PURPOSE: The aim of this study was to verify the effects of daily 2% chlorhexidine gluconate (CHG) bathing on the acquisition of multidrug-resistant organisms (MDRO) and healthcare-associated infection (HAI) in a medical intensive care unit (MICU). METHODS: The study was a randomized controlled group posttest only design, involving 91 patients in MICU at a tertiary hospital (47 patients in the experimental group and 44 patients in the control group). The 2% CHG bathing was performed daily according to bathing protocol to the patients in the experimental group, and traditional bath was performed every three days to those in the control group. Fisher's exact test and χ² test were used to analyze the data. RESULTS: MDRO were found in 6 patients of the experimental group and in 15 patients of the control group. The difference was statistically significant (p=.016). HAI occurred in 2 patients of the experimental group and in 7 patients of the control group. The difference was not statistically significant (p=.084). CONCLUSION: The results confirmed that daily bathing with CHG was effective in reducing the incidence of MDRO acquisition. Therefore, it is expected that daily bathing with CHG will be used as an effective nursing intervention to reduce the incidence of MDRO acquisition.

Purpose: The preemptive use of renin-angiotensin system (RAS) inhibitors may reduce doxorubicin (DOX)-related cardiotoxicity. Using the national insurance claims data of Korea, this study compared cardiovascular (CV) outcomes following the use of four major antihypertensive drug classes in patients with hypertension and breast cancer who underwent DOX-containing chemotherapy. Methods: A total of 4,722 patients with hypertension and breast cancer who underwent DOXcontaining chemotherapy were included. The outcomes were compared between patients who used RAS inhibitors, calcium channel blockers (CCBs), beta-blockers (BBs), and thiazide and thiazide-like diuretics (TDs). The primary outcome was a composite of incident heart failure and serious ventricular arrhythmias, including ventricular tachycardia and fibrillation, ischemic heart disease, and stroke. Results: In the propensity score-matched population, there were no significant differences in the primary outcome between RAS inhibitor and CCB users; however, patients with diabetes who used CCBs had a worse primary outcome than those who used RAS inhibitors (adjusted hazard ratio [aHR], 1.93; 95% confidence interval [CI], 1.06–3.51). BB and TD users had a worse primary outcome compared with RAS inhibitor (aHR, 1.88; 95% CI, 1.30–2.71 in BB users and aHR, 2.55; 95% CI, 1.37–4.75 in TD users) or CCB (aHR, 1.54; 95% CI, 1.09–2.16 in BB users and aHR, 2.08; 95% CI, 1.13–3.82 in TD users) users. Conclusion RAS inhibitors are preferred for the treating hypertension and improving CV outcomes in patients with hypertension and breast cancer undergoing DOX-containing chemotherapy, particularly in patients with comorbid diabetes. However, CCBs are equivalent to RAS inhibitors and are more favorable than BBs and TDs in terms of improving CV outcomes.

Sacrococcygeal teratoma is the most common congenital tumor in neonates, and is reported in approximately 1/35,000 to 1/40,000 live births. Oligodendroglioma is a rare central nervous system tumor that is usually found in the cerebral hemisphere of young and middle aged adults. When associated with a teratoma, it is mainly identified in ovarian teratoma in adolescents and adults. We describe a rare case of a preterm infant with oligodendroglioma in a mature sacrococcygeal teratoma. The male neonate was born at a gestational age of 30 weeks with a protruding mass in the sacrococcygeal region. Pelvic magnetic resonance imaging showed a sacrococcygeal teratoma of approximately 11 cm comprising fat components and skeletal structure, that extended from the anterior part of the sacrum to the abdominal cavity. Radical resection was performed at 36 days of age. Macroscopically, the resected intra-abdominal mass had the characteristics of a cystic lesion, and the intrapelvic mass was a predominantly solid mixed cystic-solid lesion. Histologically, this solid lesion in the intrapelvic mass was composed of mature glial tissue, which comprised as a proliferation of monotonous cells with small and round nuclei, surrounded by a perinuclear halo (“fried egg” appearance). Additionally, these cells were immunohistochemically positive for glial fibrillary acidic protein. These findings confirmed the diagnosis of oligodendroglioma in sacrococcygeal mature teratoma. After the treatment, no recurrence was observed during the follow-up period, and no additional intervention was required. However, the patient is undergoing treatment for voiding dysfunction caused by a neurogenic bladder.

BACKGROUND: Ductal adenocarcinoma (DAC) of the prostate is an uncommon histologic subtype whose prognostic factors and immunoprofile have not been fully defined. METHODS: To define its prognostic factors and immunoprofile, the clinicopathological features, including biochemical recurrence (BCR), of 61 cases of DAC were analyzed. Immunohistochemistry was performed on tissue microarray constructs to assess the expression of prostate cancer-related and mammalian target of rapamycin (mTOR) signaling-related proteins. RESULTS: During the median follow-up period of 19.3 months, BCR occurred in 26 cases (42.6%). DAC demonstrated a wide expression range of prostate cancer-related proteins, including nine cases (14.8%) that were totally negative for pan-cytokeratin (PanCK) immunostaining. The mTOR signaling-related proteins also showed diverse expression. On univariate analysis, BCR was associated with high preoperative serum levels of prostate-specific antigen (PSA), large tumor volume, predominant ductal component, high Gleason score (GS), comedo-necrosis, high tumor stage (pT), lymphovascular invasion, and positive surgical margin. High expressions of phospho-mTOR (p-mTOR) as well as low expressions of PSA, phospho-S6 ribosomal protein (pS6) and PanCK were associated with BCR. On multivariable analysis, GS, pT, and immunohistochemical expressions of PanCK and p-mTOR remained independent prognostic factors for BCR. CONCLUSIONS: These results suggest GS, pT, and immunohistochemical expressions of PanCK and p-mTOR as independent prognostic factors for BCR in DAC. Since DAC showed diverse expression of prostate cancer–related proteins, this should be recognized in interpreting the immunoprofile of DAC. The diverse expression of mTOR-related proteins implicates their potential utility as predictive markers for mTOR targeted therapy.

