MATERIALS AND METHODS: Three groups of data were analysed from the BDTR over the 10-year period. Epidemiological data, blood parameters and dialysis are key performance indicators.
RESULTS: There are increments in prevalence and incidence of treated ESKD patients in Brunei over 10 years, especially with haemodialysis (HD). The projected prevalence and incidence showed an anticipated annual increase of 42.2 per million population (pmp) and 9.9 pmp respectively. Diabetes mellitus (DM) (79%) was the main cause of ESKD. HD (86%), peritoneal dialysis (PD) (9%) and transplant (5%) were the main modalities of kidney replacement therapy in 2020. Cumulative results over the decade showed significant improvements in serum phosphate, peritonitis rates and HD blood flow rates. PD patients have better survival rates, lower systolic blood pressure and better adequacy. PD survival (patient survival of 91%, 73% and 56% at 1, 3 and 5 years respectively) was superior to HD survival (86% and 64% at 1 and 2 years, respectively), but patient demographics (age and DM status) were different. The 2020 dataset showed satisfactory anaemia management but mineral bone disease management was sub-optimal. Seventy percent of prevalent HD patients had arteriovenous fistula access. Thirty-two percent and fifty-two percent of HD and PD patients, respectively, achieved target dialysis adequacy. Peritonitis rate was 0.3 episodes per patient year.
CONCLUSION: Brunei has a high incidence and prevalence of treated ESKD in the last decade, especially DM-related ESKD. This study has identified many specific areas to be targeted for improvements and provided evidence for further proliferation of PD and transplant preference policy.
METHOD: Between November 2009 and July 2010, outpatients from 45 countries who met the criteria for stable CAD were recruited into the registry. Baseline characteristics were documented at enrolment, and patients were reassessed during their annual visits over a five-year follow-up period. Key outcomes measured were sudden death and cardiovascular (CV) death, non-CV death and CV morbidity.
RESULTS: At baseline, 33,283 patients were available for analysis within the registry; 380 and 27 were Malaysians and Bruneians, respectively. The mean ages of Malaysian/Bruneian patients and the rest of the world (RoW) were 57.83 ±9.98 years and 64.23 ± 10.46 years, respectively (p<0.001). The median body mass index values were 26.6 (24.4-29.6) kg/m2 and 27.3 (24.8-30.3) kg/m2, respectively (p=0.014). Malaysian/Bruneian patients had lower rates of myocardial infarction (54.55% versus 59.76%, p=0.033) and higher rates of diabetes (43.24% versus 28.99%, p<0.001) and dyslipidaemia (90.42% versus 74.66%, p<0.001) compared with the RoW. Measured clinical outcomes in Malaysian and Bruneian patients at 2-years follow-up were low and generally comparable to the RoW.
CONCLUSION: Malaysian/Bruneian patients with stable CAD tend to be younger with poorer diabetic control compared with the RoW. However, they had similar outcomes as the main registry following two years of treatment.
MATERIALS AND METHODS: The cancer registry from 1986 to 2014 maintained by the State Laboratory was retrospectively reviewed. The age standardized rates (ASR) and the age specific incidence rates (ASIR) were calculated. Non NPC tumors were excluded from the study.
RESULTS: Altogether, there were a total of 450 NPC cases diagnosed accounting for 4.4% of all total cancer cases over the study period, declining from 10.3% in 1986-1990 to 2.3% in 2011-2014. The most common tumor type was the undifferentiated carcinoma (96.4%). The case characteristics were mean age 50.4 ± 14.4 years old, male 69%, and predominately Malays 74.4%, followed by Chinese 16.7%. The mean age of diagnosis increased over the study period from 45.6 ± 17.1 years (1986-1989) to 54.1 ± 12.5 years (ANOVA, p<0.01 for trend). There were no differences in the mean age of diagnosis between the ethnic groups or genders. The ASR showed a declining trend from 11.1 per 100,000 in 1986-1990 to 5.95 per 100,000 in 2011-2014, similar trends been observedfor both genders. Among the age groups, declining trends were seen in all the other age groups apart from the >70 years group. The overall ASRs for the Malays and Chinese were 7.92/100,000 and 8.83/100,000 respectively, both showing declining trends.
