Background: University students have been known as having a higher rate of problem drinking than the general population in South Korea. In particular, the university freshmen may experience problem drinking from increased occasions of frequent social gatherings at the first school year as they have increased time to freely use compared to the high school days. Problem drinking among university freshmen may be influenced by multiple factors. The present study aimed to examine the prevalence of problem drinking and to identify individualand family-level factors associated with university freshmen's problem drinking. Methods: A cross-sectional, correlation study was conducted. Participants were 227 university freshmen (70 men and 157 women) under the parenting of mother and father from 10 universities in Seoul. The problem drinking was evaluated by using the Alcohol Use Disorder Identification Test. Alcohol Abstinence Self-Efficacy Scale and Parental Authority Questionnaire for parenting behaviors were used. Results: The prevalence of problem drinking was 58.6% among university freshmen. An individual-level factor of alcohol abstinence self-efficacy was significantly associated with the prevalence of problem drinking (odds ratio, 0.94; 95% confidence interval, 0.91-0.96) among university freshmen. However, any of family-level factors including types of parenting behaviors were not significantly associated with the prevalence of problem drinking. Conclusions Alcohol abstinence self-efficacy may be a strong protective factor against university freshmen's problem drinking. University-based alcohol abstinence programs should comprise of nursing strategies including the enhancement of abstinence self-efficacy at the first school year.

Purpose: We report the clinical features, diagnoses, and treatments of patients with neuro-ophthalmological diseases presenting to a tertiary referral center emergency room (ER) of South Korea. Methods: We retrospectively analyzed the medical records of 205 patients who visited the ER of the Asan Medical Center and then were referred to our neuro-ophthalmology department from May 2020 to April 2022. The initial diagnoses of ophthalmology residents were compared to the final diagnoses of neuro-ophthalmologists. We describe the symptoms, diagnoses, and treatments. Results: The median time from the onset of symptoms to the ER visit was 3 days; diplopia (49.1%) and vision loss/a visual field defect (38.9%) were the chief complaints. The most common causes of diplopia were isolated cranial nerve 4 (37.5%), 6 (22.9%), and 3 palsy (18.4%) and supranuclear palsy (9.2%). In patients with vision loss/visual field defect, the most common causes were optic (20.5%), ischemic (17.1%), and compressive (8.0%) optic neuropathies. For 121 cases (59.0%), multidisciplinary consultations with the departments of neurology, neurosurgery, and internal medicine were scheduled. After initial management in the ER, 38 diagnoses (18.5%) changed after evaluation by neuro-ophthalmologists. Conclusions Over half of all neuro-ophthalmology patients presenting to an ER required comprehensive interdisciplinary evaluation and over a third required inpatient treatment.

Objectives: There is limited knowledge regarding the impact of lifestyle changes on cardiovascular events and mortality among individuals with prehypertension or prediabetes. Methods: This was a serial retrospective cohort study utilizing data from the Korean National Health Insurance Service Health Screening Cohort. The primary outcome considered in the study was major adverse cardiovascular events (MACE). Results: A higher risk of MACE was found in men with prehypertension whose unhealthy lifestyle deteriorated (hazard ratio [HR], 1.13; 95% CI, 1.04–1.23; P=0.004), those who gained weight (HR, 1.15;95% CI, 1.03–1.28; P=0.010), and those who began smoking (HR, 1.34; 95% CI, 1.17–1.55; P<0.001).Conversely, a reduced risk of MACE was observed in men with prehypertension who improved their unhealthy lifestyle, quit smoking, reduced alcohol consumption, or increased the frequency of physical activity. In men with prediabetes, the risk of MACE was higher in those whose unhealthy lifestyle worsened (HR, 1.23; 95% CI, 1.12–1.35; P<0.001), those who gained weight (HR, 1.19; 95% CI, 1.06–1.33; P=0.003), those who started smoking (HR, 1.41; 95% CI, 1.22–1.64; P<0.001), and those who decreased their physical activity frequency (HR, 1.21; 95% CI, 1.09–1.35; P<0.001). Conclusion Preventive lifestyle changes reduce cardiovascular events and mortality, particularly in men at risk of developing hypertension or type 2 diabetes.

Purpose: We aimed to investigate the visual recovery time in patients with ethambutol-induced toxic optic neuropathy (EON) and identify the factors associated with the visual recovery time. Methods: In this retrospective cohort study, we reviewed the medical records of 35 eyes from 35 patients with EON. Visual recovery was defined as a gain of three or more lines from the nadir. Results: Patients were observed following discontinuation of ethambutol (EMB), with the mean follow-up period of 21.0 ± 16.0 months. The visual acuity at nadir was logarithm of the minimum angle of resolution 1.4 ± 0.4, and the final visual acuity was logarithm of the minimum angle of resolution 0.6 ± 0.5. Twenty-seven eyes (77.1%) showed significant visual recovery. In Kaplan-Meier survival, the mean estimated time for visual recovery was 15.2 ± 3.0 months, and 50% of the patients experienced visual recovery at 8.3 ± 2.2 months following EMB discontinuation. Multivariate Cox regression analysis identified several significant risk factors for delayed visual recovery, including duration of EMB medication ≤6 months, period from symptom onset to EMB discontinuation >14 days, and baseline peripapillary retinal nerve fiber layer thickness >98 μm. Conclusions Our study indicated a mean time of visual recovery of 15 months for EON cases. Therefore, patients diagnosed with EON should be followed up for more than 1 to 2 years to evaluate their visual recovery. Delayed EMB discontinuation, short duration of EMB use, and initial peripapillary retinal nerve fiber layer thickening were associated with delayed visual recovery. Therefore, patients taking EMB should be followed up regularly for early detection of EON and immediate discontinuation of EMB to prevent severe damage to the optic nerve.

PURPOSE: To evaluate the clinical characteristics of intraorbital foreign bodies as well as the treatment outcomes. METHODS: This was a noncomparative interventional case series. Clinical data and radiographic images were gathered via retrospective chart reviews of 14 patients who underwent surgical removal of intraorbital foreign bodies by an oculoplastic surgeon at the Asan Medical Center, Seoul, Korea between July 2012 and November 2015. RESULTS: The mean age of patients was 45.1 years and 13 patients (92.9%) were male. There were 9 metallic; 3 nonmetallic, inorganic; and 2 organic intraorbital foreign bodies in this series. The most common orbital complication was orbital wall fracture (8, 57.1%), and one patient had orbital cellulitis associated with a wooden foreign body. Six patients (42.9%) underwent surgical removal of foreign bodies in a delayed setting, and 4 of them needed surgery to allow for the brain magnetic resonance image tests to evaluate neurologic problems. There were 6 patients (42.9%) who had a postoperative corrected visual acuity worse than 20/200, and all of them had poor visual acuity at the time of injury due to associated eyeball or optic nerve injuries. Four patients (28.6%) had eyeball movement limitations from the initial trauma, but only 1 patient had persistent limitations postoperatively. There were no other complications associated with surgical removal. CONCLUSIONS: The majority of patients with intraorbital foreign bodies were male who had periorbital traumas. The most common foreign body was metal, and orbital wall fractures were common. The poor visual prognosis was related to the eyeball or optic nerve injuries from the initial trauma. The urgent surgical removal should be performed for organic foreign bodies or associated orbital/ocular injuries. Metallic foreign bodies may also be considered for removal to allow for possible brain magnetic resonance image evaluations in the future.
