Abstract Changes in the clinical symptoms of acute graft-versus-host disease (GVHD) are currently used to assess treatment responses. The Mount Sinai Acute GVHD International Consortium (MAGIC) consortium has recently revealed that the integration of serum biomarkers with clinical symptoms at the onset of treatment in a MAGIC composite score (MCS) more accurately predicts treatment response and 6-month nonrelapse mortality (NRM) than clinical symptoms alone. In this study, we evaluated whether the integration of serum biomarkers and clinical symptoms on day 28 (D28) would also better predict NRM than clinical response only (CRO). We analyzed data from 1135 patients receiving systemic treatment for acute GVHD and created a fourth MCS category for patients with complete resolution of symptoms and low-risk clinical biomarkers on D28. Using a classification and regression tree model with 6-month NRM as the end point, we identified status of MCS 0 or MCS 1 at D28 as responses, which we termed the MAGIC composite response (MCR). In the validation cohort (n = 309), MCR more accurately predicted 6-month NRM than CRO (area under the curve: 0.77 vs 0.69; P = .014) and demonstrated higher negative and positive predictive values. MCR correctly reclassified both clinical nonresponders and responders: 28 of 213 clinical responders (13%) became nonresponders with fivefold higher NRM (34.3% vs 6.8%, P < .001) and a larger group (29/96, 30%) of clinical nonresponders became responders with sixfold lower NRM (7.6% vs 50.7%, P < .001). These findings support the use of MCR as a superior surrogate end point for long-term GVHD control and survival in future clinical trials.

ABSTRACT Objective To derive precise estimates of anxiety and depressive disorder prevalence in patients with common vestibular disorders. Data Sources CINAHL, Cochrane Library, PubMed, PsycINFO, and SCOPUS. Review Methods This systematic review and meta‐analysis was reported per PRISMA guidelines. Outcomes included continuous measures (mean), proportions (%), and relative risks (RR) with 95% confidence intervals. Results Eighty‐five studies ( n = 764,403) examining anxiety, depression, and vestibular disorders in adults were included. Mean ages were 50.3 (vestibular) and 46.7 (control); females comprised 63.8% and 64.3%, respectively. Patients with vestibular disorders had significantly higher rates and risks of anxiety (31.4% vs. 8.3%, p < 0.0001; RR = 1.50, 95% CI: 1.1–2.0) and depression (28.3% vs. 4.7%, p < 0.0001; RR = 2.9, 95% CI: 1.8–4.4) than controls. Elevated rates were observed in benign paroxysmal positional vertigo (30.6%, 23.6%), Meniere's disease (47.0%, 43.1%), vestibular migraine (46.5%, 35.7%), and vestibular neuritis (19.4%, 20.7%) (all p < 0.0001). Episodic disorders showed higher prevalence than vestibular neuritis. Patients with unspecified peripheral vestibular disorders also had significantly higher anxiety (12.1%) and depression (13.2%) rates than controls. Meta‐regression revealed significant associations between Dizziness Handicap Inventory (DHI) scores and Hospital Anxiety and Depression Scale (HADS) anxiety and depression subscales. Conclusions This meta‐analysis offers the most precise prevalence and relative risk estimates of anxiety and depressive disorders in vestibular illness. The greater risk in episodic versus single‐event vestibular disorders may inform the understanding of vestibular–psychiatric comorbidity mechanisms.

