RESUMO
Urine albumin concentration and albumin-creatinine ratio are important for the screening of early-stage kidney damage. Commutable urine certified reference materials (CRMs) for albumin and creatinine are necessary for standardization of urine albumin and accurate measurement of albumin-urine ratio. Two urine CRMs for albumin and creatinine with certified values determined using higher-order reference measurement procedures were evaluated for their commutability on five brands/models of clinical analyzers where different reagent kits were used, including Roche Cobas c702, Roche Cobas c311, Siemens Atellica CH, Beckman Coulter AU5800, and Abbott Architect c16000. The commutability study was conducted by measuring at least 26 authentic patient urine samples and the human urine CRMs using both reference measurement procedures and the routine methods. Both the linear regression model suggested by the Clinical and Laboratory Standard Institute (CLSI) guidelines and log-transformed model recommended by the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Commutability Working Group were used to evaluate the commutability of the human urine CRMs. The commutability of the human urine CRMs was found to be generally satisfactory on all five clinical analyzers for both albumin and creatinine, suggesting that they are suitable to be used routinely by clinical laboratories as quality control or for method validation of urine albumin and creatinine measurements.

BACKGROUND: In healthcare practice, ethical challenges are inevitable and their optimal handling may potentialy improve patient care. Ethical development in medical education is critical for the transition from a medical and health sciences student to an ethical healthcare practitioner. Understanding the health professions students' approaches towards practice-driven ethical dilemmas could harness i the effective ethical development in their medical education. This study attempts to identify the health professions students' approaches towards practice-driven ethical dilemmas. METHODS: An inductive qualitative evaluation was conducted on six recorded videos of health professions students' case-based online group discussions, followed by a one-hour online ethics workshop. The online ethics workshop was organized with students from the College of Medicine, College of Dental Medicine and College of Pharmacy at the University of Sharjah, and the College of Medicine at the United Arab Emirates University. . The recorded videos were transcribed verbatim and imported to the qualitative data analysis software of MAXQDA 2022. Data were analyzed applying four stages of review, reflect, reduce and retrieve and two different coders triangulated the findings. RESULTS: Six themes emerged from the qualitative analysis of the health professions students' approaches to the practice-based ethical dilemmas; (1) emotions, (2) personal experiences, (3) law and legal system, (4) professional background, (5) knowledge of medical research and (6) inter-professional education. In addition, during the case-based group discussions in the ethics workshop, students efficiently applied the relevant ethical principles of autonomy, beneficence, non-maleficence and justice in their reasoning process to reach an ethical decision. CONCLUSION: The findings of this study explained how health professions students resolve ethical dilemmas in their ethical reasoning process. This work sheds light on ethical development in medical education by gaining students' perspectives in dealing with complex clinical scenarios. The findings from this qualitative evaluation will aid academic medical institutions in developing medical and research-based ethics curriculum to transform students to ethical leaders.

Ductal arterial spasm is a very potentially dangerous incidence during percutaneous device closure of patent ductus arteriosus (PDA), which, otherwise, is a very safe catheter intervention. It is essential to notice its occurrence before device sizing and deploying. Without awareness, it can mislead device selection and can result in serious complication. In this report, we shared our nightmare of ductal spasm during transcatheter closure of PDA in two children which had led to death in one patient.

Diabetes-induced CVD is the most significant complication of prolonged hyperglycaemia. The aim of this study was to determine whether resveratrol, a polyphenol antioxidant compound, when administered at a dose that can be reasonably obtained through supplementation could prevent the development of cardiovascular complications in older, obese, diabetic rats. Diabetes was induced in 6-month old, obese, male Wistar rats via a single intravenous dose of streptozotocin (65 mg/kg). Randomly selected animals were administered resveratrol (2 mg/kg) via oral gavage daily for 8 weeks. Body weights, blood glucose levels, food intake and water consumption were monitored, and assessments of vascular reactivity, tactile allodynia and left ventricular function were performed. Resveratrol therapy significantly improved tactile allodynia and vascular contractile functionality in diabetic rats (P<0·05). There were no significant changes in standardised vasorelaxation responses, plasma glucose concentrations, water consumption, body weight, left ventricular hypertrophy, kidney hypertrophy, heart rate or left ventricular compliance with resveratrol administration. Resveratrol-mediated improvements in vascular and nerve function in old, obese, diabetic rats were associated with its reported antioxidant effects. Resveratrol did not improve cardiac function nor mitigate the classic clinical symptoms of diabetes mellitus (i.e. hyperglycaemia, polydypsia and a failure to thrive). This suggests that supplementation with resveratrol at a dose achievable with commercially available supplements would not produce significant cardioprotective effects in people with diabetes mellitus.

We tested refugee camp residents on the Thailand-Myanmar border for Taenia solium infection. Taeniasis prevalence was consistent with that for other disease-endemic regions, but seropositivity indicating T. solium taeniasis was rare. Seropositivity indicating cysticercosis was 5.5% in humans, and 3.2% in pigs. Corralling pigs and providing latrines may control transmission of these tapeworms within this camp.

