The Effectiveness of Narrow Band Uvb (Nb-Uvb) In the Treatment of Pityriasis Lichenoides Chronica (PLC) In Vietnam

AIM: This prospective clinical study presents the experiences with NB-UVB monotherapy in the treatment of PLC on Vietnamese patients. METHODS: We enrolled at National Hospital of Dermatology and Venereology (NHDV), Vietnam, 29 PLC patients with generalised disease involving at least 60% of the total body surface (based on Nine’s Rule) and/or failed to respond to other modalities of treatment. Patients were treated with NB-UVB followed the guideline of the psoriatic treatment of AAD-2010, three times weekly. RESULTS: A complete response (CR) was seen in 24 out of 29 PLC patients (82.8%) with a mean cumulative dose of 9760.5 mJ/cm2 after a mean treatment period of 4.6 weeks (13.8 ± 7.4 exposures). Mild side effects were observed: 69% erythema minimum, 55.2% irritation related to dry skin. No severe side effects were seen during the study. No relapses occurred in 24 CR patients within a mean period of 3 months after the last treatment. CONCLUSION: NB-UVB therapy is an effective and safe option for the treatment and management of PLC

Efficacy Of 10% Potassium Hydroxide Solution Versus 10% Salicylic Acid Ointment in Treatment of Molluscum Contagiosum - the Low - Cost Dermatologic Therapy in Vietnam

BACKGROUND: Molluscum contagiosum is a common viral disease primarily affecting children. AIM: The objective is to compare the efficacy of 10% potassium hydroxide (KOH) solution versus 10% salicylic pomade in the treatment of molluscum contagiosum. METHODS: Clinical trials on 70 patients were randomised into 2 groups: 39 patients treated with 10% KOH solution and 31 patients treated with 10% salicylic pomade. The evaluation was based on the complete clearance of lesions, side effects and complications of the drug. RESULTS: The clearance of all lesions after 2, 4, 6, 8 weeks of treatment in both groups were 7.7%; 23.1%; 53.8%; 79.5% and 0%; 3.2%, 9.7% 22.6%, respectively (p < 0.05). Side effects were seen in both groups include burning (76.9% versus 19.4%; p < 0.05); redness (59% versus 14%; p < 0.01); desquamation (12.8% versus 19.3%; p < 0.05). CONCLUSION: The efficacy of KOH solution in the treatment of MC was better than that of salicylic pomade and both products are safe, effective, and easy to apply at home

ADAPTAÇÃO CULTURAL E VALIDAÇÃO PSICOMÉTRICA DO QUESTIONÁRIO SELF EFFICIENCY AND PERFORMANCE IN SELF-MANAGEMENT SUPPORT (SEPSS) EM ESTUDANTES DE GRADUAÇÃO EM ENFERMAGEM E MEDICINA DE BANGLADESH

