  • Background: There is an increasing concern in the role of microRNA (miRNA) in the pathogenesis of bone metastasis (BM) secondary to prostate cancer (CaP). In this exploratory study, we hypothesized that the expression of vinculin (VCL) and chemokine X3C ligand 1 (CX3CL1) might be down-regulated in clinical samples, most likely due to the post-transcriptional modification by microRNAs. Targeted genes would be up-regulated upon transfection of the bone metastatic prostate cancer cell line, PC3, with specific microRNA inhibitors. Materials and Methods: MicroRNA software predicted that miR-21 targets VCL while miR-29a targets CX3CL1. Twenty benign prostatic hyperplasia (BPH) and 16 high grade CaP formalin-fixed paraffin embedded (FFPE) specimens were analysed. From the bone scan results, high grade CaP samples were further classified into CaP with no BM and CaP with BM. Transient transfection with respective microRNA inhibitors was done in both RWPE-1 (normal) and PC3 cell lines. QPCR was performed in all FFPE samples and transfected cell lines to measure VCL and CX3CL1 levels. Results: QPCR confirmed that VCL messenger RNA (mRNA) was significantly down-regulated while CX3CL1 was up-regulated in all FFPE specimens. Transient transfection with microRNA inhibitors in PC3 cells followed by qPCR of the targeted genes showed that VCL mRNA was significantly upregulated while CX3CL1 mRNA was significantly down-regulated compared to the RWPE-1 case. Conclusions: The down-regulation of VCL in FFPE specimens is most likely regulated by miR-21 based on the in vitro evidence but the exact mechanism of how miR-21 can regulate VCL is unclear. Up-regulated in CaP, CX3CL1 was found not regulated by miR-29a. More microRNA screening is required to understand the regulation of this chemokine in CaP with bone metastasis. Understanding miRNA-mRNA interactions may provide additional knowledge for individualized study of cancers.

  • X-linked agammaglobulinemia (XLA) is a hereditary humoral immunodeficiency that results from Bruton's tyrosine kinase (BTK ) gene mutations. These mutations cause defects in B-cell development, resulting in the virtual absence of these lymphocytes from the peripheral circulation. Consequently, this absence leads to a profound deficiency of lg all isotypes, and an increased susceptibility to encapsulated bacterial infections. A 15-month-old Korean boy presented with recurrent sinusitis and otitis media after 6 months of age, and had a family history of 2 maternal uncles with XLA. Laboratory tests revealed a profound deficiency of Ig isotypes, and a decreased count of $CD19^+$ B cells in the peripheral circulation. Based on his family history and our laboratory test results, he was diagnosed with XLA. We performed BTK gene analysis of peripheral blood samples obtained from family members to confirm the diagnosis. Mutational analysis revealed a novel hemizygous frameshift mutation (c.82delC, p.Arg28Alafs*5), in the BTK gene. His mother and maternal grandmother were heterozygous carriers of this mutation and his two maternal uncles were hemizygous at the same position. After XLA diagnosis, intravenous immunoglobulin (400 mg/kg, monthly) treatment was initiated; recurrent sinusitis and otitis media were subsequently brought under control. To our knowledge, this is the first reported case of a Korean pedigree with a novel mutation in the BTK gene.

  • Introduction: Breast cancer is the most common cancer among Jordanians. Breast cancer patients suffer from several negative consequences after treatment and these include pain, fatigue, sexual problems, appearance and body image concerns, with psychological dysfunction. This could affect the patient quality of life and psychological well-being. To the best of our knowledge, there is no published quantitative data on the quality of life and psychological well-being of breast cancer patients in Jordan. The objective of this study was to obtain such data and assess predictors with calculated scores. Methods: In this cross-sectional study conducted among breast cancer patients in Jordan diagnosed in 2009 and 2010, assessment was performed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Breast Module (QLQ-BR23) and the Hospital Anxiety and Depression Scale (HADS). Clinical, demographic and psychosocial indicators that could predict patient quality of life scores were collected. Results: The number of patients interviewed was 236 (mean age=$50.7{\pm}10.7$ years). The mean Global Health score for the QLQ-C30 was $63.7{\pm}20.2$ SD. Among functional scales, "social functioning" scored the highest ($mean=78.1{\pm}28.6$ SD), whereas "emotional functioning" scored the lowest ($mean=59.0{\pm}SD\;33.5$). For the QLQ-BR23, the worst scores within the functional scales were for "body image" ($mean=52.1{\pm}36.8$ SD) and "future perspective" ($mean=52.9{\pm}38.5$ SD). The worst symptom was "upset by hair loss" ($mean=69.8{\pm}43.0$). The mean HADS scores was $18.{\pm}9.0$ SD. Out of study participants, 53% scored abnormal on the anxiety scale and 45% on the depression scale. Severe depression and severe anxiety were detected among 8% and 14% of study participants, respectively. Statistically significant predictors for individual scores were similar to those reported in published studies, such as the presence of recurrence since baseline, family history of cancer, low educational status, current social problems, extent of the disease, presence of financial difficulties, and employment status. Conclusions and Recommendations: Breast cancer survivors in Jordan have overall good quality of life scores when compared with patients from Western countries. However, their psychological wellbeing is more impaired. There is an urgent need for psychosocial support programs and psychological screening and consultation for breast cancer patients at hospitals of the Ministry of Health in Jordan.

