Objective To verify the relationship between catheter-related urinary tract infection(CAUTI)and stress hyperglycemia during catheter retention in stroke patients. Methods We used nosocomial infection monitoring system to track the status of CAUTI in stroke patients in a hospital.The study cohort was all the patients who received retention catheterization from January 2016 to March 2020.According to the nested case-control design,multivariate logistic regression analysis was performed to explore the relationship between stress hyperglycemia and CAUTI in stroke patients with indwelling catheter. Results A total of 322 cases of CAUTI and 644 cases of non-CAUTI were enrolled in this study.The length of stay in the case group was(20.68 ± 3.73)d,significantly longer than that[(13.00 ± 4.01)d]in the control group(t=29.473,P <0.001).Compared with non-stress hyperglycemia,stress hyperglycemia posed a higher risk of CAUTI in the stroke patients with indwelling catheter(OR=2.020,95% CI=1.447-2.821,P=0.000)and led to the higher incidence of CAUTI in one thousand days(P<0.001). Conclusion Stress hyperglycemia in the stroke patients with indwelling catheter can significantly increase the risk of CAUTI.

BACKGROUND/AIMS: Klebsiella pneumoniae is second most common organism of gram-negative bacteremia in Korea and one of the most common cause of urinary tract infection, and intra-abdominal infection. METHODS: We compared clinical and microbiological characteristics about K. pneumoniae bacteremia in a tertiary hospital between 10 years. Group A is who had K. pneumoniae bacteremia at least one time from January 2004 to December 2005. Group B is from January 2012 to December 2013. We also analyzed antibiotic resistance, clinical manifestation of the K. pneumoniae bacteremia divided into community-acquired infections, healthcare associated infections, and nosocomial infections. RESULTS: The resistance for ampicillin, aztreonam, cefazolin, and cefotaxime significantly increased compared to 10 years ago. Extended spectrum β-lactamase positivity surged from 4.3% to 19.6%. Ten years ago, 1st, 2nd cephalosporin, and aminoglycoside were used more as empirical antibiotics. But these days, empirical antibiotics were broad spectrum such as 3rd and 4th cephalosporin. In treatment outcome, acute kidney injury decreased from 47.5% to 28.7%, and mortality decreased from 48.9% to 33.2%. In community-acquired infections, there was similar in antimicrobial resistance and mortality. In healthcare-associated and nosocomial infections, there was significantly increasing in antibiotic resistance, decreasing in mortality, and acute kidney injury. CONCLUSIONS: In community-acquired infections, broader antibiotics were more used than 10 years ago despite of similar antimicrobial resistance. When K. pneumoniae bacteremia is suspected, we recommend to use the narrow spectrum antibiotics as initial therapy if there are no healthcare-associated risk factors, because the antibiotic resistance is similar to 10 years ago in community-acquired infections.

Achromobacter xylosoxidans is a non-fermentative, aerobic, oxidase, and catalase-positive Gram-negative rod similar to Pseudomonas species. This organism colonizes aquatic environments and can cause nosocomial infections, especially in patients with immune deficiency such as human immunodeficiency virus infection, cancer, cystic fibrosis, neutropenia, and immunoglobulin M deficiency. Infections are found as bacteremia, pneumonia, meningitis, urinary tract infection, abscess formation, and osteomyelitis. It is known that most effective antibiotics are piperacillin/tazobactam, meropenem, and trimethoprim/sulfamethoxazol. But there is no optimal antibiotic therapy so far. We present a case of Achromobacter xylosoxidans bacteremia in a 13-month-old Korean girl who had past history of neutropenia.

PURPOSE: Patients in the intensive care unit (ICU) are more susceptible to nosocomial infections, including central line-associated bloodstream infection (CLABSI), surgical site infection, urinary tract infection or ventilator-associated pneumonia. This study is a comparative analysis of how central venous catheter (CVC) management staff affects CLABSI. METHODS: We performed a two-phase review of all patients transferred to the surgical ICU (SICU) from January 2013 to June 2014. CVC management staff was introduced in October 2013. Electronic medical records provided the data for a comparative analysis of incidence rates and risks of CLABSI, as well as the subjects' general characteristics. RESULTS: This study included 248 patients before the introduction of a CVC management staff member and 196 patients after the introduction. General patient characteristics before and after the CVC management staff was in place did not differ significantly. The CLABSI rate decreased by 4.61 cases/1,000 device days after the introduction (6.26 vs. 1.65; odds ratio, 4.47; 95% confidence interval, 1.39~14.37; p=0.009). However, the mortality rate and length of ICU stay did not change after CVC management staff was in place (12.9% vs. 10.7%, p=0.480; 16.00±24.89 vs. 15.87±18.80, p=0.954; respectively). CONCLUSION: In this study, the introduction of CVC management staff effectively reduced CLABSI rates in current ICU system.

