Objective: To determine the efficacy of posterior nasal nerve (PNN) cryoablation for improving the symptoms of chronic rhinitis.
Study Design: Retrospective cohort study.
Setting: A private practice.
Methods: This study evaluated medication usage and adverse effects of in-office PNN cryoablation with a handheld device in patients > 18 years with chronic (>6 months) allergic or nonallergic rhinitis for whom medical management failed. The total nasal symptom score (TNSS) and mini rhinoconjunctivitis quality of life questionnaire (mRQLQ) scores were compared before and after treatment.
Results: This study included 127 patients with a mean age of 52.4 ± 16.9 years; 60.6% of patients were female and 49.6% had allergic rhinitis. Mean symptom scores decreased from 5.94 (95% confidence interval [CI], 5.51-6.43) to 3.44 (95% CI, 2.97-3.81, < .001) after the procedure, with clinically important decreases in 75 (59.1%) patients. For patients with baseline TNSS values of ≥4, 63.5% (66/104) had a clinically important decrease, whereas only 39.1% (9/23) of those with the lower baseline did ( = .04). Mean mRQLQ scores also decreased from 2.51 (95% CI, 2.29-2.72) to 1.28 (95% CI, 1.20-1.47, < .001) after the procedure. Seventy-eight of 273 (28.6%) medications were discontinued after the procedure. Adverse effects occurred in 18.1% (23/127) of patients with headache as the most common.
Conclusion: PNN cryoablation improves nasal symptoms and quality of life in patients with chronic rhinitis. Patients with a higher baseline TNSS are more likely to experience significant symptomatic improvement.

Type 2 diabetes mellitus (T2DM) represents a chronic metabolic disorder characterized by disrupted carbohydrate and lipid balance, resulting in hyperglycemia. This study evaluated the impact of polysaccharides derived from Cynanchum auriculatum Royle ex Wight (CRP) on mitigating hyperglycemia and modulating intestinal microbiota in T2DM mice. Findings indicated that CRP is mainly linked by →6)α-D-Glcp-(1→ and CRP-H demonstrated greater efficacy than CRP-L in regulating hypoglycemic-related indicators such as serum high-density lipoprotein cholesterol (HDL-c) level.

Neuropathic pain is a disorder affecting the somatosensory nervous system. However, this condition is also characterized by significant neuroinflammation, primarily involving CNS-resident non-neuronal cells. A promising target for developing new analgesics is histamine H receptor (HR); thus, we aimed to determine the influence of a novel HR antagonist/inverse agonist, E-98 (1-(7-(4-chlorophenoxy)heptyl)-3-methylpiperidine), on pain symptoms and glia activation in model of neuropathic pain in male mice (chronic constriction injury to the sciatic nerve).

Background: Opioid use disorder (OUD) continues to pose a significant challenge to public health in the United States. Chronic pain and OUD are highly comorbid conditions, yet few studies have examined the relative associations of pain status and severity toward multidimensional OUD recovery outcomes (e.g.

Background And Aims: Around 750,000 patients per year will be cured of HCV infection until 2030. Those with compensated advanced chronic liver disease remain at risk for hepatic decompensation and de novo HCC. Algorithms have been developed to stratify risk early after cure; however, data on long-term outcomes and the prognostic utility of these risk stratification algorithms at later time points are lacking.
