  • Introduction: Although most prostate cancers initially respond to castration with luteinizing hormonereleasing analogues or bilateral orchiectomy, progression eventually occurs. Based on the exciting results of several randomized controlled trials (RCTs), it seems that patients with metastatic castration-resistant prostate cancer (mCRPC) might benefit more from treatment withabiraterone. Therefore we conducted a systematic review to evaluate the efficacy and toxicity of abiraterone in the treatment of mCRPC. Methods: Literature was searched from Embase, PubMed, Web of Science, and Cochrane Library up to July, 2013. Quality of the study was evaluated according to the Cochrane's risk of bias of randomized controlled trial (RCT) tool, then the Grading of Recommendations Assessment, Development and Evaluation (GRADE) System was used to rate the level of evidence. Stata 12.0 was used for statistical analysis. Summary data from RCTs comparing abiraterone plus prednisone versus placebo plus prednisone for mCRPC were meta-analyzed. Pooled hazard ratios (HRs) for overall survival (OS), radiographic progression-free survival (RPFS) and time to PSA progression (TTPP); Pooled risk ratios (RR) for PSA response rate, objective response rate and adverse event were calculated. Results: Ten trials were included in the systematic review; Data of 2,283 patients (1,343 abiraterone; 940 placebo) from two phase 3 trials: COU-AA-301 and COU-AA-302 were meta-analyzed. Compared with placebo, abiraterone significantly prolonged OS (HR, 0.74; 95% confidence interval [CI], 0.66 to 0.84), RPFS (HR, 0.59; 95% CI, 0.48 to 0.74) and time to PSA progression (HR, 0.55; 95% CI, 0.43 to 0.70); it also significantly increased PSA response rate (RR, 3.63; 95% CI, 1.72 to 7.65) and objective response rate (RR, 3.05; 95% CI, 1.51 to 6.15). This meta-analysis suggested that the adverse events caused by abiraterone are acceptable and can be controlled. Conclutios: Abiraterone significantly prolonged OS, RPFS and time to progression patients with mCRPC, regardless of prior chemotherapy or whether chemotherapy-na$\ddot{i}$ve, and no unexpected toxicity was evident. Abiraterone can serve as a new standard therapy for mCRPC.

  • Background: As a common and essential contrast medium at present, gadobenate dimeglumine has shown better performance than some other agents when applied to Breast Magnetic Resonance Imaging Screening (Breast MRI Screening). Nevertheless, reports on the diagnostic performance of these two mediums (gadobenate dimeglumine and gadopentetate dimeglumine) are not completely consistent. Objective: To assess the diagnostic value of gadobenate dimeglumine and gadopentetate dimeglumine for Breast MRI Screening in patients suffering from breast cancer and to provide more convinced evidence to guide clinical practice in terms of appropriate contrast agents. Data Sources and Review Methods: Original articles in English and Chinese published before January 2013 were selected from available databases (The Cochrane Library, PUBMED, EMBASE, Chinese Biomedical Literature Database, Chinese Scientific Journals Full-text Database, Chinese Journal Full-text). The criteria for inclusion and exclusion were based on the standard for diagnosis tests. Meta-Disc software (Version 1.4) was used for data analysis. Then, the area under curve (AUC) of SROC and the spearman rank correlation of sensitivity against (1-specificity) were calculated. Results: Total of 17 researches involving 1934 patients were included. The pooled sensitivity of gadobenate dimeglumine and gadopentetate dimeglumine were 0.99 (0.97, 1.00) and 0.93 (0.88, 1.00) respectively. The pooled specificity for these two contrast agents were 0.924 (0.902, 0.943) and 0.838 (0.817, 0.858) respectively, and the AUC of SROC curve were 0.9781 and 0.9215 respectively. Conclusions: Gadobenate dimeglumine can be regarded as a more effective and feasible contrast medium for Breast MRI Screening. At least 5% differences in diagnostic performance are usually considered as clinically relevant.

  • The purpose of this study was to identify the effects of non-pharmacological interventions for Korean adults with insomnia. Literature review was performed for articles published between 2000 and 2016 in electronic databases. Sixteen articles met the inclusion criteria. Data were analyzed by R version 3.3.1 for windows. Meta-analysis was performed using the random effects model; the overall effect size of non-pharmacological interventions on sleep was significantly large (Hedges' g=2.36, 95% CI: 1.44~3.28). For heterogeneity, a moderator analysis was performed using the study design, participants, age group, intervention, presence of hospitalization, and sleep measurement. There was a statistically significant difference between the effects of moderator variables, except for the study design and participants. Of the interventions, auricular acupressure reported to have the largest effect size on sleep. The findings in this study indicate that non-pharmacological interventions have a positive effect on sleep, providing objective evidence to improve sleep in adults with insomnia using effective interventions.

