Surgery is so far the most effective treatment for early-stage non-small cell lung cancer (NSCLC). Since the 1990s, the pathology spectrum of early-stage lung cancer has gradually changed because of the increased detection of ground-glass opacity (GGO). The findings from preoperative thin-section computed tomography are strong predictors for the invasiveness and lymph node involvement of GGO, and limited surgery is believed to be implemented safely for radiological less invasive lesions, which calls into question the dominance of lobectomy. After the JCOG0201 trial establishing the radiologic criteria of pathological noninvasiveness for lung adenocarcinoma, the Japan Clinical Oncology Group (JCOG) and the West Japan Oncology Group (WJOG) have successively carried out a series of prospective imaging-guided trials to investigate the optimal surgical procedure for early-stage lung cancer. JCOG0804, was a single-arm, non-randomized, confirmatory trial to evaluate the efficacy and safety of sublobar resection (wedge resection and segmentectomy) for GGO dominant peripheral lung cancer. The primary end point was 5-year relapse-free survival. JCOG0802/WJOG4607L, was a multicentre, open-label, phase 3, randomized, controlled, non-inferiority trial to investigate if segmentectomy was non-inferior to lobectomy in patients with small-sized peripheral NSCLC. The primary endpoint was 5-year overall survival. JCOG1211 was also a non-randomized confirmatory trial to confirm the efficacy of a segmentectomy for clinical T1N0 lung cancer with dominant GGO. The primary endpoint was 5-year relapse-free survival. The findings of JCOG0804 and JCOG0802, and the primary analysis results of JCOG1211 have been officially published. This article systematically reviewed and interpreted the results of the JCOG lung cancer surgery trial series.

PURPOSE: This study aims to examine the effects of nursing interventions based on the Extended Theory of Planned Behavior (ETPB) regarding self-efficacy for exercise (SEE), physical activity (PA), physical function (PF), and quality of life (QOL) in patients with lung cancer who have undergone pulmonary resection.METHODS: This quasi-experimental study was conducted between July 2015 and June 2018 in two university-affiliated hospitals. The intervention included pre-operative patient education, goal setting (action and coping planning), and feedback (behavior intention and perceived behavioral control). The intervention group (IG) (n=51) received nursing interventions from the day before surgery to 12 months after lung resection, while the comparison group (CG) (n=36) received usual care. SEE, PA, PF (dyspnea, functional status, and 6-minute walking distance [6MWD]), and QOL were measured before surgery and at one, three, six, and 12 months after surgery. Data were analyzed using the χ² test, Fisher's exact test, Mann–Whitney U test, t-test, and generalized estimation equations (GEE).RESULTS: There were significant differences between the two groups regarding SEE (χ²=13.53, p=.009), PA (χ²=9.51, p=.049), functional status (χ²=10.55, p=.032), and 6MWD (χ²=15.62, p=.004). Although there were no time or group effects, the QOL mental component (Z=−2.78, p=.005) of the IG was higher than that of the CG one month after surgery. Interventions did not affect dyspnea or the QOL physical component.CONCLUSION: The intervention of this study was effective in improving SEE, PA, functional status, and 6MWD of lung cancer patients after lung resection. Further extended investigations that utilize ETPB are warranted to confirm these results.

To systematically evaluate the adverse drug reaction(ADR) of Tripterygium Glycosides Tablets(TGT) in the treatment of rheumatoid arthritis(RA). Four Chinese databases(CNKI, VIP, WanFang, SinoMed) and three English databases(Cochrane Library, EMbase, PubMed), from the time of database establishing to August 2019, were systematically retrieved to collect literature on the treatment of all types of RA with TG. Screening literature and extracting data according to inclusion and exclusion criteria. All studies were assessed by using internationally recognized methodological quality assessment tools or reporting quality evaluation criteria, with data being extracted and Meta-analyzed. There were 79 studies included, randomized controlled trials(RCT) containing TGT in the treatment group, non-randomized controlled trials(non-RCT), case series, case reports, and RCT containing TGT only in the control group were covered. There were in the control group; 765 ADR of 2 214 patients in 30 RCT(treatment group given TGT), 11 non-RCT and 7 case reports. The results of Meta-analysis of these 48 literatures showed that the overall incidence of ADRs was 0.23(95%CI[0.22,0.24]); ADR mainly occured in the reproductive, gastrointestinal, skin and accessories, blood, hepatobiliary system damage and the incidence of ADR in systems mentioned about respectively were 0.14(95%CI[0.12,0.17]),0.07(95%CI[0.06,0.08]),0.06(95%CI[0.04,0.07]),0.04(95%CI[0.03,0.05]),0.04(95%CI[0.03,0.05]). Further subgroup analysis results showed that the incidence of total ADR, especially the gastrointestinal, reproductive and cutaneous ADR of patients with treatment alone was higher than that in those paients with MTX or MTX+LEF therapy; The incidence of ADR, especially the gastrointestinal ADR, was also positively correlated with daily dose and course of treatment, while the incidence of different systems ADR was also correlated with different drug manufacturers, for instance, damage on the female reproductive system occurs most frequently in Hunan manufacture TGT administration, same as the damage on skin and accessories induced by TGT from Jiangsu manufacture. Above all, The clinical treatment of TGT for RA will cause multi-system ADR, with the highest incidence in the reproductive system, followed by the gastrointestinal system, which is closely related to the way of medication(monotherapy), daily dose, course of medication and drug manufacturer. Therefore, it is recommended that, in the treatment of RA, using TGT in combination, low dose or short-course medication, take measures to protect the reproductive system, stomach and liver, and paying attention to the drug manufacturer as well response of patients during administration should be valued to avoid ADRs to the maximum possibility.

