Both α- and β-thalassemia (α- and β-thal) are highly prevalent in the population of the Al-Qatif and Al-Ahsa regions in the Eastern Province of Saudi Arabia. This study provides a more precise picture of the α-thal mutations prevalent in 104 transfusion-dependent β-thal patients in the Eastern Province. Detection of α-thal mutations was carried out using the α-globin StripAssay kit. A total of 12 α-thal mutations (21 genotypes) were identified in 33.7% of the chromosomes (46 patients). The heterozygous and homozygous -α(3.7) (α(+)) deletion mutations were the most prevalent in the β-thal patients (21.7%). We identified three α(0) deletions [- -(MED), - -(FIL) and -(α)20.5] that have not been previously reported for the population of Saudi Arabia. The seven point mutations identified in the β-thal patients were: codon 14 [TGG>TAG (α1)], codon 59 [GGC>GAC (α1)] (Hb Adana), polyadenylation signal site (polyA1) [AATAAA>AATAAG (α2)], codon 142 [TAA>TCA (α2)] (Hb Koya Dora), codon 59 [GGC>GAC (α2)] (Hb Adana), initiation codon [ATG>ACG (α2)] and the ααα(anti 3.7) gene triplication. The Hb Koya Dora mutation occurred at the highest frequency (15.38%). Comparison of the clinical phenotype of β-thal patients, with and without an α-thal mutation, showed that patients with β-thal alone had a significantly elevated level of alanine transaminase (ALT) (mean 72.5 IU/L) and aspartate transaminase (AST) (mean 71.8 IU/L) (p <0.005). In addition, the β-thal patients without an α-thal mutation had a higher percentage of osteoporosis (16.6%), fractures (12.5%), and splenectomies (58.3%). This confirms previous data that the co-inheritance of α-thal in β-thal patients results in the amelioration of the clinical phenotype of β-thal patients. Moreover, the high frequency of α- and β-thal in the Eastern Province of Saudi Arabia and their coinheritance, necessitates the inclusion of α-thal testing in the current pre marital testing program to highlight the risk to the offspring of affected individuals.

This study aimed to investigate whether the use of protection devices and attitudes of interventional professionals (including radiologists, cardiologists, vascular surgeons, medical imaging technicians and nurses) towards radiation protection will differ between Saudi Arabian and Australian hospitals. Hard copies of an anonymous survey were distributed to 10 and 6 clinical departments in the Eastern province of Saudi Arabia and metropolitan hospitals in Western Australia, respectively. The overall response rate was 43 % comprising 110 Australian participants and 63 % comprising 147 Saudi participants. Analysis showed that Australian respondents differed significantly from Saudi respondents with respect to their usages of leaded glasses (p < 0.001), ceiling-suspended lead screen (p < 0.001) and lead drape suspended from the table (p < 0.001). This study indicates that the trained interventional professionals in Australia tend to adhere to benefit from having an array of tools for personal radiation protection than the corresponding group in Saudi Arabia.

We report here the main characteristics of ‘Arabia massiliensis’ strain Marseille-P3078(T) gen. nov., sp. nov., ‘Gordonibacter massiliensis’ Marseille-P2775(T) sp. nov. and ‘Bacilliculturomica massiliensis’ strain Marseille-P3303 gen. nov., sp. nov. The culturomics approach combined with taxonogenomics was used to characterize these strains, which were all isolated from a faecal specimen of a 50-year-old Saudi Bedouin woman.

We report here the main characteristics of ‘Blautia phocaeensis’ strain Marseille-P3441 sp. nov. and ‘Lachnoclostridium edouardi’ strain Marseille-P3397 sp. nov., that were isolated from a faecal specimen of a 42-year-old female Saudi Bedouin. We used a bacterial culturomics approach combined with taxono-genomics.

Sickle cell disease (SCD) is quite common in eastern Saudi Arabia and Avascular necrosis of femoral head (ANFH) occurs in 30% of the young patients leading to early joint arthroplasty. This study was conducted to assess the benefits of injection of osteoblasts in the avascular lesions of the head of femur.
