REVIEW
Sumaya Rahman, Hatem Zayed
The GCC is an economic alliance of six Arab countries, including Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and United Arab Emirates (UAE). The rate of endogamous marriage among the GCC countries is approaching 100%, with very high consanguineous marriage rates. Although breast cancer is on the rise in the GCC countries, there are dearth of studies reporting on the genetic epidemiology of breast cancer. In this study, we investigated the frequency of BRCA1/2 and non-BRCA1/2 mutations in breast cancer patients in the GCC countries...

OBJECTIVE: Despite growing endovascular experience within the vascular surgery community, some catheter-based interventions - such as uterine artery embolization (UAE) - remain outside the clinical scope of most vascular surgeons, owing in part to established referral patterns and limited awareness among referring colleagues. We present our experience with a vascular surgery-based, multidisciplinary UAE program at an academic tertiary referral center. METHODS: In a collaborative effort between vascular surgery and gynecology, a Pelvic Vascular Disease Program has been established to provide palliative, prophylactic, and therapeutic embolizations including, but not limited to, UAE...

Picobirnavirus (PBV) is recognized as a putative cause of diarrhea and respiratory illnesses. Although PBV has been reported in several mammalian (including humans) and avian host species, data pertaining to its presence in small ruminants are limited. We report, here, PBV infection in small ruminants (ovine and caprine), in India. From January 2015 to December 2017, 400 samples were tested for the presence of PBV, using an RT-PCR assay specific for the genome segment-2. The overall rate of PBV infection was 35...

Background: The incidence of morbidly adherent placenta, including placenta percreta, has increased significantly over recent years due to rising caesarean section rates. Historically, abnormally invasive placenta has been managed with caesarean hysterectomy; however nonsurgical interventions such as uterine artery embolisation (UAE) are emerging as safe alternative management techniques. UAE can be utilised to decrease placental perfusion and encourage placental resorption, thereby reducing the risk of haemorrhage and other morbidities...

Climate change-reflected in significant environmental changes such as warming, sea level rise, shifts in salinity, oxygen and other ocean conditions-is expected to impact marine organisms and associated fisheries. This study provides an assessment of the potential impacts on, and the vulnerability of, marine biodiversity and fisheries catches in the Arabian Gulf under climate change. To this end, using three separate niche modelling approaches under a 'business-as-usual' climate change scenario, we projected the future habitat suitability of the Arabian Gulf (also known as the Persian Gulf) for 55 expert-identified priority species, including charismatic and non-fish species...