  • This study was a systematic review examining the effect of empowerment intervention studies among patients with chronic physical health conditions in Korea. The PICOT-SD (Participants, Intervention, Comparison, Outcomes, Timing of outcome measurement, Setting, Study design) strategy was applied. A total of 19 studies published between January 2000 and April 2020 were selected. Study participants were rheumatoid arthritis patients, hemodialysis patients, stroke patients, diabetes mellitus patients, chronic pulmonary disease patients, hypertensive patients, cancer patients, chronic kidney disease patients, and kidney transplantation patients, etc. A total of 17 studies were found to have presented a conceptual framework. Empowerment skills were participation, dialogue, experience, interaction, support, and problem solving, etc. The most frequently used dependent variables were self-care (n=13), empowerment (n=10), self-efficacy (n=7), and depression (n=5). Self-care, empowerment, and self-efficacy showed significant improvement among patients in at least 60% of the included studies. Based upon this review, there is evidence that empowerment intervention studies are an effective method to improve the health of patients with chronic physical health conditions. This study further suggests the development of an empowerment intervention program to verify the effects of the various variables identified in this study.

  • Developing our understanding of retail employee job satisfaction is important, especially given its impact in reducing employee turnover intentions and increasing employee job performance. While developing our understanding of job satisfaction is important, the vast majority of studies examine job satisfaction as a global or single-faceted construct. However, extant research provides evidence that to properly measure job satisfaction, multi-faceted scales are required (e.g. Churchill et al., 1974; Boles et al., 2007; Rutherford et al., 2009). Using the literature on multi-faceted job satisfaction, this study examines retail employees' satisfaction with supervision, job, company policy, promotion, pay, fellow workers, and customers. Specifically, emotional exhaustion, need for emotion, and personal traits (strong, independent, and warm) are examined as antecedents. This study finds that emotional exhaustion is negatively related to all seven facets of job satisfaction.

  • Background: Hominis placenta (HP) is used in Korean medicine to tonify qi and blood, and enrich yin and tonify yang. HP has been reported to have therapeutic effects. Methods: A survey of international and Korean electronic databases was conducted using the search terms "hominis placenta pharmacopuncture" and "hominis placenta extract". The search was limited to material published up to May 31, 2017. Results: A total of 83 studies were included in this systematic review: 50 were clinical studies, 25 were basic studies, and 8 were other types of study. Among clinical studies, the most frequently treated disease groups were musculoskeletal diseases and nervous system diseases. In vitro studies were conducted mainly on anti-inflammatory, analgesic, and anti-cell necrosis models. Most of the in vivo studies were performed in rheumatoid arthritis or diabetic complications models. Conclusion: HP pharmacopuncture has effects in the treatment of various diseases. Further large-scale randomized controlled trials are needed to improve the level of evidence for HP pharmacopuncture. It would be helpful if future in vitro and in vivo studies could identify the mechanism of action of HP pharmacopuncture.

  • Background: Advancements in the field of microvascular surgery and the widespread adoption of microvascular surgical techniques have made the use of osteocutaneous fibula free flaps the standard of care in the surgical management of segmental mandibular defects. Although the literature possesses abundant evidence to support the effectiveness of fibula free flaps as a reconstructive method, there are relatively few studies reporting on outcomes as objectively measured by videofluoroscopic swallowing studies (VFSS). The purpose of this study is to explore the potential correlation between early postoperative VFSS and the long-term swallowing outcomes in patients who underwent mandibular reconstruction with fibula free flaps. Methods: We performed a retrospective chart review of 36 patients who underwent mandibular reconstruction with osteocutaneous fibular free flaps between 2009 and 2012. Demographics, clinical variables, VFSS data, and diet information were retrieved. Penetration and aspiration findings on VFSS, long-term oral feeding ability, and the need for gastrostomy tube were statistical endpoints correlated with postoperative clinical outcomes. Results: Thirty-six patients were reviewed (15 females and 21 males) with a mean age of 54 years (7-81). Seventeen cases were treated for malignancy. The size of the bony defect ranged from 3 to 15 cm (mean = 9 cm). The cutaneous paddle, a surrogate for soft tissue defect, ranged from 10 to 125 ㎠ (mean = 52 ㎠). A gastrostomy tube was present in patients preoperatively (n = 8), and postoperatively (n = 14). Seventeen patients had neoadjuvant exposure to radiation. Postoperative VFSS showed penetration in 13 cases (36%) and aspiration in seven (19%). Overall, 29 patients (80.6%) achieved unrestricted diet, and this was statistically correlated with age (p = 0.037), radiation therapy (p = 0.002), and preoperative gastrostomy tube (p = 0.03). The presence of penetration or aspiration on VFSS was a strong predictor for long-term unrestricted oral diet (p < 0.001). Conclusion: Early postoperative VFSS is an excellent predictor for long-term swallowing outcomes in patients undergoing mandibular reconstruction with osteocutaneous fibula free flaps.

