Anaerobic digestion is a process by which microorganisms break down biodegradable material in the absence of oxygen. The process involves hydrolysis, acidogenesis and methanogenesis stages. Anaerobic digestion of food waste has been widely investigated for biogas recovery but limited study was performed on phosphorus recovery, which is reported depleting. Food waste is produced every day and dumped on landfill for final disposal which may lead to environmental issues such as odour problems and greenhouse gases release, due to decomposing of food waste, hence impacts global climate change. In anaerobic digestion pH is a very crucial parameter in an attempt to recover phosphorus as it highly influences the production of organic acids during acidogenesis.
Probiotics are live, microbial cells with several beneficial health effects on humans. The beneficial effect of probiotics mainly depends on their survival in the gastrointestinal tract. The health-promoting properties of certain LAB inhabiting the human gastrointestinal tract encouraged the food industry to develop new functional food products containing probiotic. Selection of a microbial strain for the incorporation into food products requires both in vitro and in vivo evaluations
Globally, 998 million tonnes of agricultural waste is produced per year and in Malaysia, 1.2 million tonnes of agricultural waste is disposed of into landfills annually. Concurrently, increasing demands of concrete leads to vary of research conducted on improving cement production methods and formulating reduction or eliminate CO2 emissions.
Waste materials from the agricultural and industries can cause problems to human health and the environment when improperly disposed and managed. Due to rapid development in construction, the demand of cement in concrete has increased dramatically. Therefore, wastes such as rice husk, eggshell, glass, fly ash and many more can be used in construction industry to minimize the environmental impact and producing new material on construction industry. Many studies have been conducted as an effort to find replacement materials to substitute cement in concrete.

Chest radiography, or chest X-ray (CXR), is not only an important tool for triaging and screening for pulmonary tuberculosis (TB) but is also useful in aiding diagnosis when pulmonary TB cannot be confirmed bacteriologically. Sabah is a state with high TB burden with the incidence rate of 124/100,000 population in 2015. Access to chest radiography is limited in many settings in Sabah. In 2016, the TB and Leprosy Control Unit of Sabah State Health Department started systematic screening for TB with the help of a mobile digital X-ray unit.

Childhood obesity poses global public health threat and has risen to an alarming level throughout the world. Environmental factors, lifestyle preferences and culture play important roles in the rising prevalence of obesity worldwide. Overweight children are more likely to be overweight or obese in their adulthood and therefore are at greater risk of developing heart disease, diabetes, and other chronic ailments. Children occasionally become overweight on account of medical or genetic conditions. The main cause relates to poor dietary habits, inactivity or a combination of these factors. These situations also pose an emerging public health issue in Asia.
In Malaysia nasopharyngeal carcinoma (NPC) is ranked as number fourth (5.2%) from all cancer and third (8.4%) most common cancer among male population. Nasopharyngeal carcinoma in Malaysia mostly occurs among Chinese (49%), followed by natives of Sabah and Sarawak (28%) and Malay (22%). There were multiple researches done to determine the risk factors for nasopharyngeal carcinoma and most of them from western pacific region. Prevalence of nasopharyngeal carcinoma in Sabah in 2013 is about 106 cases while in 2012 is 75 cases. It shows almost 30% increment from previous year. A total of 53 patients were diagnosed NPC in 2013 from Kota Kinabalu locality and it contributes more than 50% from total prevalence NPC in 2013. NPC is common in local Sabahan, especially in Kadazan and Dusun ethnicity. In 2013, the youngest are 11 years old and the eldest are 84 years old. The upward trend of NPC cases in younger age group is worrisome for us. Thus it is very important to determine the risk factors associated with NPC and this would help the health provider and other stakeholders to do planning in prevention of NPC such as awareness programme or cancer screening for the target high risk group especially for Sabah population.

