Drug shortages are a multifaceted problem that has been recurring in Saudi Arabia over the past decade with its significant negative impact on patient care. However, there is a dearth of evidence about possible domestic reasons, if any, behind this recurring problem. Recently, the Pharmacy Education Unit at King Saud University College of Pharmacy has called for a meeting with multiple stakeholders from academia, pharmaceutical care, pharmaceutical industry, purchasing and planning, and regulatory bodies to unveil the root domestic causes of the drug shortages in the Kingdom.

Polycyclic aromatic hydrocarbons (PAHs) in street dust pose a serious problem threatening both the environment and human health. Street dust samples were collected from five different land use patterns (traffic areas TRA, urban area URA, residential areas REA, mixed residential commercial areas MCRA and suburban areas SUA) in Jeddah, a Saudi coastal city, and one in in Hada Al Sham, a rural area (RUA). This study aimed to investigate the status, profile, sources of PAHs and estimate their human health risk.

In this study, we investigated the inhibitory effects of -coumaric acid on the glycosylation of proteins in the retinas of diabetic rats. Male rats were divided into two main groups, Group I (normal control) and Group II (diabetic); Group II was further divided into four subgroups: Group IIa (diabetic control), Group IIb (diabetic rats were given -coumaric acid orally [150 mg/kg, body weight (bw)/day]), Group IIc (diabetic rats were given HCA -coumaric acid orally [300 mg/kg bw/day]), and Group IId (diabetic rats were given insulin [10 units/kg bw/day]) as a positive control). The treatment lasted for six weeks, and the data obtained suggested that -coumaric acid reduced glucose and glycated hemoglobin levels, which further decreased the formation of glucose-derived advanced glycation end products.

Objective: To determine changes in post-surgical cavity volume for metastases based on time from surgery, pre-operative tumor dimensions and other predictors, in patients planned for post-operative stereotactic radiosurgery (SRS).

Methods: Patients with resected brain metastases from a primary solid tumor, treated with post-operative surgical cavity SRS from 2008 to 2014 were identified from an institutional prospective database. The segmented three-dimensional (3D) volume of the pre-operative tumor and post-operative surgical cavity were determined based on MRI and percent volume change was calculated.

A few epidemiologic studies suggest that exposure to bisphenol A (BPA) is associated with type 2 diabetes mellitus (T2DM). However, little is known about association between other phenolic endocrine disrupting chemicals (EDCs) and T2DM. In this case-control study, we measured urinary concentrations of 23 phenolic EDCs in 101 individuals from Jeddah, Saudi Arabia, to examine the association of parabens, antimicrobials, bisphenols, benzophenones and bisphenol A diglycidyl ethers with T2DM.

Background/aim: Due to epidemic levels of obesity and type 2 diabetes mellitus (DM), nonalcoholic fatty liver disease (NAFLD) and resulting nonalcoholic steatohepatitis (NASH) will be driving factors in liver disease burden in the coming years in Saudi Arabia and United Arab Emirates (UAE).

Materials And Methods: Models were used to estimate NAFLD and NASH disease progression, primarily based on changes in adult prevalence rates of adult obesity and DM. The published estimates and expert interviews were used to build and validate the model projections.

Background: Studies have shown that Na-K ATPase activity was altered in disrupted red blood cell membranes and this enzyme is believed to be the site of active transport of Na and K in intact red blood cells. The enzyme is often referred to as Na-K pump because it pumps Na out and K into the cell against gradients with the concomitant hydrolysis of intracellular ATP.

Objective: The aim of this study was to find out the possibility of using Na-K-ATPase activity as a biomarker for the diagnosis of individuals with different physiological conditions.

Background: The goal of this study was to analyze the association between the FTO rs17817449 (G>T), G protein beta3 subunit (GNB3) C825T and Melanocortin 4 receptor (MC4R) A822G single nucleotide polymorphism (SNP) with obesity in Saudi subjects.

Methods: The subjects were divided into 2 groups according to BMI: Obese (BMI> 29.9) and non- obese control (BMI<24.

Three new solid complexes of pipemidic acid (Pip-H) with Ru, Pt and Ir were synthesized and characterized. Pipemidic acid acts as a uni-dentate chelator through the nitrogen atom of the -NH piperazyl ring. The spectroscopic data revealed that the general formulas of Pip-H complexes are [M(L) (Cl) ]·HO ((1) M = Ru, L: Pip-H, = 3, = 3, = 6; (2) M = Pt, L: Pip-NH, = 2, = 4, = 0 and (3) M = Ir, L: Pip-H, = 3, = 3, = 6).

Several systems (tumor-node-metastasis [TNM], Barcelona Clinic Liver Cancer [BCLC], Okuda, Cancer of the Liver Italian Program [CLIP], and albumin-bilirubin grade [ALBI]) were developed to estimate the prognosis of patients with hepatocellular carcinoma (HCC) mostly prior to the prevalent use of sorafenib. We aimed to compare the prognostic and discriminatory power of these models in predicting survival for HCC patients treated with sorafenib and to identify independent prognostic factors for survival in this population. Patients who received sorafenib for the treatment of HCC between 1 January 2008 and 30 June 2015 in the provinces of British Columbia and Alberta, and two large cancer centers in Toronto, Ontario, were included.

Purpose: Two dose calculation algorithms are available in Varian Eclipse software: Anisotropic Analytical Algorithm (AAA) and Acuros External Beam (AXB). Many Varian Eclipse-based centers have access to AXB; however, a thorough understanding of how it will affect plan characteristics and, subsequently, clinical practice is necessary prior to implementation. We characterized the difference in breast plan quality between AXB and AAA for dissemination to clinicians during implementation.

Population-based studies are the gold standard to understand the burden of different diseases, plan health care policy and resource allocation, and provide an accurate estimate of disease several disease indices including mortality. However, population-based studies are difficult to undertake in a resource-limited situation where no robust data bases and disease registries are available. Therefore, hospital-based cohorts may be used to inform about the community health.
