Background: Regdanvimab has decreased the time to clinical recovery from coronavirus disease 2019 (COVID-19) and lowered the rate of oxygen therapy according to the results from phase 2/3 randomized controlled trial. More information is needed about the effects and safety of regdanvimab. Methods: We analyzed data for patients with high-risk mild or moderate COVID-19 being admitted to Busan Medical Center between December 1, 2020 and April 16, 2021. A propensity score (PS) matched analysis was conducted to compare patients treated with and without regdanvimab. The primary outcome was in-hospital death or disease aggravation which means the need for oxygen therapy (low- or high-flow oxygen therapy and mechanical ventilation) and secondary outcomes comprised the length of hospital stay and adverse reactions. Results: Among 1,617 selected patients, 970 (60.0%) were indicated for regdanvimab. Of these, 377 (38.9%) were administered with regdanvimab. Among a 1:1 PS-matched cohort of 377 patients each treated with and without regdanvimab, 19 (5%) and 81 (21.5%) reached the composite outcome of death, or disease aggravation, respectively (absolute risk difference, −16.4%; 95% confidence interval [CI], −21.1, −11.7; relative risk difference, 76.5%; P < 0.001).Regdanvimab significantly reduced the composite outcome of death, or disease aggravation in univariate (odds ratio [OR], 0.194; 95% CI, 0.112–0.320; P < 0.001) and multivariableadjusted analyses (OR, 0.169; 95% CI, 0.095–0.289; P < 0.001). The hospital stay was shorter for the group with than without regdanvimab. Some hematological adverse reactions were more frequent in the group without regdanvimab, but other adverse reactions did not significantly differ between the groups. Conclusion Regdanvimab was associated with a significantly lower risk of disease aggravation without increasing adverse reactions.

Idiopathic scrotal calcinosis is a rare benign disease of scrotal skin, characterized by multiple asymptomatic nodules on the scrotum. The lesions are asymptomatic, round, firm, and yellowish nodules with variable size. Herein, we report a case of idiopathic scrotal calcinosis and a short review of the literature. A 42-year old man presented multiple painless, firm, nodules on his scrotum for about ten years. After excision of the nodules, mixture of calcified material was observed as a typical histological feature of idiopathic scrotal calcinosis.

The prognostic significance of the squamous cell carcinomas of the oral and oropharynx have been evaluated to identify those features associated with aggressive biologic behavior according to the immunologic and histologic characteristics. For determining prognostic indicators, the authors performed immunohistochemical staining of p53 and epidermal growth factor receptor(EGFR) in 29 cases of squamous cell carcinomas of the oral and oropharynx. The expression rate of p53 was 51.7%, that of EGFR was 96.6%, and overexpression rate of EGFR was 41.4%, however there were no statistical significance between the reactivity of EGFR, p53 and clinicopathological features such as primary stage, nodal stage, clinical stage, death and histologic grade.

Rhinorrhea in allergic rhinitis (AR) is characterized by the secretion of electrolytes in the nasal discharge. The secretion of Cl– and HCO3 – is mainly regulated by cystic fibrosis transmembrane conductance regulator (CFTR) or via the calciumactivated Cl– channel anoctamin-1 (ANO1) in nasal gland serous cells. Interleukin-4 (IL-4), which is crucial in the development of allergic inflammation, increases the expression and activity of ANO1 by stimulating histamine receptors. In this study, we investigated ANO1 as a potential therapeutic target for rhinorrhea in AR using an ANO1 inhibitor derived from a natural herb. Ethanolic extracts (30%) of Spirodela polyrhiza (SPEtOH) and its five major flavonoids constituents were prepared. To elucidate whether the activity of human ANO1 (hANO1) was modulated by SPEtOH and its chemical constituents, a patch clamp experiment was performed in hANO1-HEK293T cells. Luteolin, one of the major chemical constituents in SPEtOH, significantly inhibited hANO1 activity in hANO1-HEK293T cells. Further, SPEtOH and luteolin specifically inhibited the calcium-activated chloride current, but not CFTR current in human airway epithelial Calu-3 cells. Calu-3 cells were cultured to confluency on transwell inserts in the presence of IL-4 to measure the electrolyte transport by Ussing chamber. Luteolin also significantly inhibited the ATP-induced increase in electrolyte transport, which was increased in IL-4 sensitized Calu-3 cells. Our findings indicate that SPEtOH and luteolin may be suitable candidates for the prevention and treatment of allergic rhinitis. SPEtOH- and luteolin-mediated ANO1 regulation provides a basis for the development of novel approaches for the treatment of allergic rhinitis-induced rhinorrhea.