Psychological distress is common in lung cancer patients with a poor prognosis. The present study aims to investigate the efficacy of collaborative care for patients with newly diagnosed inoperable lung cancer in South Korea. The study is a three-arm parallel-groups non-randomized clinical trial with an active arm that includes distressed patients who receive collaborative care, one comparison arm that includes distressed patients who receive enhanced usual care, and another comparison arm that includes non-distressed patients. In total, 267 consecutive patients newly diagnosed with medically inoperative lung cancer will be recruited. The primary outcomes are the changes in Hospital Anxiety and Depression Scale-depression and the Distress Thermometer at 12 and 32 weeks after enrollment. Sub-analyses of patients in the active arm of the study will include a comparison of the efficacy of a combination of oral antidepressant (escitalopram) treatment and collaborative care versus that of collaborative care alone.

STUDY DESIGN: A quasi-experimental single-blinded study. PURPOSE: To investigate the effects of ‘graded exercise integrated with education’ on physical fitness, exercise self-efficacy (ESE), and physical activity (PA) levels among subacute and chronic wheelchair-dependent paraplegia patients. OVERVIEW OF LITERATURE: Most of the chronic spinal cord injury (SCI) patients had low physical fitness due to a sedentary lifestyle and lack of ESE after discharge from a rehabilitation program. Education may encourage them to engage with exercise to regain and maintain their physical fitness. However, there is a lack of research to support the effects of exercise integrated with education after an SCI. METHODS: A total of 44 participants will be assigned to either the experimental group (graded exercise integrated with education) or active control (conventional physical therapy). The experimental group will receive graded strength and aerobic exercise training according to their progression criteria. They will attend an education program during and after the rehabilitation program. The control group will only receive conventional physical therapy during their in-rehabilitation program. This study will be conducted during a period of 16 weeks, consisting of 8 weeks of in-rehabilitation and 8 weeks post-rehabilitation. Statistical analysis will be performed using the IBM SPSS ver. 21.0 (IBM Corp., Armonk, NY, USA) at a significance level of p≤0.05. RESULTS: The primary outcome measures will be upper-limb isokinetic strength, isometric grip strength, and cardiorespiratory fitness. The secondary outcomes will be ESE and PA levels. CONCLUSIONS: An intervention that combines exercise training and education may be warranted to enhance the physical fitness, ESE, and PA levels in SCI patients. This trial was registered with ClinicalTrials.gov (NCT03420170).

PURPOSE: Optimal methods for communication skills training (CST) are an active research area, but the effects of CST on communication performance in objective structured clinical examinations (OSCEs) has not been closely studied. Student roleplay (RP) for CST is common, although volunteer simulated patient (SP) CST is cost-effective and provides authentic interactions. We assessed whether our volunteer SP CST program improved OSCE performance compared to our previous RP strategy. METHODS: We performed a retrospective, quasi-experimental study of 2 second-year medical student cohorts' OSCE data in Australia. The 2014 cohort received RP-only CST (N=182) while the 2016 cohort received SP-only CST (N=148). The t-test and analysis of variance were used to compare the total scores in 3 assessment domains: generic communication, clinical communication, and physical examination/procedural skills. RESULTS: The baseline characteristics of groups (scores on the Australian Tertiary Admission Rank, Undergraduate Medicine and Health Sciences Admission Test, and medicine program interviews) showed no significant differences between groups. For each domain, the SP-only CST group demonstrated superior OSCE outcomes, and the difference between cohorts was significant (P<0.01). The superiority of volunteer SP CST over student RP CST in terms of OSCE performance outcomes was found for generic communication, clinical communication, and physical examination/procedural skills. CONCLUSION: The better performance of the SP cohort in physical examination/procedural skills might be explained by the requirement for patient compliance and cooperation, facilitated by good generic communication skills. We recommend a volunteer SP program as an effective and efficient way to improve CST among junior medical students.

