    OBJECTIVE: To identify commonly reported community-acquired organisms and antimicrobial resistance patterns exhibited by Gram-positive and Gram-negative pathogens among pilgrims visiting emergency care departments in Makkah.
    METHOD: The study was designed as a retrospective audit of all patients (pilgrims) admitted to two hospitals and residing in the city of Makkah, Saudi Arabia.
    RESULTS: Among 374 isolates, Gram-negative pathogens accounted for 280 (75%), while the remaining 94 (25%) were Gram-positive organisms. Among all isolated pathogens, the highest resistance was observed for amoxicillin-clavulanic acid. Klebsiella pneumoniae had the highest resistance to amoxicillin-clavulanic acid and ampicillin. Most of the organisms were sensitive to tobramycin except Acinetobacter baumannii (n=3, 50%), Escherichia coli (n=4, 57%), and K. pneumoniae (n=6, 46%).
    CONCLUSION: Overall, a high resistance was observed for beta-lactam antibiotics. In addition, a high resistance was noted for ceftazidime with A. baumannii species (n=16, 77%). However, for quinolones, the highest resistance to ciprofloxacin was observed for E. coli, A. baumannii, methicillin-resistant Staphylococcus aureus, and K. pneumoniae.

    Reproductive carrier screening started in some countries in the 1970s for hemoglobinopathies and Tay-Sachs disease. Cystic fibrosis carrier screening became possible in the late 1980s and with technical advances, screening of an ever increasing number of genes has become possible. The goal of carrier screening is to inform people about their risk of having children with autosomal recessive and X-linked recessive disorders, to allow for informed decision making about reproductive options. The consequence may be a decrease in the birth prevalence of these conditions, which has occurred in several countries for some conditions. Different programs target different groups (high school, premarital, couples before conception, couples attending fertility clinics, and pregnant women) as does the governance structure (public health initiative and user pays). Ancestry-based offers of screening are being replaced by expanded carrier screening panels with multiple genes that is independent of ancestry. This review describes screening in Australia, Cyprus, Israel, Italy, Malaysia, the Netherlands, Saudi Arabia, the United Kingdom, and the United States. It provides an insight into the enormous variability in how reproductive carrier screening is offered across the globe. This largely relates to geographical variation in carrier frequencies of genetic conditions and local health care, financial, cultural, and religious factors.

    Current practices and available resources for nutrition therapy in paediatric intensive care units (PICUs) in the Asia Pacific-Middle East region are expected to differ from western countries. Existing guidelines for nutrition management in critically ill children may not be directly applicable in this region. This paper outlines consensus statements developed by the Asia Pacific-Middle East Consensus Working Group on Nutrition Therapy in the Paediatric Critical Care Environment. Challenges and recommendations unique to the region are described.

    BACKGROUND: Dengue suppression often relies on control of the mosquito vector, Aedes aegypti, through applications of insecticides of which the pyrethroid group has played a dominant role. Insecticide resistance is prevalent in Ae. aegypti around the world, and the resulting reduction of insecticide efficacy is likely to exacerbate the impact of dengue. Dengue has been a public health problem in Saudi Arabia, particularly in Jeddah, since its discovery there in the 1990s, and insecticide use for vector control is widespread throughout the city. An alternative approach to insecticide use, based on blocking dengue transmission in mosquitoes by the endosymbiont Wolbachia, is being trialed in Jeddah following the success of this approach in Australia and Malaysia. Knowledge of insecticide resistance status of mosquito populations in Jeddah is a prerequisite for establishing a Wolbachia-based dengue control program as releases of Wolbachia mosquitoes succeed when resistance status of the release population is similar to that of the wild population.

    METHODS: WHO resistance bioassays of mosquitoes with deltamethrin, permethrin and DDT were used in conjunction with TaqMan® SNP Genotyping Assays to characterize mutation profiles of Ae. aegypti.

    RESULTS: Screening of the voltage-sensitive sodium channel (Vssc), the pyrethroid target site, revealed mutations at codons 989, 1016 and 1534 in Ae. aegypti from two districts of Jeddah. The triple mutant homozygote (1016G/1534C/989P) was confirmed from Al Safa and Al Rawabi. Bioassays with pyrethroids (Type I and II) and DDT showed that mosquitoes were resistant to each of these compounds based on WHO definitions. An association between Vssc mutations and resistance was established for the Type II pyrethroid, deltamethrin, with one genotype (989P/1016G/1534F) conferring a survival advantage over two others (989S/1016V/1534C and the triple heterozygote). An indication of synergism of Type I pyrethroid activity with piperonyl butoxide suggests that detoxification by cytochrome P450s accounts for some of the pyrethroid resistance response in Ae. aegypti populations from Jeddah.