  • Objectives: This study was conducted to examine the preferences and needs of typical Korean females adults for food and nutrition information provided by the mass media. Methods: A total of 343 females (77 in their 20s, 85 in their 30s, 88 in their 40s and 93 in their 50s) residing in the Seoul/Gyeonggido area was surveyed on general characteristics, main sources of food and nutrition information and needs for sources and contents of nutrition information. Results: The survey showed that typical Korean females obtained knowledge of food and nutrition mainly through the Internet (30.4%) and broadcasting (29.0%). Typical Korean females were interested in 'dietary management for weight control' (21.9%), 'the prevention and treatment of disease' (20.0%), 'food safety' (16.8%), 'proper dietary habits' (14.6%), 'cookery' (11.8%), 'functional foods' (9.6%), 'restaurant details' (3.5%) and 'life-cycle-specific dietary guideline' (1.6%). Needs for food and nutrition program forms on TV were 'educational programs' (34.3%), 'documentaries' (20.8), 'expert lecture-style' (13.0%), 'entertainment programs' (11.9%), 'expert conversation' (11.4%), 'news-style' (4.6%) and 'public campaign advertisements' (4.0%). On the Internet, 38.6% of the respondents preferred to get information provided by food and nutrition-related institutions (38.6%) while 26.1% preferred webtoons for nutritional information. The favored forms in mobile applications were 'monitoring their diets' (29.5%), 'data-based texts information' (21.4%), 'experts feedback' (20.6%), 'communities' (15.1%) and 'games' (13.1%). The rates of the preference to obtain information from experts such as nutritionists and dietitians and doctorsor dietitian turned reporters increased markedly with older ages. Conclusions: Since the mass media is a main source of food and nutrition information for the general public, the effectiveness and accuracy of the information provided should be enhanced by taking the needs of the public into account. The quality of information should be improved by involving more nutrition experts.

  • This study was focused on figure out what kinds of elements are influencing on job satisfaction with approach of the educational system. It was also to figure out how work characteristics and role conflicts of employees influence on job satisfaction. Objects of study were employeeswho had been working in Hospice and Palliative medical center at least for 6 months, and they were doctors, nurses, ministers, and welfare workers. Collected materials were analyzed by Frequency Analysis, One-way ANOVA, Correlation Analysis, and SimpleRegression Analysis. Results from study can be summarized like below. The first, job satisfaction of workers in Hospice and Palliative medical center were 3.36, and this numerical value is pretty high over all. For saying from the higher to the lower satisfaction level, there were satisfaction with job itself, satisfaction with co-workers, satisfaction with seniors (superiors), and satisfaction with organizations, on the other hands, satisfaction with salaries was turned out as the lowest level among those. The second, role conflict was 2.63, and it is considered as the medium level. after inquiring into it by elements of role conflict, they felt many environmental difficulties compared to other workers in different fields such as environmental difficulty, role ambiguity, insufficient ability, process obscurity, etc. The third, work environment influencing on job satisfaction are as follows. Professional environment among characteristics of work environment was significant statistically. Job satisfaction of ministers was the highest; others were in the order of doctors, welfare workers, and nurses. For employment history, job satisfaction was higher as they have more and longer job experience including whole professional experience both in hospice and palliative medical center. In addition, participating in hospice and palliative programs, intensive training regularly was significantly. Job Motivation was also significant statistically. Especially, job satisfaction was higher when people decided to work in hospice and palliative medical center because of individual desire (self-realization). Lastly, influence of role conflict on job satisfaction is as follows. Environmental difficulty, role ambiguity, insufficient ability, process obscurity, etc showed the significant meaning statistically, and the lower role conflict was related with the higher job satisfaction. Suggestions for next study based on such results are as follows in order to improve or increase job satisfaction of employees in hospice/palliative medical centers. The first, to expand education opportunity of employees is needed to increase job satisfactionof hospice/palliatives medical centers. Participating in intensive programs and seminars by types of occupation and acquiring professional knowledge are very important since employees are motivated by those activities. For that, developing and activating intensive education/programs by professional occupations are suggested. The second, dividing roles of employees and determining each job's limit clearly in hospice/palliative medical centers are required. For that, study developing standard job regulations is suggested for each professional job. Lastly, developing and providing reasonable salaries is needed because low salaries of hospice/palliative medical centers are the absolute reason lowering job satisfaction. Therefore, this paper suggests improving the salary level of employees of hospice/palliative medical centers and developing practical plan for it.
