Effects of Breastfeeding Empowerment Program on Breastfeeding Self-efficacy, Adaptation and Continuation in Primiparous Women

PURPOSE: The purpose of this study was to develop a breastfeeding empowerment program and to investigate the effects of the breastfeeding empowerment program on self-efficacy, adaptation and continuation of breastfeeding for primiparous women. METHODS: The 5 session breastfeeding empowerment program was developed and a non-equivalent control group non-synchronized quasi-experiment design was used. Fifty-five participants were assigned to either the experimental group (n=27) or the control group (n=28). Effects were tested using repeated measures ANOVA and χ²-test. RESULTS: Scores for self-efficacy, adaptation and continuation of breastfeeding of in the experimental group after program were significantly higher than 1 week, 4 weeks, 8 weeks scores in control group. CONCLUSION: The effects of the breastfeeding empowerment program for elevating self-efficacy, adaptation and continuation of breastfeeding in primiparous women were validated. Therefore, this program can be recommended for vigorous use in clinical practice.

Performance Characteristics of the UniCel DxI 800 Immunoassay for the Maternal Serum Quadruple Test, Including Median Values for Each Week of Gestation, in Korean Women / 대한진단검사의학회지

BACKGROUND: Maternal serum prenatal quadruple screening includes testing for alpha-fetoprotein (AFP), human chorionic gonadotrophin (hCG), unconjugated estriol (uE3), and dimeric inhibin A (DIA). We evaluated quadruple screening using an automated platform and looked for any ethnic differences in the median values of each marker. METHODS: We measured the concentrations of each quadruple test analyte using the UniCel DxI 800 system (Beckman Coulter, USA) in 788 Korean mid-trimester maternal serum samples and calculated their median values using Benetech software (Benetech, Canada). We also compared the results with those obtained using the Immulite 2000 assay (Siemens Healthcare Diagnostics, USA) or ELISA (DSL, USA) in 442 samples. RESULTS: We obtained mid-trimester median values for each marker. The following are the comparative results for each test using the Immulite 2000 assay or ELISA (x) and the UniCel DxI 800 immunoassay (y): AFP, y=1.10x+0.01, r=0.925; uE3, y=0.28x+0.24, r=0.885; hCG, y=1.22x-3047.8, r=0.944; and DIA, y=0.86x+15.31, r=0.833. Assay results for each of the four markers showed good correlations. However, significant biases necessitated new median calculations of prenatal risk estimates in all four tests. CONCLUSIONS: We established gestational age-specific second-trimester median values for four markers in Korean samples using the UniCel DxI 800 immunoassay system. Despite significant bias, there were good correlations between the results obtained using the UniCel DxI 800 immunoassay and those obtained using the Immulite 2000 assay.

Annual Report on External Quality Assessment in Therapeutic Drug Monitoring and Drug of Abuse in Korea (2009) / 임상검사와정도관리

We performed two trials of external quality assessment for Therapeutic Drug Monitoring (TDM) subcommittee of Korean Association of Quality Assurance for Clinical Laboratory (KAQACL) in 2009. The number of participating laboratories were 110, which is similar with that of previous 3 years. Average response rates were 97.8% in both trials, similar to those of previous years. Two kinds of control materials were requested to be tested in each trial so that each institution could find the possible systematic errors. The average drug item responded was 6.2 per institution, which was decreased slightly from 6.5 in recent 5 years. The most common test items were valproic acid, digoxin, carbamazepine, phenytoin, and theophylline which were peformed in more than 63.8% of participating laboratories, followed by phenobarbital, cyclosporine, tacrolimus, vancomycin, lithium, methotrexate, amikacin, gentamicin, acetaminophen, tobramycin, salicylate, free phenytoin, amitryptyline, ethosuximide, and primidone. The widely used TDM analyzers were Abbott AxSym (26.9%), followed by Abbott TDx/TDxFLx (24.8%), Roche Cobas Integra (15.1%), Siemens Diagnostics Viva-E (5.5%), Roche cobas c501 (5.1%), Siemens Diagnostics Dimension (3.4%), and many other analyzers. The inter-laboratory coefficients of variations showed similar tendency comparing with those of the previous years. The number of participating laboratories for drug of abuse (DOA) tests were 19, which was slightly increased compared to that of the previous year. Average DOA items were 3.8~4.2. We found the good performance of participating laboratories for DOA. In conclusion, the TDM and DOA external quality assessment of 2009 showed similar performance comparing with that of the recent 3 years.

