Background: This study compared the treatment outcomes of patients with multidrug-resistant tuberculosis (MDRTB) before and after the implementation of public-private mix (PPM). Factors affecting treatment success were also investigated. Methods: Data from culture-confirmed pulmonary MDR-TB patients who commenced MDR-TB treatment at Pusan National University Hospital between January 2003 and December 2017 were retrospectively reviewed. Patients were divided into two groups in terms of PPM status: pre-PPM period, patients who commenced MDR-TB treatment between 2003 and 2010; and post-PPM period, patients treated between 2011 and 2017. Results: A total of 176 patients were included (64 and 112 in the pre- and post-PPM periods, respectively). 36.9% of the patients were resistant to a fluoroquinolone or a second-line injectable drug, or both. The overall treatment success rate was 72.7%. The success rate of post-PPM patients was higher than that of pre-PPM patients (79.5% vs. 60.9%, p=0.008). Also, loss to follow-up was lower in the post-PPM period (5.4% vs. 15.6%, p=0.023). In multivariate regression analysis, age ≥65 years, body mass index ≤18.5 kg/m<sup>2</sup>, previous TB treatment, bilateral lung involvement, and extensively drug-resistant (XDR)- or pre-XDR-TB were associated with poorer treatment outcomes. However, the use of bedaquiline or delamanid for ≥1 month increased the treatment success. Conclusion: The treatment success rate in MDR-TB patients was higher in the post-PPM period than in the pre-PPM period, particularly because of the low rate of loss to follow-up. To ensure comprehensive patient-centered PPM in South Korea, investment and other support must be adequate.

Background: There are few data regarding effect of early tracheostomy on clinical outcomes in our country. Our study aimed to investigate effect of early tracheostomy on clinical outcomes (including long-term mortality) in patients with prolonged acute mechanical ventilation (PAMV, ventilator care ≥ 96 hrs). Methods: Data were obtained retrospectively from 575 patients, (69.4% male; median age 68 years) who hospitalized at a medical intensive care unit (ICU) of a single university-affiliated tertiary care hospital over 9 years (between March 2008 and February 2017). Early tracheostomy was defined as ≤ 10 days after translaryngeal intubation. Results: Their hospital and one-year cumulative mortality rate after ICU admission were 38.6 % (n=222) and 61.2 % (n=352), respectively. Also, one hundred forty-three patients (24.9%) underwent early tracheostomy, while others classified with late (n=115, 20.0 %) or no tracheostomy group (n=317, 55.1%). When total patients were divided two groups (early versus late or no tracheostomy), there were no significant differences of Acute Physiology and Chronic Health Evaluation II [median 22 interquartile range (16-25) vs 19 (15-25), p=0.172] and Sequential Organ Failure Assessment scores [7 (5-10) vs 6 (4-9), p=0.737] on ICU admission between both groups. However, early tracheostomy group showed higher medical costs during hospital stay [26,609 (17,634-44,066) vs 21,536 (13,974- 36,509) USD, p=0.013], ICU rehabilitation (46.2 vs 20.1%, p<0.001) and lower hospital mortality (21.7 vs 44.2% p<0.001). In stepwise multivariable Cox-proportional hazard model, early tracheostomy [Hazard ratio 1.550 (95% Confidence interval 1.197-2.006), p=0.011] was associated with one-year survival improvement. Conclusions: In our study, early tracheostomy group showed higher total hospital cost during hospital stay. Also, early tracheostomy was associated with higher hospital and one-year survival improvement.

In this study, we compared a cantilever piezoelectric energy harvester with a fixed-fixed piezoelectric energy harvester and analyzed the output powers of two harvesters. In two harvesting systems, the same piezoelectric material was used for giving identical condition. In order to exert input energy, we fell steel balls on the piezoelectric harvester. The weights of steel balls were 2g and 4g. The cantilever piezoelectric energy harvester generated the maximum power of 6.494 mW with a 4g steel ball and the fixed-fixed piezoelectric energy harvester produced the maximum power of 8.934 mW. The fixed-fixed piezoelectric energy harvester produced higher maximum power than the cantilever one in all cases. The results shows that 33-mode is more dominant than 31-mode.

