Challenges and Adaptation in Otorhinolaryngology Practice During Pandemic Lockdown: Experience from a Malaysian COVID-19 Hospital.

Malays J Med Sci 2021 Jun 30;28(3):143-150. Epub 2021 Jun 30.

COVID-19 has taken the world by storm: since the first few cases appeared in Wuhan, China in December 2019 and by June 2020 there were more than 10 million cases of COVID-19 cases worldwide. Malaysia had its first case in January 2020 and acted promptly by implementing several drastic measures to contain the disease. Subsequently, the Ministry of Health Malaysia has implemented guidelines and recommendations on the management of COVID-19. The Department of Otorhinolaryngology-Head and Neck Surgery (ORL-HNS) provides services for patients with ear, nose, throat, head and neck diseases and provides audiology, speech and language therapy, as well as undergraduate and postgraduate training. As the department's staff is heavily involved in examinations and interventions of upper aerodigestive tract problems, the challenges are distinctly different from other specialties. This article discusses how COVID-19 affected ORL-HNS services and what measures were taken in Hospital Melaka, Malaysia.

Biobutanol production from sugarcane bagasse by Clostridium beijerinckii strains.

Biotechnol Appl Biochem 2020 Sep 21;67(5):732-737. Epub 2020 Jan 21.

School of Applied Science, Temasek Polytechnic, Singapore.

Acetone-butanol-ethanol (ABE) fermentation was performed with sugarcane bagasse (SCB) hydrolysate using Clostridium beijerinckii strains. A cost-effective SCB medium was developed with no enzymatic hydrolysis and no supplementation of extra carbon source or expensive nitrogen source. One of the C. beijerinckii strains studied was able to produce butanol with butanol productivity of 1.23 g/L/day with butanol yield of 0.18 g/g of sugars from the developed medium. High utilization rate of both glucose and xylose was observed in SCB medium during ABE fermentation. This study shows that SCB is a promising substrate for cellulosic biobutanol production.

Building healthy eating habits in childhood: a study of the attitudes, knowledge and dietary habits of schoolchildren in Malaysia.

PeerJ 2016 24;4:e2651. Epub 2016 Nov 24.

Faculty of Education, University of Malaya , Kuala Lumpur , Malaysia.

Background: Overweight and obesity have increased rapidly in incidence to become a global issue today. Overweight and obesity problems are significantly linked to unhealthy dietary patterns, physical inactivity and misperception of body image. This study aimed to determine whether Malaysian children build healthy eating habits from childhood.

Methods: A survey on eating habits was conducted among primary school students in standards 4 to 6 in the state of Selangor, Malaysia. The findings of the study were reported in the form of descriptive statistics involving frequencies and percentages. Data from 400 respondents were analyzed.

Results: Our findings showed that the students understood the definition of healthy food and the types of food that are considered healthy. Although the students knew that food such as deep-fried drumsticks and hamburgers contain a high amount of saturated fat and cholesterol, these foods were still consumed by them. There was also a high consumption of foods that are fried and contain sugar, salt and saturated fat. In choosing food, two major factors contributed to the students' decisions: cleanliness (65.8%) and the preference of their parents (12.3%).

Discussion: Our findings indicate that by implementing the Integrated School Health Program (ISHP) properly, students' eating habits can be improved by creating a school with a healthy environment.
