Emotional autonomy and perceived parenting styles: relational analysis in the Hong Kong cultural context

Kwok Wai Chan 서울대학교 교육연구소 2009 Asia Pacific Education Review Vol.10 No.4

Three hundred and seven teacher education students of a Hong Kong university were administered two questionnaires, one measuring emotional autonomy (EAS) and the other measuring perceived parenting styles (PAQ) of their parents. It was found that the Hong Kong teacher education students tended to be autonomous and they characterized their parents as authoritative instead of authoritarian. In addition, the emotional autonomy scale was positively related to authoritarianism, but negatively related to authoritativeness and permissiveness of parenting. Emotional detachment instead of autonomy seemed to be a more appropriate meaning of EAS for the interpretation of results. Implications were drawn for future research including development of an improved instrument in measuring emotional autonomy to study its associations with perceived parenting styles of young people across cultures.

Total knee arthroplasty (TKA) is associated with significant perioperative blood loss and postoperative allogenic blood transfusion. Tranexamic acid (TXA) reversibly blocks lysine binding sites on plasminogen molecules and inhibits plasmin formation. Comparisons of the efficacy and safety of intra-articular and intravenous TXA in primary TKA have not previously been reported.A prospective randomized trial was conducted in 150 patients who underwent TKA, and these patients were randomized into three groups. Patients in Group A were injected by intra-articular TXA according to body weight (20 mg/kg). Patients in Group B received a standard dose of intra-articular TXA (2000 mg), and those in Group C were infused with TXA according to body weight (20 mg/kg) before tourniquet deflation and again 3 h later. Baseline characteristics and data collected at blood transfusion were compared. Differences among four time points (baseline, day 0, day 2, and day 5) were carried out using ANOVA. The hemoglobin levels at postoperative day 5 were 10.6 g/dL for Group A, 10.6 g/dL for Group B, and 10.7 g/dL for Group C. The drain output was 399 ml for Group A, 314 ml for Group B, and 305 ml for Group C ( p = 0.03). Group C had significantly less drain output than Group A after post hoc comparisons ( p = 0.05), whereas no significant difference was observed between Group A and B ( p = 0.09) or between Group B and C. The weight-adjusted dose of TXA administered intravenously significantly reduced the drain output but not the total blood loss when compared with the weight-adjusted dose of TXA administered intra-articularly. No significant difference was observed in the other parameters among the three groups. The Joint CUHK-NTEC CREC, CRE-2013.644-T . Registered 1 March 2014.

Wai Kwong Tang,Lisha Wang,George Kwok Chu Wong,Gabor S. Ungvari,Fumihiko Yasuno,Kelvin K.F. Tsoi,Jong S. Kim 대한뇌졸중학회 2020 Journal of stroke Vol.22 No.1

Background and Purpose Depression is common and debilitating illness accompanying many neurological disorders including non-traumatic subarachnoid hemorrhage (SAH). The aim of this systematic review was to identify and critically appraise all published studies that have reported the frequency, severity and time course of depression after SAH, the factors associated with its development and the impact of depression on patients’ quality of life after SAH. Methods The PubMed database was searched for studies published in English that recruited at least 40 patients (>18 years old) after SAH who were also diagnosed with depression. Results Altogether 55 studies covering 6,327 patients met study entry criteria. The frequency of depression ranged from 0% to 61.7%, with a weighted proportion of 28.1%. Depression remained common even several years after the index SAH. Depression after SAH was associated with female sex, premorbid depression, anxiety, substance use disorders or any psychiatric disorders, and coping styles. Comorbid cognitive impairment, fatigue, and physical disability also increased the risk of depression. Aneurysmal SAH and infarction may be related to depression as well. Depression reduces the quality of life and life satisfaction in patients after SAH. Conclusions Depression is common after SAH and seems to persist. Further research is needed to clarify its time course and identify the neuroendocrine and neurochemical factors and brain circuits associated with the development of post-SAH depression. Randomized controlled treatment trials targeting SAH-related depression are warranted.