Purpose: The incidence of drug-induced liver injury (DILI) has been increasing; however, few algorithms are available to identify DILI in electronic health records (EHRs). We aimed to identify and evaluate DILI with an appropriate screening algorithm. Methods: We collected data from 3 university hospitals between June 2015 and May 2016 using our newly developed algorithm for identifying DILI. Among patients with alanine transferase (ALT) ≤ 120 IU/L and total bilirubin (TB) ≤ 2.4 mg/dL in blood test results within 48 hours of admission, those who either had 1) ALT > 120 IU/L and TB > 2.4 mg/dL or 2) ALT > 200 IU/L at least once during hospitalization were identified. After excluding patients with liver disease-related diagnosis at discharge, medical records were retrospectively reviewed to evaluate epidemiological characteristics of DILI. Results: The total number of inpatients was 256,598, of whom 1,100 (0.43%) were selected by the algorithm as suspected DILI. Subsequently, 365 cases (0.14% of total inpatients, 95% confidence interval, 0.13–0.16) were identified as DILI, yielding a positive predictive value of 33.1%. Antibiotics (n = 214, 47.2%) were the major class of causative drug followed by chemotherapeutic agents (n = 87, 19.2%). The most common causative drug was piperacillin-tazobactam (n = 38, 8.4%); the incidence of DILI by individual agent was highest for methotrexate (19.4 cases/1,000 patients administered the drug). Common reasons for excluding suspected DILI cases were ischemic hepatitis and postoperative liver dysfunction. Conclusions: Using our EHR-based algorithm, we identified that approximately 0.14% of patients developed DILI during hospitalization. Further studies are needed to modify criteria for more accurate identification of DILI.

Background: Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease characterized by persistent airflow limitation. Therefore, both work ability and workday length may be affected in individuals with this disease. We studied a worker with suspected COPD and assessed fitness to work using post-bronchodilator spirometry, symptom assessment scales, and the exercise stress test. Case report: The patient was a 58-year-old man due to work as a field supervisor in the ship construction sector. He had a 40 pack-year smoking history and experienced occasional dyspnea when climbing stairs. He visited this hospital to receive cardiopulmonary function tests and to determine his ability to work. Post-bronchodilator spirometry revealed severe irreversible airway obstruction corresponding to a modified Medical Research Council grade of 2 on the dyspnea scale. His COPD Assessment Test score was 12, placing him in patient group D (high risk, more symptoms) based on the Global Initiative for Chronic Obstructive Lung Disease classification system. His maximum oxygen uptake (VO2max) was determined to be 19.16 ml/kg/min, as measured by the exercise stress test, and his acceptable workload for 8 h of physical work was calculated to be 6.51 ml/kg/min. His work tasks required an oxygen demand of 6.89 ml/kg/min, which exceeded the acceptable workload calculated. Accordingly, he was advised to adjust the work tasks that were deemed inappropriate for his exercise capacity. Conclusion: As COPD incidence is expected to rise, early COPD diagnosis and determination of fitness to work is becoming increasingly important. Performing the exercise stress test, to evaluate the functional capacity of workers with COPD, is considered an acceptable solution.

Salmonella is one of the most important bacterial pathogens responsible for many zoonotic food-related infectious diseases. Quantitative detection of the foodborne Salmonella contamination in various food sources is therefore critical for preventing the related disease outbreaks. In this study, we developed and evaluated a reliable real-time polymerase chain reaction (RT-PCR) assay to detect the Salmonella contamination quantitatively. The experimental results showed that our invA gene-specific quantitative RT-PCR (qRT-PCR) assay provides a strong correlation between the Cq values and the direct plate counts of Salmonella species in the artificially formulated samples. Further study may be necessary to identify more accurate correlation and equation that can apply to Salmonella spp.
