Malignant pleural effusion (MPE) is one of the common complications of tumor. Acupuncture-moxibustion therapy has several advantages for treatment of MPE. Acupuncture is regarded as a complex individualized intervention, and its characteristics of TCM is difficult to be reflected by strict randomized controlled trials. The registry study provides more possibilities for the data collection of individualized diagnosis and treatment under the guidance of the overall concept and syndrome differentiation, and is more suitable for data management and collection of large samples and multi-center trials in the real-world study. It has become an opportunity to carry out real-world study of acupuncture for MPE. There are many challenges in the registry study of acupuncture for MPE. However, it is of great significance to collect real-world data of acupuncture for MPE to improve the clinical effect of MPE and provide a new clinical research method for acupuncture in tumors and related complications.

PURPOSE: Head and neck squamous cell carcinoma (HNSCC) is a deadly disease in which precision medicine needs to be incorporated. We aimed to implement next-generation sequencing (NGS) in determining actionable targets to guide appropriate molecular targeted therapy in HNSCC patients. MATERIALS AND METHODS: Ninety-three tumors and matched blood samples underwent targeted sequencing of 244 genes using the Illumina HiSeq 2500 platform with an average depth of coverage of greater than 1,000×. Clinicopathological data from patients were obtained from 17 centers in Korea, and were analyzed in correlation with NGS data. RESULTS: Ninety-two of the 93 tumors were amenable to data analysis. TP53 was the most common mutation, occurring in 47 (51%) patients, followed by CDKN2A (n=23, 25%), CCND1 (n=22, 24%), and PIK3CA (n=19, 21%). The total mutational burden was similar between human papillomavirus (HPV)–negative vs. positive tumors, although TP53, CDKN2A and CCND1 gene alterations occurred more frequently in HPV-negative tumors. HPV-positive tumors were significantly associated with immune signature-related genes compared to HPV-negative tumors. Mutations of NOTCH1 (p=0.027), CDKN2A (p < 0.001), and TP53 (p=0.038) were significantly associated with poorer overall survival. FAT1 mutations were highly enriched in cisplatin responders, and potentially targetable alterations such as PIK3CA E545K and CDKN2A R58X were noted in 14 patients (15%). CONCLUSION: We found several targetable genetic alterations, and our findings suggest that implementation of precision medicine in HNSCC is feasible. The predictive value of each targetable alteration should be assessed in a future umbrella trial using matched molecular targeted agents.

PURPOSE: With the emergence of next-generation sequencing (NGS) technology, profiling a wide range of genomic alterations has become a possibility resulting in improved implementation of targeted cancer therapy. In Asian populations, the prevalence and spectrum of clinically actionable genetic alterations has not yet been determined because of a lack of studies examining high-throughput cancer genomic data. MATERIALS AND METHODS: To address this issue, 1,071 tumor samples were collected from five major cancer institutes in Korea and analyzed using targeted NGS at a centralized laboratory. Samples were either fresh frozen or formalin-fixed, paraffin embedded (FFPE) and the quality and yield of extracted genomic DNA was assessed. In order to estimate the effect of sample condition on the quality of sequencing results, tissue preparation method, specimen type (resected or biopsied) and tissue storage time were compared. RESULTS: We detected 7,360 non-synonymous point mutations, 1,164 small insertions and deletions, 3,173 copy number alterations, and 462 structural variants. Fifty-four percent of tumors had one or more clinically relevant genetic mutation. The distribution of actionable variants was variable among different genes. Fresh frozen tissues, surgically resected specimens, and recently obtained specimens generated superior sequencing results over FFPE tissues, biopsied specimens, and tissues with long storage duration. CONCLUSION: In order to overcome, challenges involved in bringing NGS testing into routine clinical use, a centralized laboratory model was designed that could improve the NGS workflows, provide appropriate turnaround times and control costs with goal of enabling precision medicine.

The global obesity epidemic and associated metabolic diseases require alternative biological targets for new therapeutic strategies. In this study, we show that a phytochemical sulfuretin suppressed adipocyte differentiation of preadipocytes and administration of sulfuretin to high fat diet-fed obese mice prevented obesity and increased insulin sensitivity. These effects were associated with a suppressed expression of inflammatory markers, induced expression of adiponectin, and increased levels of phosphorylated ERK and AKT. To elucidate the molecular mechanism of sulfuretin in adipocytes, we performed microarray analysis and identified activating transcription factor 3 (Atf3) as a sulfuretin-responsive gene. Sulfuretin elevated Atf3 mRNA and protein levels in white adipose tissue and adipocytes. Consistently, deficiency of Atf3 promoted lipid accumulation and the expression of adipocyte markers. Sulfuretin’s but not resveratrol’s anti-adipogenic effects were diminished in Atf3 deficient cells, indicating that Atf3 is an essential factor in the effects of sulfuretin. These results highlight the usefulness of sulfuretin as a new anti-obesity intervention for the prevention of obesity and its associated metabolic diseases.

