Factors influencing the self-management of kidney transplant patients based on self-determination theory: a cross-sectional study.

Background: Self-determination theory is useful for explaining how kidney transplant recipients self-manage their postoperative health, including drug regimens, but few studies have applied this theory to transplant recipients. This study aimed to examine the influence of health professionals' autonomy support, autonomous motivation and competence on kidney transplant patients' self-management based on the self-determination theory. Methods: This study included 79 kidney transplant patients from one outpatient clinic in a general hospital in Seoul, Korea. Data on the health professionals' support of patient autonomy and the kidney transplant patients' autonomous motivation, competence, and self-management were collected from self-report questionnaires. Results: The factors that influenced self-management behavior in kidney transplant patients were competence (ß=0.377, P=0.001) and autonomous motivation (ß=0.293, P=0.006). The explanatory power of these variables was 30.1%. Conclusions: This study found that autonomous motivation and competence in kidney transplant patients affected their self-management, indicating that if healthcare professionals enhance patients' competence and autonomous motivation, their self-management can be improved. The development of intervention programs that assist healthcare professionals in strengthening patients' autonomous motivation and competence is recommended.

Pilot study of effective methods for measuring and stretching for pectoral muscle tightness in breast cancer patients.

[Purpose] To evaluate differences in pectoral muscle tightness according to arm abduction angle and to determine the best arm abduction angle for stretching of pectoral muscle tightness in breast cancer patients. [Subjects and Methods] Horizontal abduction differences of shoulders were measured bilaterally by arm abduction to 45°, 90°, and 135° to determine the best arm abduction angle for measuring pectoral muscle tightness. Thirty-two patients were divided into three pectoral muscle stretching groups (A: 45°, B: 90°, and C: 135°). We measured the shoulder range of motion, scores of the Disabilities of the Arm, Shoulder, and Hand, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and the Breast Module, and pain levels (using a visual analog scale) before and after therapy. [Results] The differences in degree of horizontal abduction between shoulders were significantly larger for arm abduction to 90° and 135° than that to 45°. Groups B and C showed greater improvements in horizontal abduction limitations than group A. [Conclusion] Horizontal abduction differences between shoulders are prominent when arms are abducted to 90° and 135°. The appropriate arm abduction angle for measuring horizontal abduction and effective stretching of pectoral muscle tightness may be >90°.

Assessment of peripheral neuropathy in patients with rheumatoid arthritis who complain of neurologic symptoms.

OBJECTIVE: To assess the prevalence of peripheral neuropathy in patients with rheumatoid arthritis (RA) having neuropathic symptoms, and to investigate the relationship between electrophysiological findings of peripheral neuropathy and clinical findings of RA. METHODS: Patients with a clinical diagnosis of RA and who had tingling or burning sensation in any extremity were electrophysiologically examined for evidence of peripheral neuropathy. Study parameters, including age, gender, laboratory parameters, duration of RA, and medication, were recorded. The symptoms and signs of neuropathy were quantified with the neuropathy symptom score, and the functional statuses of these patients were assessed. RESULTS: Out of a total of 30 RA patients, 10 (33%) had peripheral neuropathy: 2 had bilateral carpal tunnel syndrome (CTS), 5 had unilateral CTS, 1 had sensory polyneuropathy, and 2 had motor-sensory polyneuropathy. The mean ages of the patients with and without peripheral neuropathy were 69.4 and 56.5 years, respectively (p<0.05). A significant relationship was found between peripheral neuropathy and anti-cyclic citrullinated peptide (anti-CCP) antibody. However, no relationship was found between peripheral neuropathy and the type of medication, RA duration, the patients' functional status, neuropathic symptoms, erythrocyte sedimentation rate, and C-reactive protein values. CONCLUSION: Neuropathic symptoms are common in RA patients, and it is difficult to distinguish peripheral neuropathy symptoms from those of arthritis. Patients with RA, particularly elderly patients and anti-CCP antibody positive patients who complain of neuropathic symptoms should undergo electrophysiological examination.

Reliability and validity of the korean version of the pain disability questionnaire.

