BACKGROUND: Transmission of dengue virus (DENV) through blood transfusion has been documented and hence screening for DENV during blood donation has been recently recommended by the American Association of Blood Banks and Centres of Disease Control and Prevention. DENV is endemic in the Western province of the Kingdom of Saudi Arabia (KSA) and serotypes 1, 2 and 3, but not 4, have been detected. However, little is known regarding the rates of DENV during blood donation in the kingdom...

MERS-CoV infection emerged in the Kingdom of Saudi Arabia (KSA) in 2012 and has spread to 26 countries. However, 80% of all cases have occurred in KSA. The largest outbreak outside KSA occurred in South Korea (SK) in 2015. In this report, we describe an epidemiological comparison of the two outbreaks. Data from 1299 cases in KSA (2012-2015) and 186 cases in SK (2015) were collected from publicly available resources, including FluTrackers, the World Health Organization (WHO) outbreak news and the Saudi MOH (MOH)...

In the Kingdom of Saudi Arabia (KSA) and Gulf region, a very small amount of municipal solid waste (MSW) is treated for compost production. The produced compost through traditional methods of compost piles and trenches does not coincide with the international standards of compost quality. Therefore, in this study, a continuous thermophilic composting (CTC) method is introduced as a novel and efficient technique for treating food waste into a quality compost in a short period of time. The quality of the compost was examined by degradation rates of organic matter (OM), changes in total carbon (TC), ash contents, pH, dynamics in ammonium nitrogen (NH4-N) and nitrate nitrogen (NO3-N), and nitrification index (NI)...

BACKGROUND: Approximately, 80% of the many cases of the Middle East respiratory syndrome coronavirus (MERS-CoV) confirmed worldwide were diagnosed in the Kingdom of Saudi Arabia (KSA). The risk of the disease spreading internationally is especially worrying given the role of KSA as the home of the most important Islamic pilgrimage sites. This means the need to assess Arab pilgrims' awareness of MERS-CoV is of paramount importance. MATERIALS AND METHODS: A cross-sectional study was carried out during Ramadan 2015 in the Holy Mosque in Makkah, Saudi Arabia...

BACKGROUND: Adverse Childhood Experiences (ACEs) have been linked to an increased risk of health and social problems throughout life. Studies on gender differences from developing countries are scarce. In this paper, we will examine gender variations in the types of reported ACEs and gender-specific relationships between cumulative ACEs and physical and mental health, and Risky Health Behaviors (RHB) in adulthood in the Kingdom of Saudi Arabia (KSA). METHODS: A cross sectional national study was conducted in all of the 13 regions in KSA in 2013 using the ACE- International Questionnaire (ACE-IQ)...

This paper evaluates the performance of direct interface circuits (DIC), where the sensor is directly connected to a microcontroller, when a resistive sensor subjected to dynamic changes is measured. The theoretical analysis provides guidelines for the selection of the components taking into account both the desired resolution and the bandwidth of the input signal. Such an analysis reveals that there is a trade-off between the sampling frequency and the resolution of the measurement, and this depends on the selected value of the capacitor that forms the RC circuit together with the sensor resistance...

BACKGROUND AND AIM: Smokeless tobacco (ST) use is a major cause of cytological changes in the oral mucosa. ST products, such as shamma, which is prevalent in southern Saudi Arabia, raise concerns about the adverse health effects among its users. We evaluated the cytological changes in the oral mucosa of users and nonusers of shamma in the city of Najran, using Papanicolaou staining. MATERIALS AND METHODS: We designed questionnaires and consent forms for this study that were administered to a total of 397 participants, comprising 250 nonusers of shamma (controls) and 147 shamma users (cases)...

The hamadryas baboon (Papio hamadryas hamadryas) is the only indigenous species of non-human primates (NHP) found in the Kingdom of Saudi Arabia (KSA). There are no peer-reviewed publications on viral infections of the baboons of KSA. Apart from camels, other animals are likely sources of the novel Middle East Respiratory Syndrome coronavirus (MERSCoV) for humans. We investigated evidence of highly pathogenic coronavirus infections including MERSCoV in a large group of commensal baboons accompanied by feral dogs, on the outskirts of Ta'if city, KSA, in February 2013...
