It can be a manifestation of various underlying psychiatric or medical conditions, such as schizophrenia, mood disorders, or neurological disorders. When conventional treatments fail to alleviate symptoms, ketamine, a dissociative anesthetic, has emerged as a potential therapeutic option for catatonia.

The aim of this study was to assess the efficacy and safety of mirikizumab compared with other biologic drugs approved for the treatment of moderately to severely active UC. This systematic review with frequentist network meta-analysis (NMA) included randomized controlled trials (RCTs) that evaluated the use of adalimumab, golimumab, infliximab, mirikizumab, vedolizumab, and ustekinumab compared with placebo or with another approved biologic drug. The NMA was conducted using the netmeta R software package. The P score was used to determine the treatment ranking. A total of 14 RCTs were included in the analysis. No significant differences were observed in the incidence of clinical response and remission between mirikizumab and other drugs. Mirikizumab was superior to placebo for clinical response (induction: odds ratio [OR] = 2.38; 95% confidence interval [CI]: 1.63-3.48; maintenance: OR = 3.31, 95% CI: 1.59-6.89) and remission (induction: OR = 2.09, 95% CI: 1.20-3.63; maintenance: OR = 2.96; 95% CI: 1.62-5.40). The probability plot indicated that infliximab might be the most effective option in terms of both clinical response and remission (P score, 0.8971 and 0.8814, respectively) in induction phase. No significant differences were noted between the studied drugs in any adverse events (AEs), serious AEs (SAEs) and infections for the induction phase, and in any AEs, infections and serious infections for the maintenance phase. The drugs differed in terms of discontinuation due to AEs (induction and maintenance phases) as well as SAEs and serious infections (maintenance phase). Mirikizumab did not differ from other biologics in terms of clinical response and remission for both induction and maintenance phases in patients with UC. Mirikizumab during the induction phases achieved rank 3 for clinical response and rank 5 for clinical remission. Therefore, it represents a valuable treatment option. The lack of significant differences in the risk of AEs and SAEs suggests that mirikizumab has a similar safety profile to the other drugs.</p>","PeriodicalId":20013,"journal":{"name":"Pharmacotherapy","volume":" ","pages":"811-821"},"PeriodicalIF":2.9,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142351910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the association between delirium and the subsequent monthly use of anticholinergic, sedative, and opioid medications in the 1 year after delirium in older adults with AD.MethodsThis comparative interrupted time series analysis involved adults (aged 65 years and older) with a diagnosis of AD initiating on cholinesterase inhibitors (ChEIs) based on 2013–2017 Medicare data. Separate patient‐level segmented regression models were used for each outcome to evaluate changes in the cumulative anticholinergic burden (CAB), sedative load, and opioid load after the delirium/index event using a 12‐month baseline and follow‐up period among patients who had a delirium event and those without delirium (control group). Propensity score‐based stabilized weights were utilized to balance baseline factors in the delirium and control groups.ResultsThe study included 80,019 older adults with AD with incident ChEI use; 17.11% had delirium. There was an immediate decline in monthly CAB after the delirium event (mean estimate −0.86, <jats:italic>p</jats:italic>‐value: 0.01) compared to the control group. A similar decline was observed when examining the sedative load (−0.06, <jats:italic>p</jats:italic>‐value: 0.002) after the delirium event. However, there was no decline in opioid load (−0.50, <jats:italic>p</jats:italic>‐value: 0.18).

Traditional management strategies, including dietary, exercise, and behavioral interventions, often result in insufficient and unsustainable weight loss. Lifestyle modification remains the cornerstone of obesity management, providing the foundation for other strategies. While options such as bariatric surgery remain an effective intervention for severe obesity, it is associated with its own set of risks and is typically reserved for patients who have not achieved the desired results with pharmacotherapy and lifestyle interventions. Incretin hormone agonists represent a significant advancement in the pharmacotherapy of obesity, offering substantial weight reduction and cardiometabolic benefits. Agents like liraglutide, semaglutide, and tirzepatide supported by key clinical trials such as Satiety and Clinical Adipose Liraglutide Evidence (SCALE), Semaglutide Treatment Effect in People with Obesity (STEP) program trials, and Tirzepatide Once Weekly for the Treatment of Obesity (SURMOUNT-1) have demonstrated remarkable efficacy in promoting weight loss and improving metabolic outcomes. Additionally, novel therapies, including dual and triple incretin agonists, are under investigation and hold the potential for further advancements in obesity treatment. These novel therapies can be categorized by their mechanisms of action and route of administration into oral glucagon-like peptide-1 (GLP-1) receptor agonists, triple agonists (targeting GLP-1, glucose-dependent insulinotropic polypeptide [GIP], and glucagon receptors), and glucagon receptor-GLP-1 receptor co-agonists. Other innovative approaches include oral GIP-GLP-1 receptor co-agonists, and the combination of long-acting amylin receptor agonists with GLP-1 receptor agonists. The ongoing development of incretin-based therapies and the expanding availability of currently available agents are expected to enhance clinical outcomes further and reduce the burden of obesity-related health complications.