CONCLUSIONS: The incidence of NPC in Brunei Darussalam is comparable to rates reported from Singapore and Malaysia, but higher than rates reported from the other Southeast Asian nations. Unlike higher rates reported for Chinese compared to the Malays in other countries, the rates between the Malays and Chinese in our study was comparable. Importantly, the ASR is declining overall and for both genders and ethnic groups.
OBJECTIVES: This study examined past month patterns of substances use and its gender difference among adolescents.
METHODS: Cross-sectional samples among adolescents aged 13-16 years who completed the Global School-based Student Health Survey (GSHS) from eight ASEAN countries were included in the analysis (n = 40,212).
RESULTS: Prevalence of past month any tobacco use was relatively high in Brunei, Indonesia, Malaysia, Thailand, and the Philippines (11-15%), but prevalence of dual cigarette and other forms of tobacco use was about 2-5% in the five countries. Past month alcohol consumption prevalence was also high in Thailand, Viet Nam, and the Philippines (16-24%), compared to the rest countries (1.4-8.2%). Moreover, prevalence of the concurrent alcohol and tobacco use was higher in Thailand and the Philippines (7 and 10%, respectively), particularly in boys (13 and 15%, respectively). Conclusions/importance: Almost 30-40% of the boys and 10-20% of girls in Malaysia, Philippines, Thailand, and Viet Nam are engaged in at least one of the two risk behaviors, and the concurrent alcohol and tobacco use was also relatively high among boys in those countries (5-15%). This study may provide some valuable insights on alcohol and tobacco policy in the region and requires to begin prevention and treatment programs in ASEAN member states.
METHODS: This is a retrospective study examining CRC data for the period 2007 to 2017 retrieved from a population based cancer registry in Brunei Darussalam. A total of 728 patients were included in the analysis. Kaplan Meier method was used to estimate survival rates. Univariate analysis using log-rank test was used to examine the differences in survival between groups. Multivariate analysis using Cox PH regression was used to estimate hazard of death and obtain significant predictors that influence CRC patients' survival.
RESULTS: The median survival time for colorectal, colon and rectal cancer patients were 57.0, 85.8 and 40.0 months respectively. The overall 1-, 3- and 5- year survival rates for CRC patients were 78.0%, 57.7% and 49.6% respectively. In univariate analysis, age at diagnosis, ethnicity, cancer stage, tumour location and histology were found to have significant difference in CRC patients' survival. In the Cox PH analysis, older age (≥70 years), cancer stage, ethnicity and other histological type were determined as associated factors of CRC patients' survival.
CONCLUSION: This study found the overall 5-year survival rate of CRC in Brunei Darussalam is similar to that in some Asian countries such as Singapore and Malaysia. However, more efforts need to be carried out in order to raise awareness of CRC and improve the survival of CRC patients.
MATERIALS AND METHODS: Lethality was calculated as the rate of deaths in a determinate moment from the outbreak of the pandemic out of the total of identified positives for COVID-19 in a given area/nation, based on the COVID-John Hopkins University website. Lethality of countries located within the 5th parallels North/South on 6 April and 6 May 2020, was compared with that of all the other countries. Lethality in the European areas of The Netherlands, France and the United Kingdom was also compared to the territories of the same nations in areas with a non-temperate climate.
RESULTS: A lower lethality rate of COVID-19 was found in Equatorial countries both on April 6 (OR=0.72 CI 95% 0.66-0.80) and on May 6 (OR=0.48, CI 95% 0.47-0.51), with a strengthening over time of the protective effect. A trend of higher risk in European vs. non-temperate areas was found on April 6, but a clear difference was evident one month later: France (OR=0.13, CI 95% 0.10-0.18), The Netherlands (OR=0.5, CI 95% 0.3-0.9) and the UK (OR=0.2, CI 95% 0.01-0.51). This result does not seem to be totally related to the differences in age distribution of different sites.
CONCLUSIONS: The study does not seem to exclude that the lethality of COVID-19 may be climate sensitive. Future studies will have to confirm these clues, due to potential confounding factors, such as pollution, population age, and exposure to malaria.