PURPOSE: This study aimed to identify the factors influencing human papillomavirus (HPV) vaccination adoption stages using the Precaution Adoption Process model. METHODS: A total of 173 female university students from B metropolitan city participated. Demographics, factors contributing to action, knowledge, health beliefs, and self-efficacy related to the HPV vaccination were measured. The collected data were analyzed using descriptive statistics and multiple logistic regression analysis using SPSS for Windows version 21.0. RESULTS: Factors that contributed to the transition from the unaware and unengaged stages to the undecided about action stage included age, economic status, experience of recommendation from doctors, perceived severity of cervical cancer, and perceived barriers. Factors that contributed to the transition from the undecided about action stage to the deciding to act stage were perceived benefit and self-efficacy of the HPV vaccination. Factors that contributed to the transition from the deciding to act stage to the acting and maintenance stages were experience of recommendation from doctors and perceived severity of cervical cancer. CONCLUSION: These results suggest that aggressive HPV vaccination campaigns increase awareness. Further studies should develop tailored strategies for promoting HPV vaccination that emphasize health beliefs and self-efficacy.

Eosinophilia is most frequently associated with asthma, allergic conditions, and parasitic infestation. Eosinophilia can also be associated with many forms of cancer. However, eosinophilia is infrequently associated with solid tumors. We experienced a 73-year-old-woman with eosinophilia as a manifestation of paraneoplastic syndrome that was combined with non-small-cell lung cancer (NSCLC). Initially, she was diagnosed with idiopathic hypereosinophilic syndrome, but was diagnosed with NSCLC 1 month later. Here, we report this case with a brief review of the literature.

The global incidence of breast cancer is on the rise, a trend also observed in South Korea.However, thanks to the rapid advancements in anticancer therapies, survival rates are improving. Consequently, post-treatment health and quality of life for breast cancer survivors are emerging as significant concerns, particularly regarding treatment-related cardiotoxicity. In this review, we delve into the cardiovascular complications associated with breast cancer treatment, explore surveillance protocols for early detection and diagnosis of late complications, and discuss protective strategies against cardiotoxicity in breast cancer patients undergoing anticancer therapy, drawing from multiple guidelines.

The purpose of this study was to evaluate the structural characteristics of the thread length of orthodontic mini-screws and the effects of insertion and removal torques according to the formation of the cutting flute. Two types of mini-screws were made, with a thread length of 6.0 mm and a thread length of 3.3 mm. In order to examine the effect of flute formation, the experiment group was divided into a miniscrew test group with flute formation and an experiment group without flute formation. To evaluate the effect of flute formation, two flutes were formed at 180°on the circumference, and at the tip of the mini screw, up to 4 mm for thread length of 6.0 mm and 2.4 mm for thread length of 3.3 mm. A biomechanical test block formed of 2 mm cortical bone and 10 mm cancellous bone was used to eliminate the influence of the difference in cortical bone thickness and bone density according to the insertion site. 1 mm diameter guide hole was drilled on the test block and the mini-screw was placed vertically. Using a 0.1 N·cm precision digital torque gauge, the maximum torque value was recorded at this time by embedding it to the top of the screw under a static load of 1.2 kg and the value when it was removed in the opposite direction. The insertion torque values for the 6.0 mm and 3.3 mm length mini screws were (29.53±1.84) N·cm and (26.84±2.15) N·cm, and the removal torque values are (14.50±1.37) N·cm and (13.15±2.89) N·cm, respectively.There were no statistically significant differences (P>0.05). The flute of 6.0 mm mini-screws had no statistically significant difference in both insertion and removal torque values and increased to (30.13±1.97) N·cm and (18.65±1.10) N·cm (P>0.05). In experiments with 3.3 mm mini-screws, the insertion and removal torque values decreased to (20.99±3.94) N·cm and (11.32±2.03) N·cm, respectively, showing a statistically significant decrease only in the insertion torque values (P<0.05). The insertion and removal torque values of the mini-screw were not significantly increased even when the screw length was doubled, and the flute formation effect was different with the screw length.

The leading cause of morbidity and mortality in patients with acromegaly is cardiovascular complications. Myocardial exposure to excessive growth hormone can cause ventricular hypertrophy, hypertension, arrhythmia, and diastolic dysfunction. However, congestive heart failure as a result of systolic dysfunction is observed only rarely in patients with acromegaly. Most cases of acromegaly exhibit high levels of serum insulin-like growth factor-1 (IGF-1). Acromegaly with normal IGF-1 levels is rare and difficult to diagnose. Here, we report a rare case of an acromegalic patient whose first clinical manifestation was severe congestive heart failure, despite normal IGF-1 levels. We diagnosed acromegaly using a glucose-loading growth hormone suppression test. Cardiac function and myocardial hypertrophy improved 6 months after transsphenoidal resection of a pituitary adenoma.