Annual Report on 2008 External Quality Assessment in Therapeutic Drug Monitoring and Drug of Abuse in Korea (2008) / 임상검사와정도관리

Two trials of external quality assessment for Therapeutic Drug Monitoring (TDM) subcommittee of Korean Association of Quality Assurance for Clinical Laboratory (KAQACL) were performed in 2008. The number of participating laboratories were 114, which is similar with that of the previous year. Average response rates were 97.8% in both trials slightly lower than that of the previous year. Two kinds of control materials were requested to be tested in each trial so that each laboratory could know the possible systematic error. The average drug item was 6.3 per laboratory, which was decreased slightly from 6.8 in recent 5 years, and the maximum was 18 items. The most common test items were valproic acid, digoxin, carbamazepine, theophylline, phenytoin, and phenobarbital which were peformed in more than 52.1% of participating laboratories, followed by cyclosporine, vancomycin, tacrolimus, lithium, methotrexate, amikacin, tobramycin, gentamycin, acetaminophen, salicylate, free phenytoin, primidone, and amitryptyline. The widely used TDM analyzers were Abbott TDx/TDxFLx (35.3%), followed by Abbott AxSym (26.5%) and Roche Cobas Integra (17.3%), Abbott IMx (3.3%), and Siemens Viva E (3.0%). The inter-laboratory coefficients of variations showed similar tendency comparing with those of the previous years. The number of participating laboratories for drug of abuse tests were 17, which is similar to that of the previous year. Average drug item were 3.7 for the 1st trial. We found the relatively good performance as we got the correct answers for all laboratories except 2 laboratories. In conclusion, the TDM external quality assessment of 2008 showed grossly similar pattern comparing with that of previous year.

Development of a Cognitive Rehabilitation Program for Patients with Schizophrena / 신경정신의학

OBJECTS: The purpose of this study was to investigate the effects of cognitive differentiation training program-Korean version(a training program of attention and conceptual abilities) on cognitive function, psychopathology and problem solving skills in patients with schizophrenia. METHODS: A total of patients diagnosed as schizophrenia using DSM-IV were randomly assigned to 2 groups. The training group went through a total of 22 sessions of cognitive differentiation training (60min/sessionX2sessions/wkX11wks). The attention-placebo control group received psychoeducation program during the same period. Arithmetic, vocabulary, similarities, picture completion of Wechsler Adult Intelligence Scale-Korean version, Positive and Negative Syndrome Scale, and Social Problem Solving Scales were administered to all patients, both before and after the training program. RESULTS: In the arithmetic scores(F=6.35, af=1, p=0.018) of Wechsler Adult Intelligence Scale-Korean version, and total scores(F=6.35, af=1, p=0.018) and problem solving skill scale scores (F=4.88, af=1, p=0.036) of social problem solving scale, interaction effects of training was significant. CONCLUSION: Our findings suggest that cognitive differentiation training program-Korean version is effective on improving auditory attention and problem solving skills in patients with schizophrenia.

Effects of Integrated Psychological Therapy for Schizophrenic Patients / 신경정신의학

OBJECTIVES: This study, as a preliminary one attempting to develop the Korean version of Integrated Therapy for the rehabilitation of schizophrenic patients, was designed to investigate the results of Integrated Psychological Therapy(IPT) and review the problems during the program application. METHODS: Cognitive Differentiation Scale, Problem-Solving Scale, and PANSS(Positive And Negative Syndrome Scale) were administered to schizophrenic inpatients before and after IPT incorporating cognitive differentiation, social perception, verbal communication, social skill and interpersonal problem-solving skill subprograms. The therapy groups were offered activities three times per week during the 12-week program. The control groups were attention-placebo groups for control ling factors such as group interaction and social attention, and were offered psychoeducation. RESULTS: The 12-week IPT groups, compared with the control groups, demonstrated significant improvements in the general psychopathology and the total symptoms of PANSS, but did not in cognitive functions and problem-solving skill. Significant improvements in cognitive functions were found only after cognitive differentiation subprogram and social skill subprogram had limited effects on social skills. But within 12-week IPT groups significant improvements in the positive symptoms, negative symptoms and general psychopathology were found. CONCLUSION: These findings support some effectiveness of IPT, but do not address the unique contribution by cognitive components. Applied to schizophrenic patients in this country, this modality had the problems such as differences in sociocultural and lingual background, duration of treatment, homogeneity in the level of the functioning among group members, management of emotions in activities, and the therapists' skill in the training of cognitive components. So the modification of this modality will be required.
