Pathogenic spectrum of blood stream infections and resistance pattern in Gram-negative bacteria from Aljouf region of Saudi Arabia.

ABSTRACT:

Background

The pathogenic spectrum of bloodstream infections (BSIs) varies across regions. Monitoring the pathogenic profile and antimicrobial resistance is a prerequisite for effective therapy, infection control and for strategies aimed to counter antimicrobial resistance. The pathogenic spectrum of BSIs in blood cultures was analysed, focusing on the resistance patterns of Acinetobacter baumannii, Escherichia coli, and Klebsiella pneumoniae, in Aljouf region.

Methods

This descriptive cross-sectional study analysed the culture reports of all non-duplicate blood samples collected from January 1 to December 31, 2019. Antibiograms of A. baumannii, E. coli, and K. pneumoniae were analysed for antibiotic resistance. The frequency and percentages of multi-drug, extensively-drug, pan-drug and carbapenem resistance were calculated.

Results

Of the 222 bloodstream infections, 62.2% and 36.4% were caused by gram-negative and gram-positive bacteria, respectively. Most BSIs occurred in patients aged ≥60 years (59.5%). Among the 103 isolates of the studied Gram-negative bacteria (GNB), 47.6%, 38.8%, and 2.9% were multi-drug, extensively drug and pan-drug resistant respectively. 46% of K. pneumoniae isolates were carbapenemase producers. Resistance to gentamycin, 1st-4th generation cephalosporins, and carbapenems was observed for A. baumannii. More than 70% of E. coli isolates were resistant to 3rd- and 4th-generation cephalosporins. Klebsiella pneumoniae presented a resistance rate of >60% to imipenems.

Conclusions

Gram-negative bacteria dominate BSIs, with carbapenem-resistant K. pneumoniae most frequently detected in this region. Resistant GNB infections make it challenging to treat geriatric patients. Regional variations in antimicrobial resistance should be continually monitored.

Project description:(1) Backgrounds and Objectives: with the rapid alteration in the socio-demographic pattern of the Saudi community, particularly the changes concerned with women's education and work force, contraceptive use must be a fundamental aspect in the life of women in reproductive age. The present study aimed to identify the prevalence and correlates of contraceptive use among women attending primary health centers in Aljouf region, Saudi Arabia, and to determine the perceived barriers of stopping or not using contraceptive methods in this population. (2) Methods: a primary health center-based cross-sectional study was conducted among 369 women of reproductive age. Data collection was done by using structured questionnaires distributed during face to face interviews with the participants. Data were analyzed using the SPSS program, version 24. (3) Results: most of the participants (n = 166; 45%) were current contraceptive users and 32.2% (n = 119) reported previous use of contraceptive methods. Pills were the most frequently used method (n = 203; 71.2%) and intrauterine devices (IUDs) came next (n = 67; 23.5%) while surgery was the least common method among the respondents (n = 3; 1.1%). Logistic regression analysis showed that the significant predictors of contraceptive use were: age > 35 years (odds ratio (OR): 4.52; confidence interval (CI): 1.56-15.42), Children number ? 4 (odds ratio (OR): 1.41; confidence interval (CI): 1.06-1.92) and monthly income ? 5000 Saudi Riyal (RS) (odds ratio (OR): 2.29; confidence interval (CI): 1.24-8.27). The most perceived barriers towards contraceptive utilization were cultural, demographic, medical, administrative, and barriers related to the method itself. The least reported barriers were psychosocial and physical. (4) Conclusions: the present study showed a high prevalence of contraceptive use among Saudi women in Aljouf region, Saudi Arabia. The study recommended sustained efforts to increase population awareness of the importance of family planning. Policymakers should discover the barriers that prevent contraceptive utilization by women.

Project description:ObjectiveTwitter as a social media platform has revolutionized the way we interact with others and receive information. The presence of dental schools in Twitter facilitates the engagement of students, educators, dental professionals, and the community. Given the explosive popularity of Twitter as a social media platform and its potential use in the areas of education and branding, the questions of why and how dental schools use these services warrant comprehensive research. Thus, the aim of this study was to analyze the pattern and use of Twitter as a social media platform for dental schools in Saudi Arabia.MethodsThe tweets were extracted within the timeframe from July 15, 2019, to July 15, 2020. The Twitter data collected included: full text content, the count of retweets, quotes, replies and likes. Extracted tweets were categorized into five main themes: news and announcement, dental professional communication, general communication, oral health education, and promoting participation. Tweets in each main theme were further categorized according to the dental schools' academic roles namely; education, research and community service. In addition, tweets were classified according to originality of the tweet, language used, nature of the tweet and the use of hashtags and mentions. Descriptive analysis presented in the form of frequency tables with percentages and mean (SD) as well as graphical presentation of the pattern and use of Twitter for Saudi dental schools in the form of bar, pie and line charts. Categorical data were analyzed using chi square test, while continuous data were analyzed using ANOVA. Statistical significance was set at p ≤ 0.05.ResultsA total of 15 Saudi dental schools with Twitter accounts were included in the analysis. King Saud University (KSU) had the largest number of followers with 17,200. Within the time frame of this study, a total of 1,889 original tweets from dental schools were found. Imam Abdulrahman Bin Faisal University (IAU) had the highest number of posted tweets (n = 647, 34.3%). The distribution of tweets was highest in September 2019 (n = 239) and lowest in July 2020 (n = 22). Majority of the tweets (81.9%) belonged to five out of the 15 dental schools. News and announcements were the most tweeted thematic subject with 1,034 tweets (55%). While community service was the most tweeted academic role with 803 tweets (42%). The top five active dental schools' performance for both thematic and academic role classifications were significantly different based on the chi square test (p < 0.001).ConclusionThis study highlights the importance of Twitter as a social media platform, in dental education especially when it comes to presence and branding for dental schools. Twitter is a helpful platform to expose dental schools to the community, this can be seen by their academic achievements as well as their active role with community service.