INTRODUCTION: The risk of emergence and spread of antibiotic resistance is high in Southeast Asian countries and various strategies are being used to raise awareness about appropriate antibiotic use and antibiotic resistance within communities. Public engagement in science has not been widely practised in Myanmar. We describe the use of a forum theatre to engage with the community about antibiotic use. METHODS: The engagement activities took place in a peri-urban township in Yangon, Myanmar. Five preliminary story gathering workshops with the community were carried out to develop scripts and songs for the forum theatre. After that, we organised forum theatre plays between September and October 2018. Following each play we provided four simple key messages based on WHO's world antibiotic awareness week advocacy materials; 1) Antibiotics are medicines used to treat bacterial infections 2) Antibiotics are not useful for coughs and colds 3) Never use leftover antibiotics or share antibiotics with others 4) Prevent infections by regularly washing hands, preparing food hygienically, avoiding close contact with sick people, and keeping vaccinations up to date. We evaluated the engagement activities by conducting focus group discussions (FGD) with audience members. RESULTS: Ten forum theatre plays were performed on two topics; "Fever and antibiotics" and "Mixed medicines", reaching 1175 community members. Four themes emerged from our thematic analysis: 1) Knowledge dissemination, 2) Enjoyment and fun, 3) Willingness to support and recommendations for future engagement activities and 4) Preference over traditional methods of health education. We found improvement of antibiotic related knowledge and enjoyment among audience who were also willing to support future engagement activities and preferred forum theatre approach over formal health talks. CONCLUSIONS: We conclude that forum theatre is an effective innovative approach to engage and disseminate knowledge on appropriate use of antibiotics with the community in a participatory way.

Introduction: Physical therapists in Myanmar use a prescriptive model of Clinical Decision Making (CDM). Improving CDM effectiveness is one essential factor in professionalizing practice and enhancing patient outcomes. This study assesses the changes in CDM skills and behaviors using the PRECEDE-PROCEED planning Model (PPM). Methods: In the PRECEDE planning phases, we investigated the current clinical decision making knowledge, and process, clinical practice culture, and contributing factors of CDM among Myanmar physical therapists. A qualitative approach consisted of 18 in-depth interviews and one focus group discussion was used. In the PROCEED evaluation and implementation phases, we developed and presented the CDM educational book at CDM workshop, which was a 4-day intensive program in Yangon, Myanmar with 34 participants. The participant's CDM knowledge and processes were assessed before and after the educational program to explore the potential impact on implementing CDM which can ultimately improve patient care in the health settings of Myanmar. Results: In the PRECEDE phases, we explored the predisposing and reinforcing factors of Myanmar physical therapists' CDM. We found that CDM models and deliberative decision making process that is used internationally were not followed by Myanmar physical therapists who followed the physician's prescriptions. Teaching and learning emphasize a stimulus-response-repeat-outcome cycle without internal processing or application to clinical situations. Using the PROCEED model components, we developed a 14 chapters CDM workbook and a 4-day workshop as a behavioral change intervention. Participants' prior technical CDM behavior was transformed into professional CDM behavior that included an understanding of clinical practice models and improvement in the cognitive process of CDM processes. The workbook coupled with the intensive active-learning, hands-on workshop of examination and intervention procedures were effective in improving CDM. Discussion: The application of PPM provided a through understandings of current CDM process of Myanmar therapists and aided in the development of the tailored CDM educational program to improve participants' CDM. Using the PPM model for developing a set of Physical Therapy educational content and curriculum was new. The application of PPM was beneficial to use accepted clinical practice models, standardized tests and measures, set goals and clinical outcomes, reassessed to determine change and implement evidence-based practice.
RESUMO
BACKGROUND: The Pint of Science festival is the biggest annual international science festival. In May 2017, we coordinated the first Pint of Science festival in Thailand and reported our initial reflections. Building on this work, we set out to evaluate more systematically events conducted in 2018. METHODS: In 2018, we conducted Pint of Science events at four different locations in Bangkok. Overall, there were 18 talks held over six event-days in 2018. We administered 180 self-reported questionnaires as well as conducted 11 semi-structured interviews and a focus group discussion with audience members and speakers. RESULTS: Of the 180 questionnaires handed out, 125 attendees completed the questionnaire. The majority of attendees came because they were interested in science (68.0%), to learn something new (46.4%) and to enjoy themselves (44.8%). Our qualitative results confirm the quantitative findings. In addition, speakers viewed that they benefited by improving their communication skills and having the opportunity to network with scientists and non-scientists. Speakers also mentioned that such events were a good means to engage with the public, can improve the visibility of their work and potentially attract more funding. To improve the Pint of Science activities, audience members suggested to include a more diverse range of topics, more collaborations with other local research institutions and to hold the event at larger venues. CONCLUSIONS: We conclude that Pint of Science was well received in Bangkok with recommendations to improve minor issues related to practicalities and logistics.

The utility of single-chain Fv proteins as therapeutic agents would be realized if the circulating lives of these minimal antigen-binding polypeptides could be both prolonged and adjustable. We have developed a general strategy for creating tailored monoPEGylated single-chain antibodies. Free cysteine residues were engineered in an anti-TNF-alpha scFv at the C-terminus or within the linker segments of both scFv orientations, V(L)-linker-V(H) and V(H)-linker-V(L). High-level expression of 10 designed variant scFv proteins in Pichia pastoris allowed rapid purification. Optimization of site-specific conjugate preparation with 5, 20 and 40 kDa maleimide-PEG polymers was achieved and a comparison of the structural and functional properties of the scFv proteins and their PEGylated counterparts was performed. Peptide mapping and MALDI-TOF mass spectrometric analysis confirmed the unique attachment site for each PEG polymer. Independent biochemical and bioactivity analyses, including binding affinities and kinetics, antigenicity, flow cytometric profiling and cell cytotoxicity rescue, demonstrated that the functional activities of the 10 designed scFv conjugates are maintained, while scFv activity variations between these alternative assays can be correlated with conjugate and analytical designs. Pharmacokinetic studies of the PEGylated scFv in mice demonstrated up to 100-fold prolongation of circulating lives, in a range comparable to clinical antibodies.
