A ten-year surveillance of P aeruginosa bloodstream infections in a tertiary care hospital: Trends and risk factors for mortality.

BACKGROUND: Pseudomonas aeruginosa (P aeruginosa) is a leading cause of nosocomial bloodstream infections worldwide. This study aimed to evaluate the incidence of P aeruginosa bloodstream infections and to identify predictors of 30-day mortality. METHODS: A retrospective study was conducted in an academic tertiary hospital in Jordan. The medical records of patients hospitalised over ten years (1 January 2008-31 December 2017) were reviewed to identify patients' positive blood culture of P aeruginosa. Annual incidence, antimicrobial susceptibility patterns and risk factors for 30-day mortality were analysed. RESULTS: A total of 169 cases of P aeruginosa bloodstream infection were identified, with an overall incidence rate of 0.23 case/1000 admission. The overall crude 30-day mortality was 36.7%. Receipt of corticosteroids (OR = 4.5; P = .0017), severe sepsis and septic shock (OR = 2.7; P = .0476), admission to intensive care unit (OR = 5.9; P = .0004), end-stage renal disease (OR = 4.1; P = .0123), inappropriate empirical therapy (OR = 3.2; P = .0143) and inappropriate definitive therapy (OR = 2.9; P = .0110) were identified as independent risk factors for mortality. CONCLUSION: The annual incidence of P aeruginosa BSIs was fluctuating over ten years period. Several predictors for 30-day mortality in patients with P aeruginosa BSIs were identified, including inappropriate empirical and definitive therapy.

Respiratory tract infection-induced asthma exacerbations in adults with asthma: assessing predictors and outcomes.

Objective: To evaluate clinical and economic burden associated with respiratory tract infection (RTI)-induced asthma exacerbations and to identify risk factors associated with these exacerbations. Factors associated with these exacerbations are understudied and little information is available about consequent expenditures. Methods: In this retrospective case-control study, medical records and pharmacy data in King Abdullah University Hospital in Northern Jordan were reviewed for adults with asthma aged 40 years and older, over the period 2013-2016. Cases of RTI-induced asthma exacerbations were identified, and controls were selected randomly from asthmatic adults who did not experience any RTI-induced asthma exacerbation during the same period. Independent-samples t-tests and chi-square tests were conducted to compare patient characteristics of cases and controls. Predictors of RTI-induced asthma exacerbations and the resultant complications were evaluated using multivariable logistic regression. Multivariable regression on log-transformed charges was used to predict expenditures of these exacerbations. Results: A total of 137 cases and 548 controls were identified. Using inhaled corticosteroid + long-acting beta-agonists (ICS + LABA) was significantly associated with lower odds of RTI-induced asthma exacerbations (OR = 0.4; 95% CI, 0.21-0.77; p = 0.006), and lower odds of resultant serious complications (OR = 0.23; 95% CI, 0.07-0.69; p = 0.009), compared to being untreated with any asthma maintenance treatment. Asthma severity and co-morbidities were associated with increased susceptibility to these exacerbations. The average charges of RTI-induced asthma admissions and outpatient exacerbations were 1042.9 JD ($1471.0) and 81.1 JD ($114.4), respectively. Conclusions: ICS + LABA, asthma severity and co-morbidities appeared to affect the clinical and economic burden associated with RTI-induced asthma exacerbations. Efforts to prevent these exacerbations in patients with risk factors are warranted.

Clinical patterns, epidemiology and risk factors of community-acquired urinary tract infection caused by extended-spectrum beta-lactamase producers: a prospective hospital case-control study.

PURPOSE: To assess incidence rate, risk factors and susceptibility patterns associated with extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli or Klebsiella pneumoniae in community-acquired urinary tract infections (CA-UTIs). METHODS: A prospective, case-control study was conducted at a tertiary teaching hospital from Jan 2015 to Dec 2016. The results of microbiology cultures were initially screened to include only patients with positive E. coli or K. pneumoniae urine cultures. Afterwards, clinical symptoms were assessed to confirm the UTI. To investigate the risk factors, patients with a positive urine culture for ESBL-producing isolates were assigned as cases, while patients with non-ESBL were assigned as controls. RESULTS: Out of 591 patients included in this study, 57.5% (n = 340) were included in the control group and 42.5% (n = 251) were in the case group. The incidence rate of ESBL-producing isolates was 3.465 cases per 1000-patient hospital admissions. Male gender (OR = 1.856, 95% CI = 1.192-2.889, p = 0.006), pediatrics (OR = 1.676, 95% CI = 1.117-2.517, p = 0.013), patients with comorbidity (OR = 1.542, 95% CI = 1.029-2.312, p = 0.036) and UTI in the previous 12 months (OR = 1.705, 95% CI = 1.106-2.628, p = 0.016) were independently associated with a higher risk of infection. The resistance rate for most commonly prescribed antibiotics was high. CONCLUSIONS: Our results suggest that the incidence of ESBL producers among CA-UTIs is high. Male gender, pediatrics, comorbidity and UTI in the previous 12 months were associated with a higher risk for infection. Continuous surveillance and prudent antibiotic use by healthcare professionals are important factors for effective control of ESBL associated infections.

A comparison of the left thoracoabdominal and Ivor-Lewis esophagectomy.

