Purpose: This study examined the status of arthroscopic shoulder surgery in ambulatory settings by analyzing a single institutional database. Materials and Methods: Three hundred and eight arthroscopic shoulder surgeries performed between June 2022 and March 2023 were reviewed retrospectively. Propensity score matching (1-to-2) was performed between the day surgery group and the inpatient group according to sex, age, tear size, and interscalene nerve block (ISNB). Finally, 59 patients in the day surgery group and 118 patients in the inpatient group were matched. The indications of the day surgery were pre-determined according to the American Society of Anesthesiologists classification I or II, and the patient's social, medical, and surgical factors were thoroughly analyzed to define the target group of the day surgery. Complications related to voiding difficulty were prevented by classifying the patients using the International Prostate Symptom Score (IPSS) before surgery, and preventive medications were prescribed in the higher-risk patients with an IPSS of more than 7. To reduce postoperative pain, ISNB and patient-controlled analgesia (PCA) were applied to all patients during the study period, while day surgery patients received an additional bolus injection (5 cc of 0.375% ropivacaine+5 cc of normal saline) before discharge instead of continuous ISNB PCA. This study compared the postoperative pain assessments at discharge and on postoperative days 1, 2, and 14, as well as the total volume of saline irrigation, surgical time, and complications between the day surgery and inpatient groups. Results: The visual analogue scale for pain (pVAS) at the time of surgery were comparable in the day surgery group (4.1±1.5) and inpatient surgery group (4.1±1.1), with no significant difference between them (p=0.35). Similarly, the postoperative pVAS at 1, 2, and 14 days postoperatively was similar in the two groups (all p>0.05). The surgical-related factors, such as the total volume of saline irrigation and surgical time, were similar in the two groups. Furthermore, there was no significant difference in postoperative complications between the two groups (all p>0.05). Conclusion These results show that arthroscopic shoulder surgery in ambulatory settings is a safe alternative to inpatient surgery.

Background: The stimulatory effects of caffeine contribute to poor sleep quality. However, the relationship between caffeinated beverages and sleep quality, considering frequency or types of caffeinated beverages, were not extensively studied. Methods: Data were collected from 160 urban workers (75 men [46.9%] aged 20–69 years; with an average age of 41.8±12.3 years) using a structured, self-administered online questionnaire. Sleep quality, time, satisfaction; types and frequency of caffeinated beverages (number of cups per week; Q1: 0 cup, Q4: 14 or more cups per week), demographics, and health behaviors were asked. Sleep quality were evaluated using the Korean version of the Pittsburgh Sleep Quality Index (PSQI-K). Multiple regression analysis was conducted on the association between the frequency of caffeinated beverages consumption and sleep quality. Results: The most frequently consumed beverages were unsweetened coffee (22.8%) and the most common time for caffeine was between 12 pm to 5 pm (58.2%). The average sleep quality score based on the PSQI-K was 6.0±2.0 overall, 5.3±1.6 in Q1, and 6.6±2.2 in Q4 (frequent caffeinated beverage drinkers), indicating poorer sleep quality in Q4 (P=0.022). In Q1, 13.3% rated their sleep quality as ‘very good,’ while in Q4, only 2.5% gave the same rating. Poor sleep quality was significantly associated with the frequency of caffeinated beverages per week (β=0.232, P=0.004) and self-reported stress level (β=0.256, P=0.002). Conclusions Frequent consumption of caffeinated beverages appears to be associated with poor sleep quality among urban workers. While reducing caffeine intake may contribute to improvements in sleep quality as a health promoting behavior, this hypothesis requires validation through future studies employing personalized intervention approaches.

An herbal medicinal product consisting of three kinds of herbal materials, Prunella vulgaris L. (Lamiaceae), Clematis chinensis Osbeck (Ranunculaceae) and Trichosanthes kirilowii Max. (Cucurbitaceae) has been prescribed in the clinic for treating rheumatoid arthritis in Korea. In the present study, we investigated the antidepressive effect of this herbal complex extract (HCE) on lipopolysaccharide (LPS)-induced depression-like behavior. The effects of HCE on LPSinduced depressive-like behaviors were evaluated using a forced swimming test (FST) and splash test. In addition, we also evaluated locomotor activity and anxiety-like behaviors using the open field test and elevated plus-maze (EPM) test.Inflammatory cytokines were evaluated in the cortical regions. HCE attenuated anxiety-like behavior in the EPM test and depressive- and anhedonia-like behaviors induced by LPS in the FST and splash test. In addition, LPS-induced increases in the phosphorylation levels of protein kinase B (Akt) and glycogen synthase kinase 3 beta (GSK-3β) and expression levels of proinflammatory factors in the cortex were normalized by HCE. Moreover, decreases in the level of BDNF in the cortex were attenuated by HCE. These results suggest that HCE attenuates inflammation-induced depression-like behaviors through its normalization of Akt-GSK-3β signaling and proinflammatory factors and its upregulation of BDNF in the cortex and that HCE has therapeutic potential for depressive disorders in inflammatory states.

Purpose: Enhanced recovery after surgery (ERAS) protocols advocate reduced fasting and early nutrition to improve recovery in surgical patients. However, data on ERAS implementation among Korean surgeons performing major abdominal surgeries remain sparse. Methods: A survey conducted by the External Relation Committee of the Korean Society of Surgical Metabolism and Nutrition assessed perioperative nutritional practices among 389 Korean general surgeons from February to September 2023. The survey covered preoperative fasting, carbohydrate drinks, nasogastric tube use, postoperative dietary progression, parenteral nutrition (PN), and oral supplements, yielding 551 responses stratified by specialty. Results: More than 80% of respondents practiced “midnight NPO (Nil Per Os)” fasting, often at the anesthesiology department’s request, while 70%–80% reported no use of preoperative carbohydrate drinks. Most surgeons began dietary progression with water on postoperative day one, advancing to a liquid or soft diet by day two. PN was routinely prescribed by 49% of respondents, with a common dosage of 1,000–1,500 kcal/d. Oral supplements were selectively provided, with 21% of surgeons prescribing them universally. Conclusion The results reveal significant variability in perioperative nutrition practices across Korean surgical specialties, with many adhering to traditional practices despite ERAS guidelines. These findings highlight a need for standardized guidelines in Korea to optimize perioperative nutritional support and improve patient recovery outcomes following major abdominal surgeries.
