Purpose: To compare short-term efficacy and safety of intravitreal brolucizumab injection with aflibercept in treatment-naive neovascular age-related macular degeneration (nAMD) patients. Methods: A total of 59 eyes from 59 treatment-naive nAMD patients in three hospitals were retrospectively reviewed. Of which, 27 patients underwent intravitreal brolucizumab injections and 32 received aflibercept. After monthly consecutive three injections, best-corrected visual acuity (BCVA; in logarithm of minimal angle of resolution [logMAR]), central macular thickness (CMT), dry macula achievement rate, and intraocular inflammation (IOI) incidence were compared. Results: After loading-phase treatment, BCVA was significantly increased from 0.48 ± 0.30 logMAR at baseline to 0.33 ± 0.21 logMAR at 3 months in the brolucizumab group (p = 0.002) and 0.40 ± 0.39 logMAR at baseline to 0.33 ± 0.36 logMAR at 3 months in the aflibercept group (p = 0.007). But there was no significant difference in BCVA improvement at 3 months between the two groups. CMT significantly decreased from 429.67 ± 250.59 μm at baseline to 210.67 ± 93.53 μm at 3 months in the brolucizumab group and from 346.69 ± 159.09 μm to 234.52 ± 83.42 μm in the aflibercept group (both p < 0.001). The amount of CMT reduction was significantly greater in the brolucizumab group after 3 months (p = 0.036). In typical AMD eyes, brolucizumab showed similar BCVA improvement but better CMT reduction at 3 months (p = 0.018). Dry macula achievement rate was not significantly different between the two groups. One IOI was observed in the brolucizumab group. Conclusions Intravitreal injections of brolucizumab and aflibercept showed similar anatomical and functional outcomes. But CMT reduction was greater in the brolucizumab group. One IOI was identified, which was tolerable for topical agents. These results suggest that brolucizumab could be a novel first line treatment option for treating naive nAMD patients.

This report provides a detailed description of the methodology for ophthalmic examinations according to the Korea National Health and Nutrition Examination Survey (KNHANES) VII and VIII (from 2017 to 2021). The KNHANES is a nationwide survey which has been performed since 1998 in representatives of whole Korean population. During the KNHANES VII and VIII, in addition to the ophthalmic questionnaire, intraocular pressure measurement, visual field test, auto refractometry, axial length and optical coherence tomography measurements were included. This new survey will provide not only provide normative and pathologic ophthalmic data including intraocular pressure, refractive error, axial length, visual field and precise measurement of anterior segment, macula and optic nerve with optical coherence tomography, but also a more accurate diagnosis for major adult blindness diseases, including age-related macular degeneration, diabetic retinopathy, glaucoma, and other ocular diseases, for the national Korean population.

Fibromuscular dysplasia is a nonatheromatous, noninflammatory arterial disorder that results in stenosis and/or aneurysm formation and rarely involves the mesenteric arteries. Herein, we report a case of fibromuscular dysplasia limited to the inferior mesenteric artery, which manifested with arterial aneurysms and ischemic colitis.

Serous cystic neoplasms of the pancreas are usually benign, with a low malignant potential. Herein, we report a case of malignant serous cystic neoplasm of the pancreas treated with subtotal pancreatectomy, which progressed to local recurrence and metachronous hepatic metastasis during the regular follow-up period.

OBJECTIVE: Inflammation is crucial to limiting vascular disease. Previously we reported that acrolein, a known toxin in tobacco smoke, might play an important role in the progression of atherosclerosis via an inflammatory response involving cyclooxygenase-2 (COX-2) and prostaglandin production in human umbilical vein endothelial cells (HUVECs). Curcumin has been known to improve vascular function and have anti-inflammatory properties. In this study, we investigated whether curcumin prevents the induction of inflammatory response caused by acrolein. METHODS: Anti-inflammatory effects of curcumin were examined in acrolein-stimulated HUVECs. Induction of proteins, mRNA, prostaglandin and reactive oxygen species (ROS) were measured using immunoblot analysis, real-time reverse-transcription polymerase chain reaction, enzyme-linked immunosorbent assay and flow cytometry, respectively. RESULTS: Curcumin attenuates inflammatory response via inhibition of COX-2 expression and prostaglandin production in acrolein-induced human endothelial cells. This inhibition by curcumin results in the abolition of phosphorylation of protein kinase C, p38 mitogen-activated protein kinase, and cAMP response element-binding protein. Furthermore, curcumin suppresses the production of ROS and endoplasmic reticulum stress via phosphorylation of eukaryotic initiation factor-2α caused by acrolein. CONCLUSION These results suggest that curcumin might be a useful agent against endothelial dysfunction caused by acrolein-induced inflammatory response.