Dengue is a viral infection caused by four types of viruses (DENV-1, DENV- 2, DENV-3, DENV-4) and transmitted through the bite of infected Aedes aegypti and Aedes albopictus female mosquitoes that feed both indoors and outdoors during the daytime (from dawn to dusk). These mosquitoes thrive in areas with standing water, including puddles, water tanks, containers and old tyres. There were a total of 35 dengue outbreaks under PKK KK with four active outbreaks in the year 2017. One uncontrolled outbreak occurred at Ibu Pejabat Kontigen (IPK) Kota Kinabalu from 16 November 2017 to 21 December 2017.
Dengue fever and its fatal complications have made a comeback since its control in the 1990’s. The Flavivirus has evolved into 4 serotypes DEN 1,2,3,4 which can be passed on by the mosquitoes for 7 generations for each serotype. This communicable disease is predominantly confined to urban areas. Quick control of the spread of the disease will prevent it from becoming an epidemic. The two species mosquitoes involved have different behaviours. The Aedes aegypti is an indoor vector which breeds in clean, clear and calm freshwater. The Aedes albopictus is an outdoor breeding mosquito which breeds in stagnant waters. Surveillance of the areas prone to outbreaks is vital. One of the roles of the entomologist is to monitor the vector for resistance to the insecticides. Localities that have been subjected to recurrent outbreaks will have vector which develop resistance to the insecticides used.
There is a strong need to reduce costs of hospital and advocating health economics in countries like the United States of America. The rising cost of healthcare globally especially in the United States of America has interestingly outraged the temper of many citizens about the Obamacare and Trumpcare. The issue about high cost in healthcare is the failure for people globally to recognize that healthcare facility is a 24-hour round-the-clock service. It therefore involves doubling of the utility bills, tripling the manpower due to shifts and rest, wear-and-tear of basic electrical devices is short-lived, breakdown period of huge machine is consistently due to overloaded usages in the government hospitals and poor knowledge of the maintenance programme. Low birth weights (LBW) is a public health concern because it has a well-known predisposition to increased risk for perinatal infections, respiratory distress and ultimately mortality. There is also a higher risk of poor health outcomes throughout the life course of the LBW newborns that includes Type 2 diabetes, high blood pressure, neurodevelopmental disabilities and cardiovascular diseases. The World Health Organization and United Nations Child’s Fund estimate the prevalence of low birth weights in the world ranges from 3% to 32%. Albania in the year 2000 recorded prevalence of low birth weight of 3% whereas Yemen recorded a low birth weight of 32% in 1997. In 2015, the US national vital statistics pointed out that 83.9% of preterm birth (PTB) are LBW. This indicates that prevention of PTB will lead to a decrease in the incidence of LBW.

Background: Malaysia has been ranked the fattest country in Southeast Asia. Overweight and obesity are the fifth leading risk factor for death globally in 2008. It may lead to increase of risk of non-communicable diseases such as cardiovascular diseases, diabetes, cancer and hypertension.
Objectives: This research aimed to determine the prevalence of overweight and association of overweight with sociodemography, lifestyle as well as its health related conditions of adults in Kampung Tiga Papan.
Methods: Cross-sectional analytical study was used to achieve our specific objectives. A total of 199 adults aged 18 years and above in Kampung Tiga Papan had been recruited by non-probability sampling method. Sociodemographic data and lifestyle adopted were obtained via validated questionnaire, the BMI status of respondents were calculated, blood pressure was measured and DASS-21 score was used to assess mental health of the respondents.
Results: There are 118 (59.3%) respondents categorized into overweight group (BMI>23 kg/m2) and 130 (65.3%) respondents are having abdominal obesity (Waist-hip ratio: male>0.9 and female>0.8). There are significant association between gender, household-income, alcohol status and preference of food and BMI status. Besides, there are significant association between gender, household income, alcohol and smoking status and significant increased risk of hypertension in overweight group.
Conclusion: Overweight is associated to some sociodemographic and lifestyle factors. It helps to target high risk population and community intervention can be done to reduce the prevalence of overweight
Some call it climate change and some global warming, regardless of the term used, it has been deemed the biggest global health threat of the 21st century. It is the 13th goal of United Nations Sustainable Developmental Goals (SDG). Multiple factors contribute to this global phenomenon including the anthropogenic causes which are man-made. The repercussions of this crisis are vast and bring effect environmentally and socioeconomically. These then ultimately lead towards an effect on individual as well as population health.

Melioidosis is a tropical infectious disease cause by gram-negative bacterium, Burkholderia pseudomallei. It is predominantly in tropical climate especially Southeast Asia and Northern Australia. This disease is associated with significant mortality due to early onset of sepsis.
Over the last few years, Universiti Malaysia Sabah (UMS) as part of its global marketing initiative opened its doors to international students to take up elective as well full time programmes. In September 2017, 36 nursing students from a university in China completed a 12-week elective /mobility programme in UMS.
Infectious disease remains a public health concern in Malaysia. Efficient public health infectious disease surveillance is needed in order to address the issues posed by infectious disease. The main goal of public health infectious disease surveillance is to facilitate the control and prevention of the infectious diseases. For that, infectious disease surveillance needs involvement of multidiscipline either in government or non-government/private to ensure its success. General practitioners (GPs) have an important role in public health infectious disease surveillance considering their role and position as one of the main front liner medical personnel.
