Nose-to-brain delivery of lithium via a sprayable in situ-forming hydrogel composed of chelating starch nanoparticles.
J Control Release

While bipolar disorder patients can benefit from lithium therapy, high levels of lithium in the serum can induce undesirable systemic side effects. Intranasal (IN) lithium delivery offers a potential solution to this challenge given its potential to facilitate improved lithium transport to brain when delivered to the olfactory mucosa. Herein, a sprayable, in situ forming nanoparticle network hydrogel (NNH) based on Schiff base interactions between chelator-functionalized oxidized starch nanoparticles (SNPs) and carboxymethyl chitosan (CMCh) is reported that can be deployed within the nasal cavity to release ultra-small penetrative SNPs over time.

(1) Background: The administration of a live attenuated influenza vaccine (LAIV) has emerged as a viable option for preventing pediatric infections. The LAIV vaccine is available in China based on efficacy results. However, LAIV immunogenicity in children aged 3-17 years old in China has not yet to be studied and reported broadly.

Currently, targeted biological therapy is an innovative and highly effective approach in the treatment of severe chronic rhinosinusitis with nasal polyps (CRSwNP) associated with T2 inflammation that is uncontrolled by standard treatment methods. The article presents the first experience of long-term observation of a patient who, one year after the start of targeted biological therapy with dupilumab, independently stopped the treatment due to complete relief of symptoms of CRSwNP, despite recommendations to continue therapy to maintain control. At the same time, one year after the refusal of biological therapy, the patient showed persistent clinical remission in relation to the symptoms of CRSwNP, confirmed by the results of videoendoscopic examination of the nasal cavity and computed tomography of the sinuses.

To study the epidemiological characteristics of chronic tonsillitis (ChT), the need for patients to undergo conservative and surgical treatment, and a comparative assessment of the effectiveness of conservative treatment of patients with chronic tonsillitis using Tonsilotren as monotherapy and in complex treatment. The study involved 999 otorhinolaryngologists from the outpatient network of 20 major Russian cities. The data of 74125 patients diagnosed with ChT were analyzed.
