Fulltext Occupancy implications on indoor air quality (IAQ) in selected primary school classrooms around Kuantan, Pahang

Hazrin AH, Maryam Z, Hizrri A, Mohd Shukri MA, Norhidayah A, Samsuddin N

Malaysian Journal of Public Health Medicine, 2017;17 Special(1): 95-105.

The effects of children’s exposure on high concentration of airborne pollutants at schools often associated with increased rate of absenteeism, low productivities and learning performances, and development of respiratory problems. Recent studies have found that the presence of occupants in the classroom seems to give major effect towards the elevation of concentration of airborne pollutants in indoors. In order to evaluate and further understand on the significance of occupancy factor on IAQ, this study has been designed to determine and compare the level of selected physical (particulate matter (PM)) and chemical (carbon dioxide (CO2) and temperature) IAQ parameters and biological contaminants via colony forming unit (CFUm-3 ) for bacteria and fungi inside the selected classrooms during occupied and non-occupied period (first objective). The second objective is to describe the possible sources of airborne pollutants inside the classrooms at the selected primary schools around Kuantan, Pahang. Assessments of physical and chemical IAQ were done by using instruments known as DustMate Environmental Dust Detector and VelociCalc® MultiFunction Ventilation Meter 9565.The data were recorded every 30 minutes for 8 hours during schooldays and weekend at the selected sampling point in the classrooms. For microbial sampling, Surface Air System Indoor Air Quality (SAS IAQ) was used to capture the bacteria and fungi. The data obtained were compared with the established standard reference known as the Industrial Code of Practice on Indoor Air Quality (2010) constructed by the Department of Occupational Safety and Health (DOSH), Malaysia. This study has found that some of the IAQ parameters in the selected classrooms were exceeding the established standards during occupied period in schooldays compared to non-occupied period during weekend. Findings of this study provide the insights for future research including the site selection of school, arrangement of the classrooms and numbers of students per class.

PMID: 16317660 DOI: 10.1002/ptr.1759

The methanol, n-butanol, chloroform and water extracts obtained from the root of Eurycoma longifolia Jack were assayed using methylene blue assay to evaluate its cytotoxic effect against KB, DU-145, RD, MCF-7, CaOV-3, MDBK cell lines. The results showed that all the root extracts except the water extract of E. longifolia produced significant cytotoxic effect on these cell lines. However, no significant cytotoxic effect was detected on MDBK (kidney) normal cell line. 9-methoxycanthin-6-one, an alkaloid, was detected in each extract with different intensities by reversed-phase high performance liquid chromatography.

INTRODUCTION: Potassium level is measured for patients with high risk of hyperkalemia in the emergency department (ED) using both blood gas analyser (BGA) and biochemistry analyser (BCA). The study was conducted to evaluate the correlation and agreement of potassium measurement between BGA and BCA.
MATERIALS AND METHODS: This is a prospective cross-sectional study on the data obtained from Hospital Universiti Sains Malaysia (Hospital USM) from Jun 2018 until May 2019. Blood samples were taken via a single prick from venous blood and sent separately using 1ml heparinised syringe and were analysed immediately in ED using BGA (Radiometer, ABL800 FLEX, Denmark) and another sample was sent to the central laboratory of Hospital USM and analysed by BCA (Architect, C8000, USA). Only patients who had potassium levels ≥5.0mmol/L on blood gas results were included. A total of 173 sample pairs were included. The correlation and agreement were evaluated using Passing and Bablok regression, Linear Regression and Bland-Altman test.
RESULT: Of the 173 sample pairs, the median of potassium level based on BGA and BCA were 5.50mmol/L (IQR: 1.00) and 5.90mmol/L (IQR: 0.95) respectively. There was significant correlation between two measurements (p<0.001, r: 0.36). The agreement between the two measurements showed within acceptable mean difference which was 0.27 mmol/L with 95% limit of agreement were 1.21mmol/L to 1.73mmol/L.
CONCLUSION: The result of blood gas can be used as a guide for initial treatment of hyperkalaemia in critical cases where time is of the essence. However, BCA result is still the definitive value.

Supraventricular tachycardia (SVT) is the commonest tachyarrhythmia among paediatric age group. Modified Valsalva manoeuvre can be attempted in a stable child. We discuss here a case of a 6-year-old boy who presented with stable SVT and iced towel was applied to his face to revert the tachyarrhythmia. This method was well tolerated by the child without any complications. The SVT was successfully reverted, and pictures were taken to capture the simple but effective method.

INTRODUCTION: Cardiopulmonary resuscitation (CPR) is indeed a basic skill that should be acquired by everyone in the community. Early CPR is an important element in the chain of survival and home-based child daycare (HBCD) caregivers play a vital role as early responders in case of out-of-hospital cardiac arrest (OHCA). The study aims to determine the level of knowledge and attitude of CPR among HBCD caregivers in Kelantan and the factors that contribute to them. This study covers a research gap in Kelantan, Malaysia, evaluating HBCD caregivers' knowledge and attitudes towards CPR.
MATERIALS AND METHODS: This was a quantitative crosssectional study conducted from November 2020 until March 2021 which involves 139 HBCD caregivers in Kelantan. Validated questionnaire was used which consisted of 27 questions based on demography, knowledge and attitude towards CPR. The data was keyed in and analysed using software SPSS version 26.
RESULTS: A total of 139 respondents participated in the study. The mean attitude score obtained by the caregivers was 16.67 with SD = 4.22. There were 89 caregivers (64%) with poor knowledge among the 139 HBCD caregivers in the study compared to 50 HBCD caregivers (36%) who had good knowledge. Caregivers who were exposed with CPR training had 5.91 higher odds of having good CPR knowledge compared to those without being exposed to CPR training (Wald-statistic (df) = 21.12 (1), OR (95% CI) = 5.91 (2.77, 12.61), p<0.001). Caregivers with experience in handling CPR were 5.91 of higher odds in having good CPR knowledge compared to those without the experience in handling CPR when adjusted for the duration of caregiver's experience (Wald-statistic (df) = 21.12 (1), OR (95% CI) = 5.91 (2.77, 12.61), p<0.001). HBCD caregivers' experience was the only variable that had a significant p-value when tested in the regression model (p = 0.023).
CONCLUSION: The findings revealed that HBCD caregivers in Kelantan had inadequate CPR knowledge, potentially increasing the risk of OHCA. Planned and regular training for them is mandatory. Exposure to CPR was the associated factor that contributes to knowledge level among HBCD caregivers whereas years of experience as HBCD caregivers influence attitude towards CPR.

Dengue fever is one of the most common diagnoses in patients presenting with acute febrile illness in tropical countries. Borrelia, on the other hand, is the cause of vector-borne infections of relapsing fever and Lyme disease. While co-infections of dengue with chikungunya, Zika, malaria, influenza and typhoid have been reported, clinical cases of Borrelia infections have never been reported in Malaysia. Based on available evidence, this is the first case series to report dengue fever and Borrelia spp. co-infection. All three patients in this report were admitted to medical wards on day 3 to day 8 of illness for dengue fever as evidenced by a positive dengue NS1 antigen test. The clinical manifestations were typical of dengue fever, with all patients having high grade fever, myalgia, and arthralgia. All patients also had thrombocytopenia. Features of severe dengue, such as shock, hemorrhage and impaired consciousness were absent. Borrelia DNA were detected in the blood samples of the patients. However, all the patients denied having skin lesions and a history of insect bites. All the patients were given intravenous fluid therapy and were discharged after 3 to 5 days of hospitalization.
