Abstract: Objectives: This study aimed to determine the optimal cutoff value for fever based on temperature measurements of different body surfaces using a non-contact infrared thermometer. Methods: A total of 229 participants were conveniently sampled for this clinical diagnostic study. Oral temperature was measured using a mercury thermometer, while the temperatures of the forehead, neck, and wrists were measured using a non-contact infrared thermometer. The differences and linear relationships between the temperature measurements of different body surfaces and oral temperature were analyzed using statistical methods. Receiver operating characteristic (ROC) curves were constructed to determine the optimal cutoff values for fever on the forehead, neck, and wrists. Results: The optimal cutoff values for fever on the neck, forehead, and wrists were 37.1°C, 36.9°C, and 36.8°C, respectively, as measured by the non-contact infrared thermometer. Conclusion: The non-contact infrared thermometer is a reliable tool for measuring body surface temperatures. The optimal cutoff values for fever using a non-contact infrared thermometer are 37.1°C for the neck, 36.9°C for the forehead, and 36.8°C for the wrists.

Abstract: Particulate pollution and traffic noise from the Dong – Tay Avenue created problems in the surrounding areas, especially when traffic volume was very high and vehicles ran at high speeds. Vehicular, dust and noise problems were generated by various kinds of vehicles like trucks, buses, automobiles, and motorcycles. This study aimed to determine the influence of dust and noise generated from traffic activities the Dong – Tay Avenue. Particulate matter concentrations (PM1.0, PM2.5, PM5.0, PM10) and noise levels were measured at 7 sites along the avenue in March and October from 2021 to 2022. The research results showed that the noise levels (73.1 ÷ 84.4 dBA) exceeded the allowable threshold of the National Technical Regulation on noise (QCVN26:2010/BTNMT; noise level < 70 dBA). Additionally, the dust concentrations (PM1.0: 6.6 ÷ 18.8 μg/m3; PM2.5: 9.2 ÷ 35.7 μg/m3; PM5.0: 11.2 ÷ 47.0 μg/m3; PM10: 13.0 ÷ 49.7 μg/m3) were lowered the permissible thresholds of the National Technical Regulation on ambient air quality (QCVN05:2013/BTNMT). However, solutions needed to be suggested to improve the air quality for human health and the environment as reducing roadside dust pollution and traffic noise in Ho Chi Minh City. The first priority was the solution of planting trees, which were found along a lane and got different functions. Tree species were suitable for ecological conditions along the roadsides these were applied for green solutions to be planted, including Hopea odorata, Mimusops elengi, Khaya senegalensis and Bougainvillea spectabilis.

Abstract: Although food insecurity (a measure of a household’s availability, accessibility, utilisation, and stability of food) and micronutrient deficiencies have remained a serious public health concern in Nepal, research assessing the association between them is least known. Using data from the 2016 Nepal Multiple Indicators Cluster Survey (NMICS), this cross-sectional study that included a sample of 2143 non-pregnant women aged 15-49 years assessed whether there is an association between household (HH) food insecurity with red blood cell (RBC) folate deficiency and iron-deficiency anaemia. Multivariate analysis was conducted to examine the association between HH food insecurity and Iron-deficiency anaemia (IDA) and RBC folate deficiency. Overall, 56% of participants were from food-secure households, whilst 7% were from severely food-insecure households. In adjusted models, living in a severely food insecure household was significantly associated with both IDA [adjusted odds ratio (AOR): 1.63; 95% confidence interval (CI): (1.02, 2.60)] and RBC folate deficiency [AOR: 3.83; 95% CI: (1.03, 14.18)]. Findings from this study revealed that severe household food insecurity was associated with both IDA and RBC folate. Public health policies to ameliorate IDA and RBC folate should provision for spending on food assistance programmes to address household food insecurity in Nepal. Social protection schemes should be expanded for those belonging to severely food insecure HHs who are unable to feed themselves and produce food for subsistence to strengthen their livelihood and ensure access to adequate, nutritious, and diverse food. Further, Food System needs to be strengthened to increase access to and consumption of nutritious, safe, affordable and sustainable diets. Pro-poor and women-focused food security policies need to be developed.

Abstract: The use of remote sensing data to study the spatial distribution of land surface temperature (LST) and thermal radiation has revealed the negative impact of urban heat islands on human health. As an increase in LST and thermal radiation can have serious health consequences, it is important to constantly evaluate and gather information on the extent of these changes in a given region. Such information is crucial for public health and environmental epidemiology, as it enables emergency response planners and public health specialists to identify the areas most at risk and use scientific findings to improve the health of the affected populations. Remote sensing data from the Landsat Thematic Mapper (LANDSAT 7) image of 2002 and the Operational Land Imager and Thermal Infrared Sensor (LANDSAT 8) images of 2014 and 2018 were utilized to estimate the spatial distribution of land surface temperature and thermal radiation in Owo, Ondo State, Nigeria. The study found that the rapid urbanization and modification of the vegetation cover and natural surfaces in Owo had contributed to an increase in land surface temperature and thermal radiation. The research also noted that areas with low vegetation cover had higher surface temperatures, while areas with high vegetation cover had lower surface temperatures. Additionally, the study found that areas with higher surface temperatures were associated with increased thermal radiation, following a similar pattern to that of the spatial distribution of land surface temperature. In particular, regions with higher land surface temperatures emitted more thermal radiation compared to regions with lower land surface temperatures. The results of this study can provide valuable insights for the public health department of Ondo State in terms of understanding, managing, and taking action to improve the health and well-being of residents, particularly those residing in areas that are most impacted by the urban heat island effect.
