. Then we used Stata 14.2 to perform a network meta-analysis.
Results: Ninteen randomized controlled trials (RCTs) and 2354 participants were included. Compared with placebo, biologics demonstrated the most significant improvement in subjective olfactory dysfunction (OD) [standardized mean difference (SMD) = -0.75, 95% confidence intervals (CI) (-1.08, -0.41)]. In terms of objective olfactory function improvement, biologics also exhibited the greatest effect (SMD = 0.93, 95% CI [0.56, 1.31]). Among various biologics, dupilumab was the most effective in alleviating both subjective OD (SMD = -1.30, 95% CI [-1.51, -1.09]) and objective OD (mean difference [MD] = 11.13, 95% CI [9.91, 12.35]).
Conclusions: Our research results indicated that biologics might show better performance in terms of improving the olfactory sensation of patients with CRSwNP, particularly dupilumab. However, given the limitations of this study, future research should employ more standardized olfactory assessment methods and conduct more large-scale RCTs, ultimately guiding clinicians and patients in making informed and optimal treatment choices.
Level Of Evidence: NA.

Background: Olfactory training (OT) has been proposed as a non-pharmacological intervention to improve cognitive functions and depressive symptomatology, but evidence remains fragmented.
Methods: In this study, we conducted a systematic review and meta-analysis of randomised controlled trials (RCTs) comparing OT versus control in middle-aged and elderly adults. Four databases (PubMed, Cochrane Library, Web of Science, Embase) were systematically searched from database inception through June 2025.

Background: Taste and smell disorders are more common in individuals with diabetes, particularly among those with low insulin sensitivity or central obesity. These disorders may affect glycaemic control by altering dietary habits. This study aimed to investigate self-reported taste and smell dysfunction in individuals with diabetes and explore associations with clinical and behavioural factors.

Background: Early identification of pathological α-synuclein deposition (αSynD) may improve understanding of Lewy body disorder (LBD) progression and enable timely disease-modifying treatments.
Objectives: We investigated αSynD using a seed amplification assay and assessed prodromal LBD symptoms in individuals with idiopathic olfactory dysfunction (iOD).
Methods: In this cross-sectional, case-control study, we included iOD participants and normosmic healthy controls (HC) aged 55 to 75 years without diagnoses of dementia with Lewy bodies, Parkinson's disease (PD), or other major neurological disorders.

Olfactory training (OT), a structured exposure to odors, is commonly used by otorhinolaryngologists to treat olfactory dysfunction. However, OT has been shown to improve cognition of people with cognitive or olfactory impairments and slow the age-related cognitive decline. This study investigated whether OT could enhance cognitive functions in older adults with an intact sense of smell, compared to younger adults.

Background: The World Health Organization recommends at-home management of mild COVID-19. While our preliminary evaluation provided evidence for saline nasal irrigation (SNI) and gargling in COVID-19, an update and risk-benefit assessment for self-care in Omicron infection is warranted, from treatment and preparedness perspectives, as new SARS-CoV-2 variants continuously emerge, while symptoms overlap with those of common colds and other upper respiratory tract infections.
Methods: Systematic literature searches for preclinical and clinical studies involving Omicron infection and saline, bias assessment, and review of outcomes (benefits, risks).