Nausea and emesis are a major side effect and obstacle for chemotherapy in cancer patients. Employ of antiemetic drugs help to suppress chemotherapy-induced emesis in some patients but not all patients. Ginger, an herbal medicine, has been traditionally used to treat various kinds of diseases including gastrointestinal symptoms. Ginger is effective in alleviating nausea and emesis, particularly, for cytotoxic chemotherapy drug-induced emesis. Ginger-mediated antiemetic effect has been attributed to its pungent constituents-mediated inhibition of serotonin (5-HT) receptor activity but its cellular mechanism of action is still unclear. Emetogenic chemotherapy drugs increase 5-HT concentration and activate visceral vagal afferent nerve activity. Thus, 5-HT mediated vagal afferent activation is essential to provoke emesis during chemotherapy. In this experiment, water extract of ginger and its three major pungent constituent's effect on 5-HT-evoked responses were tested on acutely dispersed visceral afferent neurons with patch-clamp methods. The ginger extract has similar effects to antiemetic drug ondansetron by blocking 5-HT-evoked responses. Pungent constituents of the ginger, [6]-shogaol, [6]-gingerol, and zingerone inhibited 5-HT responses in a dose dependent manner. The order of inhibitory potency for these compounds were [6]-shogaol>[6]-gingerol>zingerone. Unlike well-known competitive 5-HT3 receptor antagonist ondansetron, all tested ginger constituents acted as non-competitive antagonist. Our results imply that ginger and its pungent constituents exert antiemetic effects by blocking 5-HT-induced emetic signal transmission in vagal afferent neurons.

PURPOSE: To evaluate clinical patterns according to the occlusion site in patients with branch retinal vein occlusion. METHODS: Ninety-one branch retinal vein occlusion patients were divided into 4 groups according to the occlusion site based on the description by Duke-Elder and Wybar: Papillary retinal vein occlusion group (group A), main retinal vein occlusion group (group B), minor retinal vein occlusion group (group C), and retinal venule occlusion group (group D). The following factors were analyzed retrospectively: baseline/final visual acuity, visual improvement, macular thickness, and macular circulatory states. RESULTS: The macular thickness (microm) was 575.33 +/- 178.44 in group A, 511.92 +/- 218.02 in group B, 397.21 +/- 144.51 in group C, and 336.68 +/- 120.55 in group D. The retinal ischemic area (DD) was 22.00 +/- 13.28 in group A, 18.26 +/- 10.12 in group B, 12.52 +/- 10.52 in group C, and 12.36 +/- 11.92 in group D, which was found to be significantly greater in the group with the higher branch occlusion site (p < 0.05). However, visual acuity, macular circulatory states and other clinical characteristics were not significantly different. CONCLUSIONS: Occlusion site is a relating factor for retinal ischemic area and macular thickness in patients with Branch retinal vein occlussion, but which is not a prognostic factor for final visual acuity.

Here, we report the poisoning case of 10 cows. Several distinct clinical signs such as convulsion, excessive salivation, circling, lateral recumbency, and death were observed. Necropsy and histopathological examination did not reveal any significant abnormal findings. Moreover, no bacteria or viruses were detected in tissue, blood, and feeding food. However, endosulfan was detected from the stomach contents and microbials. Our results strongly suggest that death of cows may be closely associated with endosulfan poisoning.
