- Abstract
Secondary hyperparathyroidism (SHPT) is common in end-stage renal disease (ESRD) patients, and it can suppress erythropoiesis. We aimed to investigate the relationship between the consumption of erythropoiesis-stimulating agents (ESAs) and parathyroidectomy (PTX) in ESRD patients with SHPT and to determine the predictors for anemia improvement. The current standard of chronic kidney disease anemia therapy relies on the prescription of iron supplementation, and ESA. We retrospectively analyzed 81 ESRD patients with PTX at Ditmanson Medical Foundation Chiayi Christian Hospital from July 2004 to Dec 2018. The requirement of ESA therapy markedly declined from a dose of 41.6 (interquartile range [IQR], 0−91.2) to 10.3 (IQR, 0−59.5, p = 0.001) unit/kg/week. In addition, 63.7% of patients required iron replacement therapy preoperatively and the proportion reduced to 52.5% after PTX (p < 0.001). The hemoglobin (Hb) level showed an insignificant change from a median value of 10.7 g/dL (9.5−11.6 g/dL) before PTX to 10.5 g/dL (9.6−11.2 g/dL) at 6 months after PTX. A preoperative Hb level ≤ 10 mg/dL (odds ratio [OR], 20.1; 95% confidence interval [CI], 4.71−125, p < 0.001) and transferrin saturation (TSAT) < 25% (OR, 12.8; 95% CI, 2.51−129, p < 0.001) were predictors for anemia improvement. Our study demonstrated that PTX markedly decreased the requirement of ESA. Patients with a low preoperative Hb level or low TSAT showed an increase in the Hb level after PTX. PTX may be considered not only for SHPT with refractory anemia but also for high ESA-dependent patients.

- Abstract
Lung cancer is one of the most common cancers and the leading cause of death in humans worldwide. Non-small-cell lung cancer (NSCLC) accounts for approximately 85% of lung cancer cases and is often diagnosed at a late stage. Among patients with NSCLC, 50% die within 1 year after diagnosis. Even with clinical intervention, the 5-year survival rate is only approximately 20%. Therefore, the development of an advanced therapeutic strategy or novel agent is urgently required for treating NSCLC. Berberine exerts therapeutic activity toward NSCLC; therefore, its activity as an antitumor agent needs to be explored further. In this study, three terpenylated-bromide derivatives of berberrubine were synthesized and their anti-NSCLC activities were evaluated. Each derivative had higher anti-NSCLCs activity than berberrubine and berberine. Among them, 9-O-gernylberberrubine bromide (B4) and 9-O-farnesylberberrubine bromide (B5) showed greater growth inhibition, cell-cycle regulation, in vitro tumorigenesis suppression, and tumor migration reduction. In addition, some degree of apoptosis and autophagic flux blocking was noted in the cells under B4 and B5 treatments. Our study demonstrates that the berberrubine derivatives, B4 and B5, exhibit impressive anti-NSCLC activities and have potential for use as chemotherapeutic agents against NSCLC.

- Abstract
Lung cancer is the leading cause of death in the world, and the most common type of lung cancer is non-small-cell lung cancer (NSCLC), accounting for 85% of lung cancer. Patients with NSCLC, when detected, are mostly in a metastatic stage, and over half of patients diagnosed with NSCLC die within one year after diagnosis; the 5-year survival rate is 24%. However, in patients with metastatic NSCLC, the 5-year survival rate is 6%. Therefore, development of a new therapeutic agent or strategy is urgent for NSCLCs. Berberine has been illustrated to be a therapeutic agent of NSCLC. In the present study, we synthesized six derivatives of berberine, and the anti-NSCLC activity of these agents was examined. Some of them exert increasing proliferation inhibition comparing with berberine. Further studies demonstrated that two of the most effective agents, 9- O -decylberberrubine bromide (B6) and 9- O -dodecylberberrubine bromide (B7), performed cell cycle regulation, in-vitro tumorigenesis inhibition and autophagic flux blocking, but not induction of cellular apoptosis in NSCLC cells. Moreover, B6 and B7 were determined to be green fluorescent and could be penetrated and localized in cellular mitochondria. Herein, B6 and B7, the berberine derivatives we synthesized, revealed better anti-NSCLC activity with berberine and may be used as therapeutic candidates for the treatment of NSCLCs.

- Abstract
Background: Critically ill pediatric patients are considered at high risk for medication errors. Although much research focuses on the actual errors, equally important are medication errors that, although intercepted, carried the potential for an adverse drug event. The aim of this study was to determine the occurrence of prescribing errors and potential adverse drug events (pADEs) in a local pediatric intensive and critical care unit (PICU) in Hong Kong. Our secondary objective was to determine the type of error, nature of medication involved and the time of error occurrence., Methods: We conducted a prospective observational chart review among patients in a pediatric intensive and high dependency unit between January 16, 2015 and April 20, 2015. Medical charts for each patient were reviewed for the occurrence of a prescribing error or pADE. Each pADE was assessed for the type of error, the classification of agent involved, clinical severity of the error, and the time the error occurred., Results: Forty-one patients with a mean age of 3.2 years were included in our study. Of these patients, 19 (46.3%) experienced at least one pADE. We identified 131 pADEs, 129 of which were prescribing errors conferring a rate of 6.8 errors per affected patient or 3.1 errors per patient admitted to the PICU. The most common error found in the study was incorrect dose calculation (48.1%), with intravenous fluids (41.7%), cardiovascular agents (15.0%), and anti-infectives (12.5%) the most common agents involved with an error. The majority of the pADEs in our study were either clinically serious (33.1%) or significant (44.9%) in nature. Nearly one in every four errors required monitoring and/or intervention to prevent harm, and almost all (96.9%) of the prescribing errors were intercepted before reaching the patient., Conclusion: This study highlights incorrect dose calculation as the most common prescribing error in a pediatric critical care setting. Intravenous fluids, cardiovascular agents, and anti-infectives were the classes of medication most commonly involved with a pADE. Due to the high-risk nature of medications used and the critical condition of these patients, more than three-quarters of pADEs were considered to be clinically serious or significant in causing patient harm.

- Abstract
Our study sought to review our experience from biportal to uniportal video-assisted thoracoscopic surgery (VATS) major lung resection. Lessons we learned from the evolution regarding technical aspects were also discussed.We retrospectively reviewed patients who underwent VATS lobectomy or segmentectomies in Ditmanson Medical Foundation Chia-Yi Christian Hospital, Chia-Yi, Taiwan, during January 2012 and December 2014. Patient clinical profiles, surgical indications and procedures, postoperative course, and oncological parameters were analyzed and compared between the biportal and uniportal groups.A total of 121 patients were enrolled in this study with median follow-up of 19.5 ± 11.6 months for all patients and 22.5 ± 11.5 months for primary lung cancer patients. Operation time (146.1 ± 31.9-158.7 ± 40.5 minutes; P = 0.077), chest drainage time (3.8 ± 3.3-4.4 ± 2.4 days; P = 0.309), conversion to thoracotomy rate (2.2%-2.6%; P = 0.889), and complication rate (15.6%-19.7%; P = 0.564) were equal between the groups, whereas blood loss (96.7 ± 193.2-263.6 ± 367; P = 0.006) was lower in the uniportal group. For lung cancer cases, there were no statistical differences in the histology, cancer staging, mediastinal lymph node dissection stations, numbers of dissected N1, N2, and overall lymph nodes between uniportal and biportal groups.Our preliminary data showed that uniportal VATS anatomical lung resection is as feasible, equally safe, and of comparative oncological clearance efficacy to biportal VATS., Competing Interests: The authors declared no conflicts of interest.