PURPOSE: To determine whether Lactobacillus reuteri DSM 17938 plays a role in absorption of iron preparations given to children with iron deficiency anemia (IDA). METHODS: We performed a quasi-experimental study involving pre- and postintervention tests using a control group in North Sulawesi province, Indonesia, between July and September 2017. We conducted a single-blind controlled trial that included primary school children who were diagnosed with IDA based on reticulocyte hemoglobin equivalent (Ret-He) levels <27.8 pg/L. RESULTS: A total of 66 children were randomized into 2 groups. Thirty-four children received iron preparations with the addition of L. reuteri DSM 17938 (group 1), whereas the other 32 received iron preparations alone (group 2). The baseline Ret-He levels before intervention were similar in both groups. After 14 days of intervention, mean Ret-He level in group 1 changed from 24.43±1.64 to 28.21±1.72 pg/L (P=0.000). Mean Ret-He level in group 2 changed from 24.31±1.42 to 27.03±2.14 pg/L (P=0.000). Statistical analysis showed a significant increase in Ret-He levels in both groups; Ret-He levels were significantly higher in the experimental group than in the control group (P<0.05). CONCLUSION: Children with IDA receiving iron preparations with L. reuteri DSM 17938 for 14 days show higher Ret-He levels than those receiving iron preparations alone.

PURPOSE: This study aimed to identify the effect of a situational module learning course on critical thinking disposition and metacognition in sophomore nursing students. METHODS: This study was a non-equivalent control-group pretest-posttest quasi-experimental design; the participants included 64 nursing students (32 in the experimental and 32 in the control group) from two Korean universities. Critical thinking disposition and metacognition between the control and intervention groups were measured before and after program participation. Data collection was conducted between September 1 and December 15, 2016. An independent t-test was used to determine differences in critical thinking disposition and metacognition between the groups and Pearson's correlations were measured for correlation with critical thinking disposition and metacognition. RESULTS: The intervention group showed higher critical thinking disposition (t=3.16, p=.002); intellectual integrity (t=2.85, p=.006); and open-mindedness (t=3.30, p=.002) relative to those of the control group. However, there were no statistical differences in metacognition between the two groups (t=−0.14, p=.888). A significant positive correlation between metacognition and critical thinking disposition was found. (r=.62, p<.001). CONCLUSION: The situational module learning course developed in this study could be used to promote critical thinking disposition in nursing students.

PURPOSE: The purpose of this study was to develop an informational leaflet on emergency care and to explore effects of facilitative nurse-patient interaction behavior using an informational leaflet on patient satisfaction with nurse-patient interaction behavior, patient anxiety, and patient satisfaction with use of emergency care. METHODS: This study was a quasi-experimental study that applied a nonequivalent control-group posttest-only design. The participants were 81 patients who visited the emergency department of a hospital in Korea; the experimental group (n=40) received facilitative nurse-patient interaction behavior using an informational leaflet, and the control group (n=41) received care under routine protocols without an information leaflet. The effects of the two groups were analyzed using an independent t-test with SPSS computer program. RESULTS: Patient satisfaction with nurse-patient interaction behavior and use of emergency care in the experimental group were significantly higher than in the control group. Patient anxiety related to using emergency care in the experimental group was significantly lower than the control group. CONCLUSION: Therefore, facilitative nurse-patient interaction behavior using an informational leaflet to the patient may be useful interventions that are easily implemented by nurses in emergency settings.

To explore the medication rules of herbal prescriptions for nonalcoholic fatty liver disease,and analyze the possible drug targets and interactions,in order to explore the mechanisms of the herbs. Randomized controlled trials of herbal prescriptions for treating nonalcoholic fatty liver disease were collected from CNKI,Wan Fang,VIP,Sino Med and PubMed databases. The properties,flavors and meridian tropism of herbs were analyzed by using systematic cluster analysis method with SPSS 19. 0 software. Subsequently,the association rules of herbs were analyzed by using Clementine 12. 0 software. Finally,the interactions between targets and relevant signaling pathways were analyzed by Traditional Chinese Medicine Systems Pharmacology Database(TCMSP),Search Tool for the Retrieval of Interacting Genes/Proteins(STRING) and Kyoto Encyclopedia of Genes and Genomes(KEGG). In the 88 prescriptions screened out,the commonly used herbs were Salvia miltiorrhiza,Bupleurum chinense,Alisma orientale,and Crataegus pinnatifida,and the potential signaling pathways were PPAR signaling pathway and calcium signaling pathway. The results showed that the main effects of herbal prescriptions were to improve blood flow/clear blood stasis,clear heatiness/dampness,promote digestion and strengthen spleen. And its mechanism of action may be achieved through the regulation of PPAR signaling pathway and calcium signaling pathway.
