Effect of layer thickness on the elution of monomers from two high viscosity bulk-fill composites: A high-performance liquid chromatography analysis.

Aim: The aim is to evaluate the effect of different layer thickness on the amount of elution of monomers from two high viscosity bulk-fill composites after 24 h and 1 month storage in ethanol using high-performance liquid chromatography (HPLC) analysis.

Materials And Methods: Forty-eight samples prepared from two high viscosity bulk-fill composite resins; Tetric EvoCeram Bulk Fill and x-tra fil were divided into three groups ( = 8) based on their layer thickness, i.e.

The trend of feminization of doctors' workforce in Oman: is it a phenomenon that could rouse the health system?

Background: Participation of women in the medical profession over several countries worldwide was increased over the past decades. This paper is a part of ongoing studies aiming at addressing the issue of health workforce feminization among doctors in the Sultanate of Oman as well as exploring the health system readiness in dealing with this phenomenon.

Methods: Literature in addition to reports and records of the Ministry of Health, Oman (MoH), Sultan Qaboos University (SQU) and Oman Medical Specialty Board were reviewed regarding the gender of the doctors and the medical students.

Validation of public health competencies and impact variables for low- and middle-income countries.

Background: The number of Master of Public Health (MPH) programmes in low- and middle-income countries (LMICs) is increasing, but questions have been raised regarding the relevance of their outcomes and impacts on context. Although processes for validating public health competencies have taken place in recent years in many high-income countries, validation in LMICs is needed. Furthermore, impact variables of MPH programmes in the workplace and in society have not been developed.

Strengthening human resources for health through information, coordination and accountability mechanisms: the case of the Sudan.

Problem: Human resources for health (HRH) in the Sudan were limited by shortages and the maldistribution of health workers, poor management, service fragmentation, poor retention of health workers in rural areas, and a weak health information system.

Approach: A "country coordination and facilitation" process was implemented to strengthen the national HRH observatory, provide a coordination platform for key stakeholders, catalyse policy support and HRH planning, harmonize the mobilization of resources, strengthen HRH managerial structures, establish new training institutions and scale up the training of community health workers.

Local Setting: The national government of the Sudan sanctioned state-level governance of the health system but many states lacked coherent HRH plans and policies.