PURPOSE: Health careeassociated infections increase disease prevalence and mortality and are the main reason for the hospitalization of the elderly. However, the management of underlying infections in patients hospitalized in long-term care hospitals (LTCHs) is insufficient, and the transfer of these poorly managed patients to the emergency room (ER) of an acute care hospital can lead to rapid spread of infection. This study investigated the risk factors associated with an ER visit due to infections that developed in LTCHs. METHODS: The electronic medical records of patients who were transferred to the ER of a university hospital in South Korea were used. Infection prevalence, causative infectious agent, and antibiotic sensitivity were assessed. The associations between patient characteristics and hospital-associated infections were examined using multiple logistic regression analyses. RESULTS: Among the 483 patients transferred to the ER during the study period, the number of infection cases was 197, and 171 individuals (35.4%) had one or more infections, with pneumonia being the most common (52.8%), followed by urinary tract (21.3%) and bloodstream (17.8%) infections. Patients with bedsores, fever, an indwelling catheter, and a higher nursing need were more likely to be seen in the ER because of infectious disease from an LTCH. CONCLUSION: Both an intensive care system and surveillance support should be established to prevent infections, particularly in high-risk patients at LTCHs.

PURPOSE: This study aimed to assess the long-term clinical outcome of laparoscopic Nissen fundoplication (LNF) in children according to their neurologic status. METHODS: The study retrospectively analyzed the data of 82 children (62 neurologically impaired and 20 neurologically normal children with primary gastroesophageal reflux disease) who had undergone LNF between 2003 and 2012. The main outcome measures were the occurrence of recurrence that required reoperation and post-procedure complications such as infections, pneumonia, and gastrointestinal complications including ileus, dysphagia, and delayed gastric emptying. RESULTS: The median age at the time of the LNF was 25 months (range, 1-192 months), and the median of body weight was 10.0 kg (range, 2.8-37.0 kg). The average weight gain was 1.55±1.68 kg at 6 months, 3.32±2.30 kg at 1 year, and 5.63±4.22 kg at 2 years after surgery. Six (9.7%) of the 62 neurologically impaired patients and two (10.0%) of neurologically normal lost their body weight or had no weight changes. Eight (12.9%) of the 62 neurologically impaired children had required redo surgery because of gastroesophageal reflux disease recurrences, while 2 (10.0%) of the 20 neurologically normal children had experienced recurrences. In the neurologically impaired children, the postoperative complications included pneumonia (n=1), wound infection (n=1), urinary tract infection (n=1), dysphagia (n=1), delayed gastric emptying (n=1), and ileus (n=2). All of these complications were not found in the neurologically normal group, except for only one case of infectious colitis. However, there was no statistically significant difference between the two groups in postoperative complications. CONCLUSION: The outcomes of laparoscopic fundoplication were similar in the neurologically impaired children and in the neurologically normal children.

Healthcare-associated infections are infections that develop within a hospital and were not present or incubating upon admission. Almost all healthcare-associated infections become evident 2 days after admission. A patient may develop a healthcare-associated infection after hospital discharge if the pathogen was acquired in the hospital. Healthcare-associated infections most frequently involve the urinary tract, surgical sites, the lower respiratory tract, and the bloodstream, with Escherichia coli and Staphylococcus aureus being the most common pathogens identified. The microorganisms of healthcare-associated infections are usually more antimicrobial resistant than the same ones of community origin. Prevention of healthcare-associated infections, as well as those related to intravenous devices, requires standard infection control procedures: in other words, universal precautions including hand hygiene by all healthcare workers. Management of healthcare-associated infections includes supportive care, underlying disease treatment, displacement of an intravenous or intraurethral device and appropriate antimicrobial therapy. Healthcare-associated infections are not only a personal health issue but also a public health issue; therefore, the public and the government should cooperate to contribute to developing and implementing rational solutions for these infections.

To evaluate the efficacy and safety of modified pedicle subtraction osteotomy for treatment of thoracolumbar old fracture with kyphosis.
 Methods: From January 2003 to January 2013, 58 patients of thoracolumbar kyphosis, who underwent modified pedicle subtraction osteotomy, were reviewed. Among them, 45 cases underwent initial operation and 13 cases underwent revision surgery. Preoperative and postoperative kyphotic Cobb's angle, score of back pain, as well as the incidence of complication were accessed by using visual analogue scale (VAS) and Oswestry disability index (ODI).
 Results: Mean follow-up duration was 42 months (range, 24-60 months). Average operative time was 258 min (range, 190-430 min), while average bleeding was 950 mL (range, 600-1 600 mL). All the patients were significantly improved in function and self-image, and achieved kyphosis correction with 17.9°± 4.3°. VAS of low back pain was decreased by 3.1±0.6; ODI was dropped by 25.3%±5.5%. 3 patients (5.2%) suffered anterior thigh numbness and got recovery after 3 months of follow-up. Complications happened in 19 patients, including 12 with cerebrospinal fluid leak, 4 with superficial wound infection, and 3 with urinary tract infection. All these complications were managed properly and none of them underwent reoperation.
 Conclusion: Modified pedicle subtraction osteotomy is a safe and effective technique for the treatment of old fracture with kyphosis.

Prevention of healthcare-associated infection (HAI) is an essential part of patient safety. HAIs are associated with significant mortality, morbidity, and increasing healthcare cost. Major HAIs include urinary tract infection, pneumonia, surgical site infection, bacteremia, and C. difficile colitis. Surveillance for HAIs is essential to prevent these infections. Active strategies, such as the 'bundle' approach, should be implemented for the effective prevention of HAIs. The Korean regulatory certification system for hospitals is a powerful driver in the maintenance of the infection surveillance, control and prevention process. Additional driving forces for the reduction of HAIs include financial incentives and convincing clinical practice guidelines. Therefore, there is a need for solid regulatory and financial support and a suitable cultural environment for the prevention of HAIs.