PURPOSE: Croup is known to have epidemics in seasonal and biennial trends, and to be strongly associated with epidemics of parainfluenza virus. However, seasonal and annual epidemics of croup have not been clearly reported in Korea. This study aimed to examine the seasonal/annual patterns and etiologies of childhood croup in Korea during a consecutive 6-year period. METHODS: Pediatric croup data were collected from 23 centers in Korea from 1 January 2010 to 31 December 2015. Electronic medical records, including multiplex reverse transcription polymerase chain reaction (RT-PCR) results, demographics and clinical information were cross-sectionally reviewed and analyzed. RESULTS: Overall, 2,598 childhood croup patients requiring hospitalization were identified during the study period. Among them, a total of 927 who underwent RT-PCR were included in the analysis. Males (61.5%) predominated, and most (63.0%) of them were younger than 2 years of age (median, 19 months; interquartile range, 11–31 months). Peak hospitalization occurred in 2010 and 2012 in even-numbered years, and parainfluenza virus (PIV, 39.7%) was the most common cause of childhood croup requiring hospitalization, followed by respiratory syncytial virus (14.9%), human rhinovirus (12.5%), Mycoplasma pneumonaie (10.6%), and human coronavirus (7.3%). CONCLUSION: It is concluded that croup hospitalization has a biennial pattern in even-numbered years. PIV may be the most common cause of childhood croup; however, croup epidemics could be attributed to other viruses.

OBJECTIVE: To evaluate the interpretive performance and inter-observer agreement on digital mammographs among radiologists and to investigate whether radiologist characteristics affect performance and agreement. MATERIALS AND METHODS: The test sets consisted of full-field digital mammograms and contained 12 cancer cases among 1000 total cases. Twelve radiologists independently interpreted all mammograms. Performance indicators included the recall rate, cancer detection rate (CDR), positive predictive value (PPV), sensitivity, specificity, false positive rate (FPR), and area under the receiver operating characteristic curve (AUC). Inter-radiologist agreement was measured. The reporting radiologist characteristics included number of years of experience interpreting mammography, fellowship training in breast imaging, and annual volume of mammography interpretation. RESULTS: The mean and range of interpretive performance were as follows: recall rate, 7.5% (3.3–10.2%); CDR, 10.6 (8.0–12.0 per 1000 examinations); PPV, 15.9% (8.8–33.3%); sensitivity, 88.2% (66.7–100%); specificity, 93.5% (90.6–97.8%); FPR, 6.5% (2.2–9.4%); and AUC, 0.93 (0.82–0.99). Radiologists who annually interpreted more than 3000 screening mammograms tended to exhibit higher CDRs and sensitivities than those who interpreted fewer than 3000 mammograms (p = 0.064). The inter-radiologist agreement showed a percent agreement of 77.2–88.8% and a kappa value of 0.27–0.34. Radiologist characteristics did not affect agreement. CONCLUSION: The interpretative performance of the radiologists fulfilled the mammography screening goal of the American College of Radiology, although there was inter-observer variability. Radiologists who interpreted more than 3000 screening mammograms annually tended to perform better than radiologists who did not.

Objective To analyze driver genes status and its clinical characteristics of advanced lung adenocarcinoma, then evaluate the status of first-line treatment in a single centric real-world. Methods EGFR, ALK, ROS-1 gene in 204 advanced lung adenocarcinoma tissue were tested by ARMS-PCR method. And the relationship between driver genes status and clinical characteristics was analyzed as the first line treatment in real clinical practice. Results The positive rate of driver genes status in 204 advanced lung adenocarcinoma was 53.9% (110/204) , including EGFR mutation 46.1% (94/204) , ALK positive 6.4% (13/204) and ROS1 positive 1.5% (3/204). The driving genes status was significantly correlated with gender, smoking history, tumor staging and serosal invasion (P < 0.05). There were significantly differences among the proportion of first-line standard treatment in different subgroup (P = 0.000) , the first-line standard treatment rate of EGFR mutation, ALK/ROS1 positive and drive gene negative were 77.7%, 37.5%, and 46.8% respectively. And the ratio of using 1 st generation EGFR-TKIs in all patients is 70.6% (60/85). Conclusion More than half of advanced lung adenocarcinoma have driver genes changes, and EGFR-TKI first-line treatment has higher acceptability in real-word.

OBJECTIVES: Workplace incivility is experienced by dental hygienists, who perform a variety of tasks and roles in dentistry. Therefore, to enhance the performance of dental and medical institutions, it is necessary to identify dental hygienists experiencing incivility that affects the organizational performance. METHODS: Over a two-month period from May 1 to June 30, 2015, dental hygienists from 30 dental and medical institutions in Busan, the North and South Gyeongsang Provinces, Daegu, Seoul, and the Gyeonggi Province were convenience sampled. Data, from a total of 344 participants, were analyzed using the SPSS and AMOS statistical analysis software. RESULTS: Emotional exhaustion had a partial mediating effect on the relationship between patient incivility and job performance, a full mediating effect in relation to job satisfaction, and a partial mediating effect on the association with turnover intention. Meanwhile, emotional exhaustion had a full mediating effect on the relationships between superior incivility and job performance, as well as turnover intention, while a partial mediating effect in relation to job satisfaction. CONCLUSIONS: An in-depth review of interventions that can enable a mutually respectful working environment, and promote a healthy culture among dental hygienists in dental and medical institutions is needed.
