Abstract

OBJECTIVE: To evaluate whether short-term adjunctive oxymetazoline hydrochloride nasal spray is associated with improved early nasal recovery after endoscopic transnasal transsphenoidal surgery for pituitary adenoma. METHODS: This single-center retrospective propensity score-matched cohort study included adults undergoing first-time endoscopic transnasal transsphenoidal surgery between January 2021 and December 2024. Patients receiving oxymetazoline hydrochloride 0.05% nasal spray plus routine saline irrigation were compared with those receiving saline irrigation alone. The primary outcome was longitudinal change in Nasal Obstruction Symptom Evaluation (NOSE) score from postoperative baseline to weeks 1, 2, and 4. Secondary outcomes included endoscopic nasal findings, nasal comfort, responder-defined NOSE improvement, and short-term safety outcomes. RESULTS: Among 860 eligible patients, 630 remained after 1:1 propensity score matching, with 315 patients in each group. Baseline covariates and postoperative pre-intervention nasal status were well balanced. Adjunctive oxymetazoline was associated with lower NOSE scores and modestly more favorable endoscopic findings and nasal comfort during early follow-up, although the absolute between-group differences were small and attenuated by week 4. Responder analyses based on ≥ 30% NOSE score reduction showed no statistically significant between-group differences. Major postoperative nasal complications were comparable between groups. Potentially drug-related adverse reactions occurred in 55 patients in the oxymetazoline group (17.5%), mainly mild local symptoms, and no serious drug-related adverse events or treatment discontinuations were documented. CONCLUSIONS: Short-term adjunctive oxymetazoline combined with routine saline irrigation was associated with modest early nasal recovery benefits after endoscopic transnasal transsphenoidal surgery. Its use should remain cautious, selective, and time-limited, pending prospective confirmation of clinical benefit and long-term safety.

Role of omentin-1 in the global proteome of porcine pituitary cells: insights into proliferation- and apoptosis-related processes.

The anterior pituitary integrates endocrine regulation, cellular growth, and adaptive responses. Adipokines, secreted mainly by adipose tissue, act as hormonal signals linking metabolism, inflammation, appetite, and reproduction. They regulate hypothalamic-pituitary-ovarian axis by modulating hormone secretion and intracellular signaling. The presence of adipokine receptors in anterior pituitary suggests local metabolic-endocrine interactions. Omentin-1, predominantly expressed in visceral adipose tissue, participates in glucose metabolism and ovarian steroid regulation. Recent findings indicate that omentin-1 modulates tropic hormones, their receptors, and adipokine balance in anterior pituitary cells. We hypothesized that omentin-1 affects protein expression and signaling pathways involved in pituitary cell proliferation and apoptosis. This study examined its effects in anterior pituitary cells from Large White and Meishan pigs. Proteomic analysis identified 230 candidate differentially abundant proteins after omentin-1 treatment: 30 downregulated and 3 upregulated in Large White pigs, and 107 downregulated and 90 upregulated in Meishan pigs, associated with enriched 116 Gene Ontology terms. Key proteins were associated with cell cycle, DNA replication, gene expression, and posttranscriptional/posttranslational regulation. Responses differed between breeds. CDK5RAP2 and SIX1 were linked to proliferative control in Large White pigs, whereas AKT1S1 and RHOA were among the proteins associated with the broader proteomic response observed in Meishan pigs. Meishan pigs showed dynamic apoptotic protein regulation, including HTRA2, PARP2, and DFFA. Complementary in vitro experiments demonstrated that omentin-1 downregulated cyclins and caspase-3, upregulated BCL2, increased BCL2/BAX ratio, and modulated ERK1/2, AKT, AMPKα, and STAT3 phosphorylation. Together, these findings suggest that omentin-1 modulates proteomic networks and intracellular signaling associated with anterior pituitary cell function during the mid-luteal phase of the estrous cycle.

Glucocorticoid receptor antagonism in major depressive disorder with childhood trauma: a randomized controlled trial.

Childhood trauma (CT) is a key risk factor for major depressive disorder (MDD) onset and persistence. Hypothalamic-pituitary-adrenal (HPA) axis dysregulation may underlie this link, and preclinical studies suggest glucocorticoid receptor (GR) antagonism can reverse early life stress effects. This study tested whether the GR antagonist mifepristone reduces depressive symptoms in adults with MDD and CT. The RESET-medication study was a randomized, double-blind, placebo-controlled trial evaluating a 7-day course of mifepristone (1200 mg/day) or placebo in 158 adults with MDD and CT, assessed at baseline, 1 week, 6 weeks (primary endpoint), 3 months, and 6 months. The primary outcome was depressive symptom severity (IDS-SR) at week 6; secondary outcomes included symptom severity at other timepoints, clinical response, remission, anxiety, sleep, stress, disability, and salivary cortisol. At week 6, depressive symptoms declined in both groups, with no significant difference between mifepristone and placebo (b=-0.25, d=-0.03, 95% CI [-0.42, 0.36], pnom=0.887), and no group differences were found for secondary outcomes. Morning and evening cortisol were significantly higher with mifepristone at week 1, consistent with GR antagonism, but not at week 6. Adverse events were more frequent with mifepristone; mild and severe events occurred significantly more often, while the proportion reporting at least one adverse event was numerically higher but not statistically significant (93.6%vs. 82.5%, χ²(1)=3.60, p=0.058). Mifepristone produced the expected endocrine response but did not lead to clinical improvements in individuals with MDD and CT compared to placebo.

Clinical and genetic features of Ph-negative myeloproliferative neoplasms with dual-driver gene positivity.

OBJECTIVES: To investigate the clinical laboratory characteristics and gene mutation features of dual-driver gene positivity in patients with Philadelphia chromosome-negative myeloproliferative neoplasm (Ph-negative MPN). METHODS: We conducted a retrospective analysis of clinical data and genetic test results from 203 newly diagnosed patients with Ph-negative MPN. Of these, 194 had single-driver gene positivity and 9 had dual-driver gene positivity. High-throughput sequencing was used to detect mutations in JAK2, CALR, and MPL. Clinical characteristics and gene mutation profiles were compared between the two patient groups. RESULTS: The incidence of dual-driver gene positivity was 4.4% (9/203), with the most common combinations being JAK2 with CALR (4 patients) and JAK2 with MPL (4 patients). Compared with the single-driver group, the dual-driver group had a significantly higher risk of bleeding [4.1% (8/194) vs. 33.3% (3/9), P = 0.008] and a higher proportion of uncommon mutations [3.6% (7/194) vs. 33.3% (3/9), P = 0.006]. No statistically significant differences were observed between the two groups regarding age, thrombosis incidence, splenomegaly, or routine blood test indicators. During follow-up, 1 patient in the dual-driver group died from cerebrovascular disease. No leukaemia transformation or disease-related deaths occurred among the remaining patients. DISCUSSION: The increased bleeding risk in dual-driver patients may be related to a higher proportion of CALR mutations, elevated platelet counts, and higher variant allele frequencies, though these findings require validation in larger cohorts due to the small sample size. The higher prevalence of uncommon mutations suggests a more complex mutational landscape in this subgroup. CONCLUSION: Patients with Ph-negative MPN and dual-driver gene positivity may have a higher risk of bleeding and a more complex gene mutation profile.
