Risk factors for ADHD and comorbid psychiatric, academic and behavior problems among primary school students in Jeddah, Saudi Arabia.

Risk factors for attention deficit hyperactivity disorder (ADHD), psychiatric, and classroom academic/behavioral problems were examined in 929 students grades 1-6 in Jeddah, Saudi Arabia. Teachers identified ADHD by completing the Vanderbilt ADHD scale. Compared to controls without ADHD, students with ADHD were more likely to have early parental loss, head trauma, motor/language delay, family psychiatric problems, and high family stress.

Carbonated soft drinks alter hepatic cytochrome P450 isoform expression in Wistar rats.

The aim of the current study was to examine the effects of chronic consumption of soft drinks (SDs) on hepatic oxidative stress and cytochrome P450 enzymes (CYPs) expression in the livers of Wistar rats. For 3 consecutive months, the rats had free access to three different soft drinks, Coca-Cola, Pepsi-Cola and 7-UP. The rats were subsequently compared with control group rats that had consumed water.

New host/parasite record for very rare chewing louse Cuculotogaster arabicus (Clay, 1938) (Phthiraptera: Ischnocera) on endemic mountain partridges of Arabian Peninsula.

The endemic avifauna of Arabia is unique and characteristic through the whole region. Little is known about these birds and their ectoparasites. The Arabian partridge Alectoris melanocephala (Rüppell, 1835) and Philby's partridge Alectoris philbyi Lowe, 1934 are two endemic species which are distributed through the Sarawat Mountains in Saudi Arabia and Yemen.

The prevalence and the clinical characteristics of metabolic syndrome patients admitted to the cardiac care unit.

Objectives: Metabolic syndrome (MetS) is a group of multiple cardiovascular risk factors, including dysglycemia, central obesity, high cholesterol, and hypertension. Cardiovascular disease is one of the most common complications of MetS. Recent studies showed that prevalence of MetS among patients admitted with acute coronary syndrome was as high as 46%.

Little known chewing lice (Phthiraptera) infesting crab plover Dromas ardeola Paykull, 1805 (Charadriiformes: Dromadidae) from the Red Sea.

Scanty information is available for many species of chewing lice of marine birds. Through this work we investigated one of most characteristic marine bird for chewing lice. Seven individuals of crab plovers Dromas ardeola Paykull, 1805 were trapped using standard mist nets on Humr Island in Farasan Archipelago, Saudi Arabia.

New records of species of Saemundssonia (Insecta: Phthiraptera: Philopteridae) infesting breeding terns in the Arabian Peninsula, with notes on their phylogeny and ecology.

Six species of terns, which breed on the Arabian Peninsula, were examined for head chewing lice of the genus Saemundssonia in four different islands around the coasts of Saudi Arabia, both in the Red Sea and in the Arabian Gulf. Four louse species were collected: Saemundssonia laticaudata, Saemundssonia melanocephalus, Saemundssonia meridiana and Saemundssonia sternae, of which three are recorded for the first time from this region. Also, we record three new host-louse associations for the world-Saemundssonia laticaudata and Saemundssonia sternae from white-cheeked terns and Saemundssonia melanocephalus from Saunders's terns-including a host-switch event of Saemundssonia laticaudata on white-cheeked terns in the Karan Island population.

Chewing lice (Phthiraptera: Amblycera, Ischnocera) from Red Sea gulls with new host-parasite records.

Knowledge about chewing lice from marine birds of the Red Sea is minimal. Five species of gulls were examined for chewing lice in three different localities of the Saudi Arabian Red Sea coast. Two gull species were examined for lice for the first time (Larus armenicus Buturlin, 1934 and Larus michahellis Naumann, 1840) and their lice represent new host-louse associations.