  • Objectives This study aimed to review manual therapies for mononeuropathies of upper limb through domestic and foreign studies designed for human body. Methods We searched databases (KMbase, OASIS, RISS, NDSL, KISS, KoreaMed, MEDLINE/Pubmed, CENTRAL, EMBASE) on the 1st to 31th of July 2017 to find related literatures that published after 2000. Results Twenty-eight studies were finally included. Of these, 13 articles were published after 2010. Twenty-two studies were clinical trials and 6 were observational studies. Carpal tunnel syndrome were the most researched type of diseases (85.7%). Most frequently used method of manual therapies was neurodynamic mobilization (35.7%). Pain scales and questionnaires were generally employed for evaluation. Significantly effective studies were 72.2% in controlled trials and 90% in the studies without control group. Conclusions In this study, we reviewed literatures concerning manual therapies on mononeuropathies of upper limb. Further studies are needed on the various diseases of mononeuropathies of upper limb to retain the evidence for the effectiveness of manual therapies.

  • Background: Repeating a prior chemotherapy (rechallenge therapy) is an option for selected patients with metastatic colorectal cancer, but there is very little evidence in the literature for this approach. Thus, we reviewed our registry to evaluate prognostic factors and survival of patients who received irinotecan and oxaliplatin-based regimens as rechallenge third and fourth-line therapy. Materials and Methods: Patients who received irinotecan-based or oxaliplatin-base regimen as first-line had been rechallenged with third-line or fourth-line therapy. These patients were selected from the database of Turkish mCRC registry archives between October 2006 and June 2013 and evaluated retrospectively for factors effecting progression free survival (PFS) and overall survival (OS) by the Kaplan-Meire and Cox-regression methods. Results: Thirty-nine patients were enrolled. The median duration of follow-up was 36 months (14-68 months). Thirty-one patients (76%) died during follow-up. In terms of rechallenge treatments, 29 patients had received third-line and 10 patients had received fourth-line. Response rate (RR) was found to be 12.9%, with stable disease in 19 (48.7%) patients. The median PFS was 6 months (95%CI=4.64-7.35 months) and the median OS was 11 months (95%CI=8.31-13.68 months). The factors effecting survival (PFS and OS) were only being PFS after first-line chemotherapy ${\geq}12months$ (p=0.007, 95% CI=1.75-35.22 and p=0.004, 95%CI=1.44-7.11), both in univariate and multivariate analyses. Conclusions: This study indicates that rechallenge treatment could be a good option as a third or later line therapy in patients who had ${\geq}12months$ PFS onreceiving first line therapy.

  • Pregnancy is a task of creation in which a women mobilizes her self and the resources available to her in the generation of a new person. Through the pregnancy, a mother has formed the new human relationship with a fetus. Maternal-fetal relationship is considered one of mechanism making the relationship of mother and child. It is important to well-being of mother and fetus, too. The earliest interaction between a mother and her child is during prenatal period. Maternal-fetal dyad is unique and perceived interactions with the fetus make the pregnancy real for the mother. Maternal behavior is "instinctive" and is formed in early childhood by copy of the mother. But, Rubin argues that this behavior is an open intellectual system rather than a prepackaged bundle of traits. There is openness to new learning and a high value placed on knowing which occurs with silent organization in thought. Thus, nurses and other health professionals provide prenatal care that optimally is part of the environment in which the maternal-fetal dyad develops. Thus it is appropriate for nurses to increases their understanding of the dyad and to explore ways to enhance its development. This study focusses on the interaction ability and response of fetus, and the maternal-fetal interaction. The research of fetal responses that involve physiological changes and motor movement have been shown to coccur to both external sensory stimuli and to maternal emotional states. The fetus does also have sensory capacity to be aware of some maternal behaviors, and the motor ability to respond in a way the mother can notice. Thus, very rudimentary interactions appear to be possible. Maternal awareness of fetal activity was supported by several studies. More interesting to the present study are description of maternal-fetal interaction and the finding that there appear to be levels of sensitivity to the fetus involved in maternal-fetal interactions. First, recognition comes that the fetus is separate from the maternal self. Next, the fetus engages in. Lastly, the parent may describe active interaction with the fetus, believing that mother and fetus are communicating on a meaningful level. Several interventions, developed to promote more active interaction between mother and fetus, have been reviewed. In general, the parents were taught to stimulate the fetus and to notice the fetus' responses. This type of intervention might increase the mother's sensitivity to her unborn baby, and she may have a head start toward learning how to res pond sensitivity to the newborn infant. Research In the area of maternal-fetal interaction is scarce. Sensitive behavior is construed as an appropriate and timely response to a signal of need from another person, but no such signal of need can be claimed regarding the fetus. The highest level of maternal-fetal interaction, therefore, might be based more on maternal representations of the imagined fetus than on factual evidence of fetal participation.
