Basic fibroblast growth factor (bFGF) is angiogenic and effective in down-regulating excess collagen production. The aim of this study is to evaluate the effectiveness of vitamin E (Tocotrienol Rich Fraction) in altering the level of bFGF, a cytokine involved in the scar formation process. In this model, normal human fibroblasts were treated with various concentrations of vitamin E at different time frames. The levels of bFGF were determined by Enzyme-Linked Immunosorbant Assay (ELISA). This study demonstrated that Tocotrienol Rich Fraction (TRF) stimulated bFGF production by fibroblast and postulate that vitamin E may decrease aberrant scar formation.

There is a need to design and develop an affordable motorized vehicle for better mobility among physical disabilities. This study aimed is to initiate appropriate and affordable materials to develop an accessible motorized wheelchair. It includes the feasibility study of the existing used wheelchair, the system used and the characteristic of the physical disabilities symptom. Through the observation, an existing motorized wheelchair uses stainless steel as the main structure, manipulating the shelves heavy-duty accessories, electrical component, heavy-duty battery and car pulley system in which the weight accumulates approximately 100 kg. The heavyweight wheelchair cannot be folded and put inside the car. It also needs to have a special carrier to carry the wheelchair. The field research has also been conducted to evaluate the existing wheelchair system in the market with various systems used, components, and motors material used in the area of technical, usability and comfort before start to redesigning the wheelchair. The results of the study would include the background needs of the characteristic of physical disabilities. The available high-grade aluminium materials will be used to support the mobility and their relevant properties. The design will be done all the way and the specification will be used as an instrument data for the motorized vehicle. The selection of design features, documentation of design procedures and results will be used to create a P.O.C (Prove of Concept) prototype for the meant vehicle. The user will use the preliminary prototyping test and the data (result) will be used to improvise the wheelchair prototype. The second improvised prototype will undergo the second user testing in the area of reliability, stabilization of system, and ease of usage. The results expected will be observed and tested by the user to lead towards the recommendation of the motorized wheelchair design.

Abstract:
Differences in clinical manifestations between strains of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been reported. This retrospective descriptive study compares the clinical and demographic characteristics of all confirmed coronavirus disease (COVID-19) cases admitted to the National Isolation Centre (NIC) in the first wave and at the beginning of the second wave of the pandemic in Brunei Darussalam.
Methods:
All COVID-19 cases admitted to the NIC between 9 March and 6 May 2020 (first wave) and 7–17 August 2021 (second wave) were included. Data were obtained from NIC databases and case characteristics compared using Student’s t-tests and chi-squared tests, as appropriate.
Results:
Cases from the first wave were significantly older than those from the second wave (mean 37.2 vs 29.7 years, P<0.001), and a higher proportion reported comorbidities (30.5% vs 20.3%, P=0.019). Cases from the second wave were more likely to be symptomatic at admission (77.7% vs 63.1%, P<0.001), with a higher proportion reporting cough, anosmia, sore throat and ageusia/dysgeusia; however, myalgia and nausea/vomiting were more common among symptomatic first wave cases (all P<0.05). There was no difference in the mean number of reported symptoms (2.6 vs 2.4, P=0.890).
Discussion
Our study showed clear differences in the profile of COVID-19 cases in Brunei Darussalam between the first and second waves, reflecting a shift in the predominating SARS-CoV-2 strain. Awareness of changes in COVID-19 disease manifestation can help guide adjustments to management policies such as duration of isolation, testing strategies, and criteria for admission and treatment.

Introduction: Diabetic foot infection is often associated with
high morbidity, disability and poor quality of life. This study
focuses on the demography, the number of repetitive
surgery and length of stay in hospital of patients with
diabetic foot infection.
Method: This is a retrospective observational study. Patients
who were admitted to the Orthopaedic ward of Hospital
Segamat (HS), Johor, Malaysia from January 2016 to
December 2018 and required surgical intervention were
included in the study. Data was collected from the computer
system of HS and medical notes of patients.
Results: 35.6% of the total orthopaedic emergency surgeries
performed were for patients with diabetic foot infection, 25%
of the surgical procedures performed were major
amputations of lower limb and 40% of the patients with
diabetic foot infection required more than one surgical
operation.
Discussion: The demographics of the patients is consistent
with the demographics of Malaysia where majority of them
are Malays followed by Chinese, Indians and others. Despite
being only 10% of total admission to the department, this
group of patients contributed to 35.6% of the total
emergency surgeries performed. The amputation rate in the
centre is comparable to the other local studies. The average
length of stay in hospital was found to be shorter compared
to overseas due to different rehabilitation protocols.

From late December 2019, an outbreak of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occurred in Wuhan, China and has spread globally resulting in a pandemic. Brunei Darussalam reported its first case of COVID-19 on 9 March 2020. Several measures were implemented to prevent a national outbreak. We report our experience with surveillance of patients requiring admission in all government hospitals. We detected one positive case, and through contact tracing two further cases were detected. Therefore, without this screening programme, these cases would likely have been missed, leading to further nosocomial and community spread.

In any infectious disease outbreak, early diagnosis, isolation of cases and quarantine of contacts are central to disease containment. In Brunei Darussalam, suspected cases of coronavirus disease 2019 (COVID-19) were quarantined either at home or at designated centres and were tested immediately for severe acute respiratory syndrome coronavirus 2. We report on 10 cases of COVID-19 that initially tested negative for COVID-19 and were positive on re-testing after becoming symptomatic. These cases comprised 3.8% of the 266 total confirmed COVID-19 cases in Brunei Darussalam as of 9 July 2021, when this study was conducted. All the cases were in quarantine at home and were tested early during their quarantine period. Since then, home quarantine has been replaced by quarantine at designated centres only, with testing on the 12th day of quarantine.

Objective: Patients who recover from coronavirus disease (COVID-19) infection are at risk of long-term health disorders and may require prolonged health care. This retrospective observational study assesses the number of health-care visits before and after COVID-19 infection in Brunei Darussalam.
Methods: COVID-19 cases from the first wave with 12 months of follow-up were included. Health-care utilization was defined as health-care visits for consultations or investigations. Post-COVID condition was defined using the World Health Organization definition.
Results: There were 132 cases; 59.1% were male and the mean age was 37.1 years. The mean number of health-care visits 12 months after recovery from COVID-19 (123 cases, 93.2%; mean 5.0 ± 5.2) was significantly higher than the prior 12 months (87 cases, 65.9%, P<0.001; mean 3.2 ± 5.7, P<0.001). There was no significant difference when scheduled COVID-19 visits were excluded (3.6 ± 4.9, P = 0.149). All 22 cases with moderate to critical disease recovered without additional health-care visits apart from planned post-COVID-19 visits. Six patients had symptoms of post-COVID condition, but none met the criteria for diagnosis or had alternative diagnoses.
Discussion: There were significantly more health-care visits following recovery from COVID-19. However, this was due to scheduled post-COVID-19 visits as per the national management protocol. This protocol was amended prior to the second wave to omit post-COVID-19 follow-up, except for complicated cases or cases with no documented radiological resolution of COVID-19 pneumonia. This will reduce unnecessary health-care visits and conserve precious resources that were stretched to the limit during the pandemic.