OBJECTIVE: To translate the English version of the Pain Disability Questionnaire (PDQ) into Korean and to investigate the reliability and validity of the Korean version of the PDQ (K-PDQ) in patients suffering chronic disabling musculoskeletal disorders (CDMDs). METHODS: The English version of the PDQ was translated into Korean. Ten patients with CDMDs were randomly selected for a pilot study to assess the comprehensibility of the pre-final version. One hundred and thirty-nine patients suffering from CDMDs for more than 3 months were enrolled in this study. Follow-up questionnaires were obtained to examine the test-retest reliability. Concurrent validity was evaluated by comparing the K-PDQ with the visual analogue scale (VAS). Construct validity was evaluated by comparing the K-PDQ with the brief form of the World Health Organization quality of life assessment instrument (WHOQOL-BREF) using Pearson correlation coefficient. Reliability was assessed using the intraclass correlation coefficient (ICC), and internal consistency was determined by Cronbach's alpha. RESULTS: Test-retest reliability was assessed in 70 patients, with an average time interval of 12 days. The ICC was 0.958 (p<0.001). Internal consistency reached Cronbach's alpha of 0.933 for the functional component and 0.870 for the psychosocial component. The correlation coefficient for the K-PDQ when compared with the VAS was 0.834 in the first assessment and 0.831 in the second assessment. All domains of the WHOQOL-BREF showed a significant negative correlation with the K-PDQ. CONCLUSION: The K-PDQ is a reliable and valid instrument for measuring disability and can be used to assess disability and treatment outcomes in Korean patients with CDMD.

High frequency of gross deletions in 5' LTR/gag and nef genes in patients infected with CRF02_AG of HIV type 1 who survived for over 20 years: an association with Korean red ginseng.

Abstract We have shown that Korean red ginseng (KRG) intake is associated with gross deletions in the 5' LTR/gag (gDeltaLTR/gag) and nef genes (gDeltanef) of patients infected with subtype B of HIV-1. Here, we investigated these effects in three long-term survivors (LTSs) of subtype CRF02_AG of HIV-1. The three LTSs were diagnosed with HIV in 1987, 1988, and 1989, and have been treated with KRG for 7-15 years. Thirty-two samples of peripheral blood mononuclear cells were obtained from the subjects and used to amplify the 5' LTR/gag and nef genes via nested PCR. We obtained 88 amplicons in 5' LTR/gag and 128 amplicons in nef. The frequency of gDeltaLTR/gag was significantly higher (37.5%) in three LTSs than in control patients (8.6%, p < 0.01). Eight amplicons (9.5%) contained premature stop codon(s) in the gDeltaLTR/gag in three LTSs. Fourteen of the 128 nef amplicons (10.9%) contained the gDeltanef, which was present in only two (7.7%) of the 26 amplicons from control subjects. Interestingly, gDeltanef was detected 7 years after the reinitiation of KRG intake in an LTS and, coincidently, CD4 T cell counts and CD4/CD8 ratios rapidly increased. These data indicate that long-term intake of KRG has the therapeutic potential to induce gross deletions in HIV-1.

[Health problems and psychosocial adaptation of children with cancer].

PURPOSE: The purpose of this study was to describe health problems and psychosocial adaptation in children with cancer and to determine the relationship between these two variables. METHOD: The data were collected from parents of 61 children with cancer, aged 4-11 years at one university hospital in Seoul. The instruments for this study were the Korea Child Behavior Check List (KCBCL) and a physical symptom checklist developed by the researchers. RESULT: The major health problems were coughing, sleeping disturbances, fatigue and weakness. The total behavior problem score for children in the cancer group was higher than the score for those in the norm group. The scores on the scales for withdrawal, somatic complaints, social immaturity, and internalizing problems were higher in the children with cancer compared to normative findings. Scores on social and school competence in the cancer group were lower than the norms for healthy children. The relationship between health problems and psychosocial adaptation was significant in the subscales of withdrawal, anxiety/depression, internalizing problems and social involvement in the off therapy group. CONCLUSIONS: This study shows the various areas that need further study in caring for children with cancer.
