Surgical site infection (SSI) is disastrous in orthopedic practice as it is difficult to rid the bone and joint of the infection. This study was aimed to assess the prevalence of SSI in orthopedic practice and to identify risk factors associated with surgical site infections. All patients admitted to the orthopedic male and female wards between January 2006 and December 2011 were included in the study group. The data, which were collected from the medical charts and from the QuadraMed patient filing system, included age, sex, date of admission, type of admission (elective versus emergency), and classification of fractures. Analyses were made to find out the association between infection and risk factors, the χ2 test was used. The strength of association of the single event with the variables was estimated using Relative Risk, with a 95% confidence interval and P < 0.05. A total of 79 of 3096 patients (2.55%) were included: 60 males and 19 females with the average age of 38.13 ± 19.1 years. Fifty-three patients were admitted directly to the orthopedic wards, 14 were transferred from the surgical intensive care unit, and 12 from other surgical wards. The most common infective organism was Staphylococcus species including Methicillin Resistant Staphylococcus aureus (MRSA), 23 patients (29.11%); Acinetobacter species, 17 patients (21.5%); Pseudomonas species, 15 patients (18.9%); and Enterococcus species, 14 patients (17.7%). Fifty-two (65.8%) had emergency procedures, and in 57 patients trauma surgery was performed. Three (3.78%) patients died as a result of uncontrolled septicemia. SSI was found to be common in our practice. Emergency surgical procedures carried the greatest risk with Staphylococcus species and Acinetobacter species being the most common infecting organisms. Proper measures need to be undertaken to control infection rates by every available method; antibiotics alone may not be sufficient to win this war.

The relationship between language anxiety and self-determined motivation has been examined from various aspects in the applied linguistics domain. However, the direction of the relationship tend to disagree. Some studies report positive correlation whereas others (and in most cases) show negative correlation. To address this issue, the present study attempted to evaluate in depth the relationship between these two variables. We first qualitatively examined the types of language anxiety students face during learning, and then assessed how motivational variables based on self-determination theory can predict these identified types of anxiety. The results showed that sense of competence and relatedness negatively predicted certain types of anxiety while controlled motivation positively predicted only the general language anxiety. However, perception of autonomy and autonomous motivation did not predict any sub-types of language anxiety while sense of relatedness positively predicted psychological anxiety. The findings are discussed in terms of their theoretical and educational implications for language learning.

IntroductionVaso-occlusive crisis (VOC) episodes are considered to be the cause of 95% of hospitalizations for sickle cell disease (SCD) patients. The frequency of VOC is significantly associated with higher or lower lactate dehydrogenase levels, higher hemoglobin concentration, higher white blood cell, and neutrophil count, and lower platelet counts. In this study, we highlighted the association and predictors of VOC episodes in Saudi Arabia. MethodsThis is a retrospective observational study that was conducted in a period from January 2018 to December 2019 which included patients who were admitted and treated as sickle cell disease patients were included in this study. Retrieved data included patients' age, sex, and other demographic data items as well as the clinical history of SCD. The patients were divided into two groups. Those patients who developed one or two VOC episodes in the period between 2018-2019 were considered mild in severity and patients who developed three or more VOC episodes in the period between 2018-2019 were categorized as moderate to severe. ResultsA total of ninety-four patients (58 males and 36 females) with a male to female ratio of 1.6 were included in this study. The prevalence of patients who had severe vaso-occlusive crisis was 39.4% while mild-moderate were detected among 60.6% of the patients. It was found that there was no significant difference between the frequency of vaso-occlusive crisis and all the hematological parameters (all p>0.05). It was found that the risk of having vaso-occlusive crisis for those patients who were admitted more than three times was 30 times higher than those patients who were admitted by three times or less [adjusted odds ratio (AOR) = 30.081; 95% confidence interval (CI) = 8.204 -110.3; p<0.001)]. ConclusionIt was found that those patients who had three times VOC episodes in our studied period are more liable to have frequent episodes in the future which might necessitate urgent intervention for these patients.