    CONCLUSIONS: The results provide a baseline for monitoring and management of resistance as well as knowledge of Vssc genotype frequencies required in Wolbachia release populations to ensure homogeneity with the target field population. Vssc mutation haplotypes observed show some similarity with those from Ae. aegypti in southeast Asia and the Indo-Pacific, but the presence of the triple mutant haplotype in three genotypes indicates that the species in this region may have a unique population history.

    On 14 April 2014, the first laboratory-confirmed case of Middle East respiratory syndrome coronavirus (MERS-CoV) infection was reported in Malaysia in a man in his mid-fifties, who developed pneumonia with respiratory distress, after returning from a pilgrimage to Saudi Arabia. The case succumbed to his illness three days after admission at a local hospital. The follow-up of 199 close contacts identified through contact tracing and vigilant surveillance did not result in detecting any other confirmed cases of MERS-CoV infection.

    Aim: This study aimed to assess the cost-effectiveness of starting insulin therapy with biphasic insulin aspart 30 (BIAsp 30) in people with type 2 diabetes inadequately controlled on oral glucose-lowering drugs in Saudi Arabia, India, Indonesia, and Algeria.

    Methods: The IMS CORE Diabetes Model was used to evaluate economic outcomes associated with starting BIAsp 30, using baseline characteristics and treatment outcomes from the A(1)chieve study. Time horizons of 1 and 30 years were applied, with country-specific costs for complications, therapies, and background mortality. Incremental cost-effectiveness ratios (ICERs) are expressed as cost per quality-adjusted life-year (QALY) in local currencies, USD, and fractions of local GDP per capita (GDPc). Cost-effectiveness was pre-defined using the World Health Organization definition of <3.0 times GDPc. Comprehensive sensitivity analyses were performed.

    Results: In the primary 30-year analyses, starting BIAsp 30 was associated with a projected increase in life expectancy of >1 year and was highly cost-effective, with ICERs of -0.03 (Saudi Arabia), 0.25 (India), 0.48 (India), 0.47 (Indonesia), and 0.46 (Algeria) GDPc/QALY. The relative risk of developing selected complications was reduced in all countries. Sensitivity analyses including cost of self-monitoring, treatment costs, and deterioration of glucose control with time showed the results to be robust. In a 1-year analysis, ICER per QALY gained was still cost-effective or highly cost-effective.

    Conclusion: Starting BIAsp 30 in people with type 2 diabetes in the A(1)chieve study was found to be cost-effective across all country settings at 1- and 30-year time horizons, and usefully increased predicted life expectancy.

    Monolluma quadrangula (Forssk.) Plowes is used in Saudi traditional medicines to treat gastric ulcers. The hydroalcoholic extract of M. quadrangula (MHAE) was used in an in vivo model to investigate its gastroprotective effects against ethanol-induced acute gastric lesions in rats. Five groups of Sprague Dawley rats were used. The first group was treated with 10% Tween 20 as a control. The other four groups included rats treated with absolute ethanol (5 mL/kg) to induce an ulcer, rats treated with 20 mg/kg omeprazole as a reference drug, and rats treated with 150 or 300 mg/kg MHAE. One hour later, the rats were administered absolute ethanol (5 mL/kg) orally. Animals fed with MHAE exhibited a significantly increased pH, gastric wall mucus, and flattening of the gastric mucosa, as well as a decreased area of gastric mucosal damage. Histology confirmed the results; extensive destruction of the gastric mucosa was observed in the ulcer control group, and the lesions penetrated deep into the gastric mucosa with leukocyte infiltration of the submucosal layer and edema. However, gastric protection was observed in the rats pre-fed with plant extracts. Periodic acid-Schiff staining of the gastric wall revealed a remarkably intensive uptake of magenta color in the experimental rats pretreated with MHAE compared to the ulcer control group. Immunohistochemistry staining revealed an upregulation of the Hsp70 protein and a downregulation of the Bax protein in rats pretreated with MHAE compared with the control rats. Gastric homogenate showed significantly increased catalase and superoxide dismutase, and the level of malondialdehyde (MDA) was reduced in the rats pretreated with MHAE compared to the control group. In conclusion, MHAE exhibited a gastroprotective effect against ethanol-induced gastric mucosal injury in rats. The mechanism of this gastroprotection included an increase in pH and gastric wall mucus, an increase in endogenous enzymes, and a decrease in the level of MDA. Furthermore, protection was given through the upregulation of Hsp70 and the downregulation of Bax proteins.
