Purpose: Despite the widespread use of liquid skin adhesives (LSA), concerns persist regarding the increase in wound care costs. This study aimed to investigate the cost-effectiveness of LSA for surgical wound management. Methods: In this prospective, open-label, single-center randomized controlled trial, adults aged 19 years and older who were scheduled for elective minimally invasive colorectal surgeries were included. The participants were randomly divided into 2 groups: an n-butyl cyanoacrylate skin adhesive was used in the experimental group (LSA group), while a surgical skin stapler was employed in the control group (stapler group). The primary outcome measure was the sum of the total time required for wound management. Results: A total of 58 patients were randomly assigned to 2 groups, with 29 patients in each group. The findings revealed comparable wound complication rates in the 2 groups (8 out of 29 in the LSA group vs. 5 out of 29 in the stapler group, P = 0.530). Notably, the LSA group had a significantly shorter wound management time (median 235 seconds vs. 1,201 seconds, P < 0.001) and similar wound management cost (median US dollar [USD] 50.6 vs. USD 54.6, P = 0.529) compared to the stapler group. Subgroup analysis showed that the LSA group had a shorter management time for uncomplicated wounds and a lower cost for complicated wounds. Conclusion LSA not only provides a safe alternative but also offers a resource-efficient option for wound management compared to staplers.

Background: While Korea maintains a low prevalence of human immunodeficiency virus (HIV), the number of newly diagnosed cases has been steadily rising, reaching approximately 1,000 annually in recent years. The 2022 annual report from the Korea Disease Control and Prevention Agency revealed that women living with HIV (WLWH) constitute 6.4% of the total confirmed people living with the HIV population, totaling 1,219 individuals. Despite this, only a few studies have focused on WLWH in Korea. This study aims to analyze the epidemiological and clinical characteristics of WLWH in Korea. Materials and Methods: We retrospectively collected data by reviewing the medical records of all WLWH who visited 10 urban referral hospitals across Korea between January 2005 and May 2023. Results: A total of 443 WLWH were enrolled in this study. The predominant risk exposure was heterosexual contact, with 235 (53%) participants either married or cohabiting with a male partner at their initial clinic visit. Among the participants, 334 (77.7%) were Korean, 27 (6.1%) were Southeast Asian, and 19 (4.3%) were African. Antiretroviral therapy was initiated by 404 WLWH (91.2%). We observed 118 pregnancies in WLWH following their HIV diagnosis, resulting in 78 live births (66.1%), 18 induced abortions (15.2%), 10 pre-viable fetal losses (8.5%), and four stillbirths (3.4%). Over a cumulative follow-up duration of 3,202.1 years, the incidence rates of breast and cervical cancers were both 2.18 per 1,000 person-years. Additionally, the incidence rates of pelvic inflammatory disease, cervical intraepithelial neoplasm (above grade II), and osteoporosis were 4.67, 11.21, and 13.39 per 1,000 patient-years, respectively. Conclusion This is the first multicenter study to investigate the clinical and epidemiological characteristics of WLWH in Korea. The incidence and prevalence of diseases in women, including breast cancer, cervical cancer, and chronic comorbidities, are high in WLWH in Korea; therefore, further research and efforts are needed to manage these diseases.

Background: Recent guidelines about preventing surgical site infections (SSIs) recommend against the administration of prophylactic antibiotics after surgery. However, many colorectal surgeons still prefer prolonged use of prophylactic antibiotics. While minimally invasive surgery (MIS) has become the standard for colorectal cancer surgery, there were few studies about proper dose of prophylactic antibiotics in minimally invasive colorectal surgery. Methods: This is a retrospective study. All patients underwent elective colorectal cancer surgery using MIS. Intravenous cefotetan was administered as a prophylactic antibiotic.Two groups were classified according to the dose of prophylactic antibiotics: a group using a single dose preoperatively (single-dose group) and a group using a preoperative single dose plus additional doses within 24 hours after surgery (multiple-dose group). The SSI rates between the two groups were compared before and after propensity score matching (PSM).Risk factors of SSIs were assessed using univariate and multivariable analysis. Results: There were 902 patients in the single-dose group and 330 patients in the multipledose group. After PSM, 320 patients were included in each group. There were no differences in baseline characteristics and surgical outcomes except the length of hospital stay. SSI rates were not different between the two groups before and after PSM (before 2.0% vs. 2.1%, P = 0.890; after 0.9% vs. 1.9%, P = 0.505). In multivariable analysis, American Society of Anesthesiologists class 3, rectal surgery, intraoperative transfusion, and larger tumor size were identified as independent factors associated with SSI incidence. Conclusion A single preoperative dose of prophylactic antibiotics may be sufficient to prevent SSIs in elective MIS for colorectal cancer.

By investigating the characteristics and prognosis of breast cancer (BC) patients who have undergone hormone replacement therapy (HRT), this study addresses a gap in the existing literature. A total of 17,355 postmenopausal patients with BC were analyzed using data from the Korea Breast Cancer Society database (2000–2014). Among them, 3,585 (20.7%) had a history of HRT before BC diagnosis (HRT group), while 13,770 (79.3%) never received HRT (non-HRT group). The HRT group exhibited an earlier pathologic stage, lower histologic and nuclear grades, and a higher rate of breast conservation surgery compared to the non-HRT group. Furthermore, this group had a higher rate of screening participation and a greater proportion of patients with a normal or overweight body mass index (BMI). The prognosis of the HRT group was better than that of the non-HRT group, with a 5-year overall survival rate of 93.9% versus 91.7% (p < 0.001). The hazard ratio for the HRT group was 0.7 (95% confidence interval, 0.608–0.805; p < 0.001). Increased screening participation, longer HRT duration, and a normal or overweight BMI were associated with a better prognosis in the HRT group. Patients with BC who underwent HRT showed better clinicopathological characteristics and prognosis than those who did not receive HRT. The results highlighted significant differences in patients who underwent screening and those with a normal or overweight BMI. Furthermore, a longer HRT duration was associated with a better prognosis.