In an aging society, healthcare professionals and students face increasing demands to actively involve patients in the decision-making process regarding their health conditions and lifestyles. Self-management support is considered a best practice that aligns with the patient-centered care paradigm in Bangladesh. However, there is currently no instrument available to assess healthcare professionals’ competencies in this field, particularly during their early education and training period. The aim of this study was to translate the Self Efficiency and Performance in Self-management Support (SEPSS) instrument into Bangla and validate its psychometric properties in a sample of undergraduate healthcare students in Bangladeshi higher education institutions. A cross-sectional study was conducted to assess the reliability, validity, and cultural appropriateness of the Bangla version of SEPSS-36 among 486 nursing and medical students. Confirmatory factor analysis was carried out using the chi-square model fit index (CMIN), comparative fit index (CFI), and Root Mean Square Error of Approximation (RMSEA) as fit indices. The internal consistency was estimated by the Cronbach alpha coefficient. The results indicate that the CMIN (2.658) and RMSEA (.058) values suggest that the sample data and hypothetical model are an acceptable fit in the analysis, with satisfactory CFI values (.895). The reliability for all SEPSS dimensions was acceptable. The Bangla version of the SEPSS questionnaire is a valid and reliable instrument that can assist healthcare educators and researchers in determining students’ competencies within this domain.Numa sociedade envelhecida, os profissionais de saúde e os estudantes enfrentam exigências cada vez maiores para envolver ativamente os pacientes no processo de tomada de decisão em relação às suas condições de saúde e estilos de vida. O apoio à autogestão é considerado uma prática recomendada que está alinhada com o paradigma de cuidados centrados no paciente em Bangladesh. No entanto, atualmente não existe um instrumento disponível para avaliar as competências dos profissionais de saúde nesse campo, especialmente durante o período inicial de educação e formação. O objetivo deste estudo foi traduzir o instrumento Self Efficiency and Performance in Self-management Support (SEPSS) para o bengali e validar as suas propriedades psicométricas numa amostra de estudantes de saúde de graduação em instituições de ensino superior de Bangladesh. Foi realizado um estudo transversal para avaliar a confiabilidade, validade e adequação cultural da versão em bengali do SEPSS-36 entre 486 estudantes de enfermagem e medicina. A análise fatorial confirmatória foi conduzida utilizando o índice de ajustamento do modelo qui-quadrado (CMIN), o índice de ajustamento comparativo (CFI) e o erro quadrado médio de aproximação (RMSEA) como índices de ajustamento. A consistência interna foi estimada pelo coeficiente alfa de Cronbach. Os resultados indicam que os valores de CMIN (2,658) e RMSEA (0,058) sugerem que os dados da amostra e o modelo hipotético têm um ajustamento aceitável na análise, com valores de CFI satisfatórios (0,895). A confiabilidade de todas as dimensões do SEPSS foi aceitável. A versão em bengali do questionário SEPSS é um instrumento válido e fiável que pode ajudar os educadores e investigadores em saúde a determinar as competências dos estudantes nesta área

Safety and efficacy of fluoxetine on functional outcome after acute stroke (AFFINITY): a randomised, double-blind, placebo-controlled trial

Background Trials of fluoxetine for recovery after stroke report conflicting results. The Assessment oF FluoxetINe In sTroke recoverY (AFFINITY) trial aimed to show if daily oral fluoxetine for 6 months after stroke improves functional outcome in an ethnically diverse population. Methods AFFINITY was a randomised, parallel-group, double-blind, placebo-controlled trial done in 43 hospital stroke units in Australia (n=29), New Zealand (four), and Vietnam (ten). Eligible patients were adults (aged ≥18 years) with a clinical diagnosis of acute stroke in the previous 2–15 days, brain imaging consistent with ischaemic or haemorrhagic stroke, and a persisting neurological deficit that produced a modified Rankin Scale (mRS) score of 1 or more. Patients were randomly assigned 1:1 via a web-based system using a minimisation algorithm to once daily, oral fluoxetine 20 mg capsules or matching placebo for 6 months. Patients, carers, investigators, and outcome assessors were masked to the treatment allocation. The primary outcome was functional status, measured by the mRS, at 6 months. The primary analysis was an ordinal logistic regression of the mRS at 6 months, adjusted for minimisation variables. Primary and safety analyses were done according to the patient's treatment allocation. The trial is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12611000774921. Findings Between Jan 11, 2013, and June 30, 2019, 1280 patients were recruited in Australia (n=532), New Zealand (n=42), and Vietnam (n=706), of whom 642 were randomly assigned to fluoxetine and 638 were randomly assigned to placebo. Mean duration of trial treatment was 167 days (SD 48·1). At 6 months, mRS data were available in 624 (97%) patients in the fluoxetine group and 632 (99%) in the placebo group. The distribution of mRS categories was similar in the fluoxetine and placebo groups (adjusted common odds ratio 0·94, 95% CI 0·76–1·15; p=0·53). Compared with patients in the placebo group, patients in the fluoxetine group had more falls (20 [3%] vs seven [1%]; p=0·018), bone fractures (19 [3%] vs six [1%]; p=0·014), and epileptic seizures (ten [2%] vs two [<1%]; p=0·038) at 6 months. Interpretation Oral fluoxetine 20 mg daily for 6 months after acute stroke did not improve functional outcome and increased the risk of falls, bone fractures, and epileptic seizures. These results do not support the use of fluoxetine to improve functional outcome after stroke