Korean Red Ginseng extract induces angiogenesis through activation of glucocorticoid receptor

Wai-Nam Sung,Hoi-Hin Kwok,Man-Hee Rhee,Patrick Ying-Kit Yue,Ricky Ngok-Shun Wong 고려인삼학회 2017 Journal of Ginseng Research Vol.41 No.4

Background: Our previous studies have demonstrated that ginsenoside-Rg1 can promote angiogenesis in vitro and in vivo through activation of the glucocorticoid receptor (GR). Furthermore, microRNA(miRNA) expression profiling has shown that Rg1 can modulate the expression of a subset of miRNAs to induce angiogenesis. Moreover, Rb1 was shown to be antiangiogenic through activation of a different pathway. These studies highlight the important functions of miRNAs on ginseng-regulated physiological processes. The aim of this study was to determine the angiogenic properties of Korean Red Ginseng extract (KGE). Methods and Results: Combining in vitro and in vivo data, KGE at 500 mg/mL was found to induce angiogenesis. According to the miRNA sequencing, 484 differentially expressed miRNAs were found to be affected by KGE. Among them, angiogenic-related miRNAs; miR-15b, -23a, -214, and -377 were suppressed by KGE. Meanwhile, their corresponding angiogenic proteins were stimulated, including vascular endothelial growth factor, vascular endothelial growth factor receptor-2, endothelial nitric oxide synthase, and MET transmembrane tyrosine kinase. The miRNAs-regulated signaling pathways of KGE were then found by Cignal 45-Pathway Reporter Array, proving that KGE could activate GR. Conclusion: KGE was found capable of inducing angiogenesis both in vivo and in vitro models through activating GR. This study provides a valuable insight into the angiogenic mechanisms depicted by KGE in relation to specific miRNAs.

Does Aging Matter? The Efficacy of Carpal Tunnel Release in the Elderly

Bettina Wai Yan Fung,Chris Yuk Kwan Tang,Boris Kwok Keung Fung 대한성형외과학회 2015 Archives of Plastic Surgery Vol.42 No.3

Open release remains the gold standard in the treatment of carpal tunnel syndrome in cases where conservative treatment fails. However, the efficacy of carpal tunnel release in the elderly has been debated in the literature throughout the years. This review aims to review the current evidence pertaining to the efficacy of carpal tunnel release in the elderly. Based on the current evidence, the outcome of carpal tunnel release is unpredictable in the elderly. Elderly patients are also less satisfied with the operation compared to younger patients. The authors recommend that these messages be conveyed to elderly patients before surgery. Moreover, open carpal tunnel release should be offered in the early stages of treatment whenever operative management is indicated.

Purpose: Carotid vessel wall volume (VWV) measurement on three-dimensional ultrasonography (3DUS) outperforms conventional two-dimensional ultrasonography for carotid atherosclerosis evaluation. Although time-saving semi-automated algorithms have been introduced, their clinical availability remains limited due to a lack of validation, particularly an extensive reliability analysis. This study compared inter-observer and intra-observer reliability between manual segmentation and semi-automated segmentation for carotid VWV measurements on 3DUS. Methods: Thirty-one 3DUS volume datasets were prospectively acquired from 20 healthy subjects, aged >18 years, without previous stroke, transient ischemic attack, or cardiovascular disease. Five observers segmented all volume datasets both manually and semi-automatically. The process was repeated five times. Reliability was expressed by the intraclass correlation coefficient, supplemented by the coefficient of variation. Results: Carotid VWV measurements using the common carotid artery (CCA) were more reliable than those using the internal carotid artery (ICA) or external carotid artery (ECA) for both manual and semiautomated segmentation (manual segmentation, CCA: inter-observer, 0.935; intra-observer, 0.934 to 0.966; ICA: inter-observer, 0.784; intra-observer, 0.756 to 0.878; ECA: inter-observer, 0.732; intraobserver, 0.919 to 0.962; semi-automated segmentation, CCA: inter-observer, 0.986; intra-observer, 0.954 to 0.993; ICA: inter-observer, 0.977; intra-observer, 0.958 to 0.978; ECA: inter-observer, 0.966; intra-observer, 0.884 to 0.937). Total carotid VWV measurements by manual (inter-observer, 0.922; intra-observer, 0.927 to 0.961) and semi-automated segmentation (inter-observer, 0.987; intra-observer, 0.968 to 0.989) were highly reliable. Semi-automated segmentation showed higher reliability than manual segmentation for both individual and total carotid VWV measurements. Conclusion: 3DUS carotid VWV measurements of the CCA are more reliable than measurements of the ICA and ECA. Total carotid VWV measurements are highly reliable. Semi-automated segmentation has higher reliability than manual segmentation.