BACKGROUND: Patients with functioning pituitary adenomas (FPA) require a multidisciplinary team-based approach to select best medical, surgical, and radiation treatments, including stereotactic radiosurgery (SRS). OBJECTIVE: The aim of this study was to provide evidence-based recommendations on the use of SRS for adult patients with FPA. METHODS: PubMed and Embase were searched from data base inception to June 8, 2021. Full-text articles were then screened using published exclusion/inclusion criteria. Evidence tables were developing based on data extraction from the full-text reviews, and evidence-based recommendations were finalized. RESULTS: Of the total 1842 abstracts pertinent to this topic, 343 full articles met eligibility. Of these, 21 met entry criteria and were included in the evidence tables. The provided Class III evidence supported 2 Level III recommendations: 1. SRS, hypofractionated SRS, fractionated (>5 fractions) radiotherapy, and conventional radiation therapy provide excellent radiographic control with variable hormonal reduction and endocrine remission rates. For SRS and fractionated radiotherapy hormonal reduction may continue for up to 10 years after treatment. 2. Clinicians may continue to administer endocrine suppressive medical treatment before SRS as this may not affect radiographic control. CONCLUSION: This systematic review provides evidence-based recommendations to guide providers caring for adult patients with FPA when making decisions pertinent to radiosurgery. The CNS Guidelines Committee will continue to pursue timely updates to further improve the care of patients with this diagnosis.

ABSTRACT Autosomal dominant polycystic kidney disease (ADPKD) is a genetic disease that is caused by mutations in PKD genes. Glucagon‐like peptide‐1 (GLP‐1) receptor agonists (GLP‐1RAs) are a class of medications that mimic the actions of the hormone GLP‐1, conferring beneficial effects on weight management and other metabolic conditions. However, whether GLP‐1RA plays a kidney‐protective action in ADPKD remains unknown. In this study, we define the role and mechanisms of one of the most popular GLP‐1RA agonists, Semaglutide, in ADPKD. We show that the expression of GLP‐1R is decreased in Pkd1 mutant renal epithelial cells and kidneys. Treatment with Semaglutide delays cyst growth in aggressive and long‐lasting Pkd1 mutant mouse models. Treatment with Semaglutide (1) decreases glucose uptake, ATP generation, and glycolysis, (2) deactivates PKD‐associated signaling pathways, including Rb, S6, and Stat3, resulting in a decrease in cell proliferation, (3) deactivates NF‐kB signaling pathways, resulting in a decrease in the expression of cytokines and the recruitment of macrophages, (4) normalizes mitochondrial morphology and function, (5) induces Pkd1 mutant renal epithelial cell death, (6) induces ketosis characterized by an increase in serum level of beta‐hydroxybutyrate (BHB) and the activation of AMPK, and (7) alleviates renal fibrosis through deactivation of TGF‐b signaling in Pkd1 mutant mouse kidneys. This study highlights the potential of GLP‐1R agonists as a novel therapeutic strategy for ADPKD treatment.

Background: Fat grafting is a common procedure in plastic and reconstructive surgery. It is associated with several disadvantages and complications, especially in patients undergoing recurrent procedures. Researchers are exploring the implications of cryopreserving adipose tissue and stem cells in plastic surgery. This article aimed to evaluate whether autologous fatty tissue and adipose-derived stem cells obtained through liposuction can be safely stored via cryopreservation for future surgical use. Methods: A comprehensive literature search was conducted across 3 databases, including PubMed, ScienceDirect, and Ovid MEDLINE, using specific keywords, yielding 75 articles. Studies that were not written in English or conducted in vitro were excluded. Only studies published in English within the last 5 years, and focusing on the use of cryopreservation of adipose tissue, were included. After review, a total of 22 articles met the inclusion criteria and were analyzed. Results: Cryopreserving adipose tissue and adipose-derived stem cells shows great potential in plastic surgery. Patient factors such as harvesting site, age, and obesity significantly impact the yield. The highest yield was obtained by harvesting from the abdomen and thigh. Additionally, cryopreservation requires cryoprotective agents, among which a combination of dimethyl sulfoxide and human serum albumin was most effective. Despite the advancement in cryoprotective agents, thawing adipose tissue results in cell death and impaired extracellular matrix integrity. However, cryopreserved stromal vascular fraction gel demonstrated fewer complications and better retention. Conclusions: The cryopreservation of adipose tissue and stromal vascular fraction gel demonstrates promising advancements for future applications in plastic surgery and regenerative medicine.
