Improvement of comorbid anxiety and depression in patients with migraine treated with injectable preventive calcitonin gene-related peptide antagonists: Review of clinical evidence.

Background: Migraine is often associated with depression and anxiety, leading to a diminished quality of life. Calcitonin gene-related peptide (CGRP) antagonists have shown promise in treating migraines, but their effects on concurrent depression and anxiety have not been clarified. Methods: A literature review was conducted on ClinicalTrials.gov, PubMed, Ovid Medline, and EMBASE focusing on phase 3 clinical trials, post-hoc analysis studies, and real-world evidence (RWE) published in the past 5 years. The review primarily utilized patient-reported outcome tools, such as the Patient Health Questionnaire-9, Hamilton Depression Rating Scale, Beck Depression Inventory-II, generalized anxiety disorder (GAD)-7, and Hamilton Anxiety Rating Scale (HARS), to assess anxiety and depression in relation to CGRP-targeted monoclonal antibodies. Results: Out of 260 studies, 17 met the inclusion criteria. Eptinezumab lacked sufficient evidence regarding its impact on depression and anxiety. While sufficient evidence on its effect on comorbid anxiety was not available, fremanezumab was shown to significantly improve comorbid depression in one study while not achieving statistical significance in another. Erenumab and galcanezumab showed significant improvement in comorbid depression, implying possible benefits in patients with migraine. Galcanezumab showed faster relief from depressive symptoms than other injectable CGRP antagonists. Galcanezumab also exhibited improvements in GAD-7 scores for anxiety, although not statistically significant, whereas RWE showed promising HARS scores for both galcanezumab and erenumab. Conclusions: Galcanezumab and erenumab appear to be more effective in improving concurrent depressive and anxiety symptoms in migraine patients than fremanezumab. Notably, these psychometric questionnaires were not the primary outcome measures of the trials and were not specifically designed to investigate the effects of these medications on depression or anxiety. Further research is needed to fully understand the impact of CGRP antagonists on mental health disorders associated with migraines. These findings have implications for enhancing the overall well-being and quality of life in individuals with migraines and comorbid psychiatric conditions.

Antibacterial Activity of Chitosan Nanoparticles Against Pathogenic N. gonorrhoea.

PURPOSE: The emergence of Neisseria gonorrhoeae strains that are resistant to the most commonly used antibiotics represents a great concern for global public health. This challenges the effectiveness of clinical treatment regimens and demands the development of alternative antigonococcal agent. In this regard, chitosan nanoparticles (CNPs) are known to have antimicrobial activity against a wide range of pathogens. Thus, they have become a potential candidate for combatting this era of multi-drug resistance. This study aims to formulate CNPs, characterize their physicochemical properties, and examine their antimicrobial activity against gonococcus. MATERIALS AND METHODS: The ionic gelation method was used to prepare CNPs of different concentrations. Characterization for their particle size (PZ), polydispersity index (PDI), and zeta potential (ZP) was performed. The anti-microbial activity of CNPs was investigated against 13 WHO N. gonorrhoeae reference strains, using the broth dilution method. Cytotoxicity of CNPs and their effect on bacterial adhesion to HeLa cells were investigated. RESULTS: The average PZ and ZP of the prepared NPs were increased when the concentration of chitosan was increased from 1 to 5 mg/mL and found to be in the range of 193 nm ± 1.9 to 530 nm ± 13.3, and 14 mV ± 0.5 to 20 mV ± 1, respectively. Transmission electron microscopes (TEM) images revealed spherical NPs, and the NPs had a low PDI value of ≤0.27. The formed CNPs produced antibacterial activity against all tested strains, including those resistant to multiple antibiotics, with a minimum inhibitory concentration (MIC90) of 0.16 to 0.31 mg/mL and a minimum bactericidal concentration (MBC) of 0.31 to 0.61 mg/mL. Of note, at all MIC90 and MBC, the CNPs had no significant cytotoxic effect on HeLa cells and reduced bacterial adhesion to these cells at MBC doses. CONCLUSION: The present work findings suggest the potential of the CNPs for the treatment of gonorrhoea.

Efficacy of scopolamine transdermal patch in children with sialorrhea in a pediatric tertiary care hospital.

BACKGROUND: Drooling is common in children with neurological disorders, but its management is very challenging, Scopolamine transdermal patch (STP) appears to be useful in controlling drooling, although it is not approved for this indication and there are limited clinical studies about its effectiveness. This study aimed (1) to assess the impact of STP use on the severity of drooling and on the frequency of emergency department (ED) and hospital readmission (RA) visits related to drooling, and (2) to determine the level of family satisfaction with STP when used in children with neurological disorders. METHODS: This is a retrospective cohort study of all pediatric patients aged 3-14 years, with non-progressive neurodevelopmental disability, who used STP for more than one year during the period between April 2015 and July 2018 (n = 44). Data on demographics, clinical status, comorbidities, STP dose and duration, other medications, ED and RA visits were collected. Follow-up phone-call interviews with parents/caregivers were performed using a parent-reported frequency and severity rating scale of sialorrhea. Absolute and relative risk reductions were calculated to assess the impact of STP on ED and RA visits. Significance was considered at p-value of ≤ 0.05. RESULTS: STP use showed significant reduction in severity of drooling (p < 0.001), wiping of the child's mouth (p < 0.001), bibs or clothing changes (p < 0.001), choking and aspiration of saliva (p = 0.001). The Relative Risk Reduction of the drooling-related ED and RA visits were 86% and 67% respectively. Nearly two-thirds (60%) of caregivers were satisfied with using STP. CONCLUSIONS: This is the first study of its kind done in Saudi Arabia demonstrating favorable impact of STP use by children on the consequences associated with drooling and with the frequency of ER and RA visits due to drooling. Development of a medication use protocol is recommended to standardize STP treatment in order to optimize its effectiveness. This study serves as baseline information for future prospective interventional studies.

Community needs and preferences for community pharmacy immunization services.

This study explored the Saudi community's needs and preferences related to community immunization services. Community member's expectations about the services were assessed, and their concerns, attitudes, and beliefs around the pharmacist's role in providing immunization were examined. METHOD: Qualitative in-depth, semi-structured interviews were conducted with a convenience sample that comprised Saudi community members who visited Saudi community pharmacies. Interviews were audio-recorded, transcribed verbatim, and then translated. Data obtained were then thematically organized and analyzed using NVivo (QSR International) Software. RESULT: A total of 20 interviews were conducted for this study. Seven themes emerged from the interviews and were grouped into three major categories relating to the community pharmacy immunization service: (1) community needs for the service; (2) community expectations of the service; and (3) community concerns, and beliefs around the service. Participants expressed their need for such services and acceptance of immunization performed by community pharmacists, with the expectation that it would improve their immunization uptake and community health in general. However, some participants expressed concerns about community pharmacists current level of ability and skill in providing immunization, the lack of a private area for conducting the service, the lack of female community pharmacists, and the cost of the immunization service. Some participants advocated for supervision of such services by the Ministry of Health (MOH) and Saudization of community pharmacy staff. CONCLUSION: The research results clearly demonstrated the Saudi community's need for community pharmacy immunization services, described their expectations, and highlighted their concerns relating to community pharmacy infrastructure and an appropriate level of training for community pharmacist-administered immunization.
