RESUMO
Background: Data regarding the effectiveness of antibiotic-loaded bone cement (ALBC) in preventing prosthetic joint infections (PJI) after total joint arthroplasty (TJA) is inconsistent. The objective of this study was to evaluate if the routine use of ALBC influenced the risk of revision surgery due to PJI. Methods: This is a retrospective cohort study performed between January 2018 and September 2020. Adult patients aged ≥ 18 years who underwent TJA (knee or hip) and received either ALBC or plain cement (PC) were included. The outcome of this study was the rate of revision due to PJI. Multivariate analysis using logistic regression was used to identify factors that may be associated with increased risk of PJI, using STATA 15.1 (StataCorp LP, College Station, Texas, USA). Results: A total of 844 patients were screened and 319 patients were included. There were 247 patients in ALBC group and 72 patients in the PC group. Only vancomycin powder was used in all ALBC cases, with a 2 g dose in 50% of the cases (dose ranged between 1 g and 8 g). The status of the prosthetic joint was assessed and recorded up to 2 years of the TJA. Overall, the difference in the rates of PJI between the two groups after primary arthroplasty was not statistically significant (5.6% vs 1.4%; p = 0.173; OR, 4.2; 95% CI, 0.5-33). Conclusion: ALBC was not associated with a reduction in PJI rates after primary TJA. More research is needed to further evaluate the effectiveness of ALBC in preventing PJI.
RESUMO
Antimicrobial resistance (AMR) is a well-recognized global threat. The World Health Organization (WHO) issued a report ranking the critical types of bacterial resistance that need to be monitored. Several studies from individual institutions in Saudi Arabia have reported rates of antimicrobial resistance using automated methods. However, no national surveillance study has been conducted to date using gold standard methods for antimicrobial susceptibility testing. This review summarizes AMR rates for major bacterial pathogens in Saudi Arabia and provides a justification for the need for a national surveillance project. In Saudi Arabia, AMR rates for both Gram-positive and Gram-negative bacteria are on the rise. Surveillance studies help identify AMR trends and emergence of outbreaks. The WHO has started a program, the Global Antimicrobial Resistance Surveillance System (GLASS), encouraging its member states, including Saudi Arabia, to conduct antimicrobial surveillance studies to estimate AMR rates worldwide. Of the microbiological methods used to test antimicrobial susceptibility, only broth microdilution (BMD) is considered the "gold standard." As AMR studies in Saudi Arabia are sparse, mostly limited to single centers and were conducted using automated methods, a national AMR surveillance project is needed to evaluate the current status and to inform stewardship decisions.
RESUMO
BACKGROUND: Excessive and inappropriate antimicrobial use in the community is one risk factor that can result in the spread of antimicrobial resistance. Upper respiratory tract infections are most frequently reported among children and mainly of viral origin and do not require antibiotics. We have conducted Knowledge, Attitude and Perception (KAP) survey of parents to explore the parent's knowledge, attitude & perception of Saudi parents. METHODS: A knowledge attitude perception questioner was adopted from a previous study conducted in Greece by Panagakou et al. Raosoft online sample size calculator calculated the sample size by adding the total estimated Makkah population of 5,979,719 with a response rate of 30%, 5% margin of error and 99% confidence interval. Based on the described criteria five hundred & fifty-eight was the required sample size of the study. Incomplete questioners were excluded from the statistical analysis. SPSS version 21 was used to analyse data and to produce descriptive statistics. RESULTS: Most of the mothers (95%) responded among parents. 67% had no health insurance to cover medications costs. Most of them (74%) were related to medium income level. Seventy per cent of the parents believed physicians as a source of information for judicious antibiotics use. Interestingly, only 8% were agreed that most of the upper respiratory tract infections are caused by viral reasons. Majority of Saudi parents (53%) expect pediatricians to prescribe antimicrobials for their children for symptoms like a cough, nose discharge, sore throat and fever. Moreover, most the parents had the poor knowledge to differentiate commonly used OTC medications for URTI and antibiotics like Augmentin (Co-amoxiclav), Ceclor (cefaclor) and Erythrocin (Erythromycin). While comparing males and female's knowledge level, few males have identified Amoxil (Amoxicillin). Similarly, parents of age 20-30 years have good knowledge about the antibiotics. CONCLUSIONS: Majority of Saudi parents believe in pediatricians and use antibiotics on physician's advice. Most of them expect antibiotics from their physicians as a primary treatment for upper respiratory tract infections. There is need for more educational activities to parents by the pharmacists to prevent antibiotics overuse among children.