Using Think-Pair-Share Strategy to Support Students in Speaking Lessons

Improving speaking skills plays an important role for anyone who pursues language proficiency, especially in the English language. While no one can contradict the fundamental value of this productive skill, speaking, as mentioned by Castillo (2007), poses challenges to students since it concerns complex constituents such as pronunciation, stress patterns, vocabulary or grammatical structures. Among countless cooperative strategies, Think-Pair-Share, proposed by Azlina (2010) can be regarded as a stimulating option to support students in improving their speaking capabilities. This study was set out to evaluate applying Think-Pair-Share strategy in the classroom to foster students’ speaking skills and engagement in speaking activities. 35 students in the AP (Advanced Program) at Thai Nguyen University of Economics and Business Administration (TUEBA) were chosen as target participants of the study. This research was anchored on a qualitative basis, and data were collected from three methods, including observation sheets, focus group and individual interviews, to ensure the principle of triangulation. Based on the findings, the researcher attempted to provide some modifications in applying the Think-Pair-Share technique so that it can be effectively exploited to give support to language learners in their speaking skills

Technical trading in Asia based on E/P ratio

Our first major finding is the positive correlation between the dependent variable - market return and the following independent variables: E/P ratio, short spread and long spread in the Asian and Oceanian markets. However, the results are not statistically significant. Secondly, we have constructed three different investment portfolios: switching portfolio using short spread, switching portfolio using long spread and benchmark portfolio. We have found out that most of the switching portfolios using short spread outperform the other two. Again, the differences are not significant. Findings of this study are of importance for investors who are keen on investing in Asian and Oceanian equity markets. Moreover, this is the first paper to conduct a comprehensive study in a wide range of Asian countries. Therefore, the paper serves as foundation for future research.BUSINES

Digital literacy, online security behaviors and E-payment intention

E-payment is a key component of e-commerce, facilitating improved user efficiency and fostering the intent to use e-commerce in the digital realm and the international integration arena. This study investigates the joint impact of digital literacy on two similar but fundamentally different activities which are security control behavior and e-payment continuance intention. This research contributes to the growing field of literature in two ways. First, the study examines Digital Literacy, which distinguishes three broad dimensions - Tech Familiarity, Policy understanding, Awareness of institutional surveillance, and its association with Security control Behaviors and E-payment continuance intention. Second, the study tests the mediator effect of Security control Behaviors on the relationship between Digital Literacy and E-payment Intention. The data were collected by using both offline and online survey methods across the national scope, employing a quota sampling approach to encompass a wide range of consumer demographics. Structural equation modeling with the sample of Vietnamese respondents was applied to test the influence of digital literacy on customers’ security control behavior and intention to use e-payments. The results endorse that 1) digital literacy has an important impact on online security behavior; 2) digital literacy bridges a strong direct association with e-payment continuance Intention and indirect through online security behavior. This study suggests several theoretical and practical implications from the findings, as well as limitations and future directions

Phase I Clinical Trial Using Autologous Ex Vivo Expanded NK Cells and Cytotoxic T Lymphocytes for Cancer Treatment in Vietnam

(1) Background: Immune cell therapy recently attracted enormous attention among scientists as a cancer treatment, but, so far, it has been poorly studied and applied in Vietnam. The aim of this study was to assess the safety of autologous immune cell therapy for treating lung, liver, and colon cancers&mdash;three prevalent cancers in Vietnam. (2) Method: This was an open-label, single-group clinical trial that included 10 patients with confirmed diagnosis of colon, liver, or lung cancer, conducted between March 2016 and December 2017. (3) Results: After 20&ndash;21 days of culture, the average number of cytotoxic T lymphocytes (CTLs) increased 488.5-fold and the average cell viability was 96.3%. The average number of natural killer cells (NKs) increased 542.5-fold, with an average viability of 95%. Most patients exhibited improved quality of life, with the majority of patients presenting a score of 1 to 2 in the Eastern Cooperative Oncology Group (ECOG) performance status (ECOG/PS) scale, a decrease in symptoms on fatigue scales, and an increase in the mean survival time to 18.7 months at the end of the study. (4) Conclusion: This method of immune cell expansion met the requirements for clinical applications in cancer treatment and demonstrated the safety of this therapy for the cancer patients in Vietnam
