Patterns of psychiatric diagnoses in inpatient and outpatient psychiatric settings in Saudi Arabia

Abstract Objective This study aimed to explore the current patterns of psychiatric diagnoses in inpatient and outpatient psychiatric settings in Saudi Arabia. Methods Cross-sectional study was conducted on patients seeking psychiatric advice at six hospitals in the five main regions of Saudi Arabia. The data were primarily obtained by reviewing patient charts. Results Total of 1,205 patients were recruited. The majority was unemployed (71.4%), had a low level of education (85.5%), and had low income (61.9%). The most common psychiatric diagnoses among inpatients were schizophrenia (55.8%), bipolar disorder (23.3%) and major depressive disorder (7.2%). The most common psychiatric diagnoses among outpatients were major depressive disorder (29.3%), schizophrenia (28.9%), generalized anxiety disorder (15.6%) and bipolar disorder (11.5%). Primary psychotic disorders and secondary psychiatric disorders were significantly more frequent among men whereas primary bipolar disorders and depressive disorders were significantly more frequent among women in both inpatient and outpatient settings. Psychotic and bipolar disorders were significantly more frequent among younger patients whereas depressive disorders were significantly more frequent among older patients; anxiety disorders were of similar frequency in all age groups. Discussion The most common psychiatric diagnoses among inpatients were schizophrenia and bipolar disorder whereas the most common psychiatric diagnoses among outpatients were major depressive disorder and schizophrenia.

Modal and Vibration Analysis of Functionally Graded Dental Implant.

Dental implant is considered to be the best treatment when dealing with the loss of teeth. It gives beautiful results and can last longer than most of other treatments. Since the Osseo-integration period is a critical period for implant stability, so the used material for dental implant is one of the most factors affecting the stability and Functionally Graded Material (FGM) is one of the opportunities to improve it. The aim of this research is to carry out modal analysis and vibration analysis analytically for functionally graded Dental Implant. In this study several models for dental implant was analyzed by ANSYS15.0 APDL. The functionally graded material was considered in three models. The same materials, Ti-HA, where used in all of them but with different ratio in each. The natural frequency and mode shapes were extracted for all models. The frequency responses of functionally graded Dental Implant after performing a static analysis for each modal have been studied. It was noticed using modal analysis that all of the extracted results for FGM are vary between the two basic materials and it is affected by the concentration of each. It is firmly believed that FGM is the future of dental implant due to the ability of designing a specific material property to be more stable. A comparison of the materials that utilized in FGM when the ration of each 100% was performed as well as an evaluation for the classical dental implant. It is firmly believed that FGM is the future of dental implant due to the ability of designing a specific material property to be more stable.