OBJECTIVE: To investigate the effects of full-time integrated self upper-extremity training program (FISUTP) on functional recovery and length of stay in stroke patients. METHOD: Fifty-nine patients were enrolled and divided into FISUTP and control groups. The FISUTP group (n=29) underwent conventional physical and occupational therapy and FISUTP daily during their hospital stay, whereas control group (n=30) received only daily conventional therapy (physical and occupational therapy). The outcome was measured by Korean version of modified Barthel index (K-MBI), Fugl-Meyer motor assessment (FMA), and length of stay (LOS). RESULTS: FISUTP group showed significantly shorter LOS and higher improvement in functional status changes (K-MBI changes and FMA changes) during hospital day than control group (p<0.05). CONCLUSION: The results showed FISUTP is an effective treatment for the improvement of functional outcome and reduction of hospital stay in stroke patients.

We report a rare case of an idiopathic pseudoaneurysm causing intraventricular hemorrhage (IVH). A 28-year-old man presented with sudden onset of severe headache. He underwent external ventricular drainage for an isolated IVH in the right lateral ventricle. Digital subtraction angiography (DSA) revealed that the aneurysm (7.5x4.5 mm) arose from the distal part of the medial lenticulostriate artery. Following removal of the external ventricular drainage catheter, the aneurysm decreased in size (4.0x2.3 mm). However, follow-up DSA revealed a slightly enlarged aneurysm (4.2x3.2 mm) with morphologic change. The aneurysm was clipped via the interhemispheric transcallosal approach, but postoperative DSA revealed a residual aneurysm sac beside the clips. Given the risk of rebleeding, a second operation was planned for complete resection of the aneurysm. After revised craniotomy and careful dissection of the caudate nucleus, the aneurysm sac was completely resected. Histopathological examination revealed that the aneurysm was a pseudoaneurysm. The patient recovered without any neurological sequel and was discharged. To the best of our knowledge, this is the first reported case of an idiopathic lenticulostriate artery pseudoaneurysm protruding into the right lateral ventricle and causing an IVH that was successfully treated with microsurgical resection.

This study analyzed the seeds of Zizyphus jujuba var. inermis commonly used as a remedy in traditional Chinese medicine, in order to determine its various biologically active compounds. Through process 3-pentadecylcatechol, ρ-menth-8-ene, and γ-bisabolene were isolated and identified for the first time which are urushiol, monoterpenoidal, and sesquiterpenoidal compounds, respectively. Also, found were another sesquiterpenoidal compounds, vomifoliol, and four steroidal compounds, β-sitosterol, stigmasterol, stigmasta-5,23-dien-3β-ol, and stigmast-4-en-3-one. In addition, fourteen triterpenoidal compounds were isolated and identified. These were lupeol, betulinic acid, betulinaldehyde, alphitolic acid, 3-O-cis-ρ-coumaroyl-alphitolic acid, 3-O-trans-ρ-coumaroylalphitolic acid, 2-O-cis-ρ-coumaroyl-alphitolic acid, 2-O-trans-ρ-coumaroyl-alphitolic acid, zizyberanalic acid, ceanothic acid, oleanolic acid, maslinic acid, 3-O-cis-ρ-coumaroyl-maslinic acid, and 3-O-trans-ρ-coumaroylmaslinic acid. The structures were identified by comparing of the spectroscopic experiments, NMR and MS, and then compared that reported data, respectively. Three extracts of water, methanol, and chloroform from the seeds showed a weak anti-proliferative effect, anti-microbial activity, and anti-oxidant effect, respectively.
