The aim of this study was to report the outcomes and prognostic factors for a cohort of patients with osteosarcoma who presented with metastasis at initial diagnosis. Data of consecutive patients with osteosarcoma and metastatic disease at initial presentation, who were treated and followed up at a single institution, were retrospectively reviewed. The effect of potential factors on overall survival (OS) was analyzed through univariate and multivariate analysis. Between January, 2000 and March, 2013, a total of 135 patients with osteosarcoma, of whom 21 (16.0%) had distant metastasis at initial presentation, were diagnosed and treated at our center and were included in this analysis. The patients were treated with a strategy that integrates multi-agent chemotherapy and resection of all sites of gross disease whenever feasible. The 5-year OS and event-free survival (EFS) were 23.0% and 11.0%, respectively. The factors associated with inferior OS in the univariate analysis included the osteoblastic variant, extrapulmonary metastasis and failure to achieve complete remission. In the multivariate analysis, the osteoblastic variant [hazard ratio (HR)=4.83, 95% confidence interval (CI): 1.16-20.0, P=0.038] and extrapulmonary metastasis (HR=5.0, 95% CI: 1.40-17.94, P=0.018) were the only independent prognostic factors. The current outcomes of patients with osteosarcoma and metastasis at initial diagnosis remained poor. The osteoblastic subtype and extrapulmonary metastatic sites predicted poor survival in our series. To the best of our knowledge, this is the first report of the correlation between the histological subtype and survival for patients with metastatic disease at initial presentation; therefore, confirmation in future studies is required.
DD and significant depressive symptoms are common in patients with colon cancer in Saudi Arabia, and are predicted by a distinct set of demographic and psychosocial risk factors that may help with identification. Demographic and psychological risk factors were more likely to be associated with depression than cancer characteristics in this sample.
Substance use disorders (SUDs) patients have longer lengths of hospital stay, and more unplanned readmissions than other hospitalized patients. We aim to evaluate SUD-related rehospitalization and length of hospital stay in a major rehabilitation center that serves countries of the Gulf States. In a retrospective cohort study for 16-year data set in Al-Amal Hospital Electronic Health Record in the city of Dammam, Eastern region of Saudi Arabia, patients received services from the SUD treatment programs in the period of January 1, 2005, to December 31, 2021. We used cause-specific Cox proportional hazards regression model to estimate risk of readmission, and general linear model to examine the association between substance use disorders and length of hospital stay. Of the total cohort, 4398 (30.17%) were readmitted within 1 year of discharge date. More than half of the cohort were unemployed patients (52.93%). Patients diagnosed with amphetamine use disorder were 1.36 higher risk of readmission compared to no amphetamine disorder (HR = 1.36; CI (1.04, 1.78) P.02). Patients diagnosed with mental disorder had 7.25 times higher risk of longer hospital stay compared to no mental health disorder (coefficient = 7.25; P < .0001). Amphetamine use disorder increased the risk of readmission. A secondary diagnosis of mental disorders among SUD patients increased length of hospital stay. As a targeted region of amphetamine smuggling in the world, policy and clinical decision-makers in Saudi Arabia and the Gulf States should consider taking proactive steps to minimize the future anticipated high demand for addiction treatment in the region.
Behavioral addiction is identified as any compulsive, repeated, and persistent behavior that leads to significant and functionally impairing harm or distress. The aim of this study is to determine the prevalence of internet, video-gaming, and pornography addictions among medical students in Western region. In addition, we intend to investigate the relationship between these behavioral addictions with stress and anxiety. Our study was a cross-sectional study with a sample size of 225. The study participants were medical students in their 3rd, 4th, and 5th academic years from five different medical colleges in Western region. The questionnaire included demographics and adapted five different pre-validated scales: Young's Internet Addiction Test – Short Version (IAT-SV), Internet Gaming Disorder Scale 9 – Short Form (IGDS9-SF), (PPC scale), Perceived Stress Scale (PSS), and Generalized Anxiety Disorder 7-item scale (GAD-7). The IAT-SV scale showed: 71 (31.6%) of the participants had normal internet usage, 51 (22.7%) participants showed problematic usage, and 103 (45.8%) used the internet pathologically. The IGDS9-SF scale had observed the following values: 220 participants (97.8%) were non-disordered, and 5 participants (2.2%) were found to be disordered. Statistical analysis showed a highly significant association between stress and problematic pornography consumption (P < 0.01), and internet addiction (P <0.001). Moreover, there was a significant association between anxiety and internet gaming disorder (P < 0.01). This study showed high prevalence of internet addiction and low prevalence of internet gaming disorder. Also, it gave more understanding to a possible association between these behavioral addictions with stress and anxiety.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