The purpose of this study was to assess the oncological outcomes of a large multicenter series of left thoracoabdominal esophagectomies, and compare these to the more widely utilized Ivor-Lewis esophagectomy. With ethics approval and an established study protocol, anonymized data from five centers were merged into a structured database. The study exposure was operative approach (ILE or LTE). The primary outcome measure was time to death. Secondary outcome measures included time to tumor recurrence, positive surgical resection margins, lymph node yield, postoperative death, and hospital length of stay. Cox proportional hazards models provided hazard ratios (HR) with 95% confidence intervals (CI) adjusting for age, pathological tumor stage, tumor grade, lymphovascular invasion, and neoadjuvant treatment. Among 1228 patients (598 ILE; 630 LTE), most (86%) had adenocarcinoma (AC) and were male (81%). Comparing ILE and LTE for AC patients, no difference was seen in terms of time to death (HR 0.904 95%CI 0.749-1.1090) or time to recurrence (HR 0.973 95%CI 0.768-1.232). The risk of a positive resection margin was also similar (OR 1.022 95%CI 0.731-1.429). Median lymph node yield did not differ between approaches (LTE 21; ILE 21; P = 0.426). In-hospital mortality was 2.4%, significantly lower in the LTE group (LTE 1.3%; ILE 3.6%; P = 0.004). Median hospital stay was 11 days in the LTE group and 14 days in the ILE group (P < 0.0001). In conclusion, this is the largest series of left thoracoabdominal esophagectomies to be submitted for publication and the only one to compare two different transthoracic esophagectomy strategies. It demonstrates oncological equivalence between operative approaches but possible short- term advantages to the left thoracoabdominal esophagectomy.

Evaluation of Behavioral and Susceptibility Patterns in Premenopausal Women with Recurrent Urinary Tract Infections: A Case Control Study.

Recurrent urinary tract infections (UTI) are a major source of morbidity and healthcare costs. Risk factors associated with recurrence rates in premenopausal women can be attributed to patient lifestyle behavior. The aim of this study was to assess hygienic risk factors, determine pathogen distribution, and susceptibility patterns in premenopausal women with recurrent UTI. This was case-control study in which a face-to-face interview was conducted to obtain information from premenopausal women with recurrent UTI. Microbiology cultures and susceptibility results were obtained to analyze pathogen distribution and resistance. In this study, 214 cases and 230 controls were compared and the following practices were associated with increased risk of recurrent UTI in multivariable analysis: washing genitals from back to front (OR 1.64 [95% CI 1.05-2.56]), not voiding within 15 min after intercourse (OR 2.81 [95% CI 1.72-4.66]), not drinking water after intercourse (OR 1.69 [95% CI 1.12-2.58]), using any soap to clean after urination (OR 2.11 [95% CI 1.42-3.17]). Escherichia coli were the most prevalent pathogens isolated (66.4%), followed by Klebsiella spp. (12.6%), Pseudomonas aeruginosa (12.1%), and Proteus spp., (6.6%). This study identified several modifiable sexual and hygienic practices associated with recurrent UTI in premenopausal women. Continuous surveillance of antimicrobial susceptibility patterns is important to overcome resistance.

Corticoids synergize with IL-1 in the induction of LCN2.

OBJECTIVE: Lipocalin-2 (LCN2) is an adipokine that was first identified in neutrophil granules. In the last years it was recognized as a factor that could impair chondrocyte phenotype, cartilage homeostasis as well as growth plate development. Both pro-inflammatory cytokines and glucocorticoids (GCs) modulate LCN2 expression. Actually, GCs were found to be LCN2 inducers, suggesting that part of the negative actions exerted by these anti-inflammatory drugs at cartilage level could be mediated by this adipokine. So, in this study we wanted to investigate whether corticoids were able to act in synergy with IL-1 in the induction of LCN2 and the signaling pathway involved in this process. MATERIALS AND METHODS: For the realization of this work, ATDC5 mouse chondrogenic cell line was used. We determined the mRNA and protein expression of LCN2 by real-time reverse transcription-polymerase chain reaction (RT-qPCR) and western blot respectively, after GC or mineralcorticoid treatment. Different signaling pathways inhibitors were also used. RESULTS: GC and mineralcorticoid were able to induce the expression of LCN2 in ATDC5 cells. Interestingly, both corticoids synergized with IL-1 in the induction of LCN2. The effect of these corticoids on the expression of LCN2 occurred through GC or mineralcorticoid receptors and the kinases PI3K, ERK1/2 and JAK2. CONCLUSIONS: Prolonged use of corticoids may have detrimental effects on cartilage homeostasis. Based on our results, we conclude that corticoids could increase the negative actions exerted by IL-1 by increasing the expression of LCN2.

Exposure to waterpipe smoke induces renal functional and oxidative biomarkers variations in mice.

CONTEXT: Waterpipe smoking (WPS) has been known for over 400 years. It has been spread widely especially between youth because of the addition of pleasant flavor and because it was misconsidered to be less harmful than cigarette. OBJECTIVE: In this study, we investigated the effect of waterpipe smoking on renal oxidative and functional parameters and compared that at acute and chronic exposure time in mice. MATERIALS AND METHODS: Mice were divided into three groups, namely acute, chronic and fresh air control. Acute group was exposed to waterpipe smoke for one hour daily for six days using whole-body exposure system, while chronic group was exposed to waterpipe smoke for one hour daily for 30 days using whole-body exposure system. RESULT: Exposure to waterpipe smoke has shown significant changes on the mice kidney functional parameters such as creatinine and blood urea nitrogen. Both exposures (acute and chronic) has shown a significant reduction in superoxide dismutase (SOD) activity (p < 0.05), whereas the activity of other antioxidant enzymes (catalase and GPx) reduced only with chronic exposure to waterpipe smoke (p < 0.05). Additionally, the level of thiobarbituric acid reactive substances (TBARS) in mice kidney homogenates has shown a significant elevation following chronic exposure to waterpipe smoke (p < 0.05). DISCUSSION AND CONCLUSION: In conclusion, chronic waterpipe smoke affects the kidney parameter and antioxidant markers, therefore affecting its functionality of detoxifying and removal of poisonous material from the body.

On the phase transitions of 8CB/Sn2P2S6 liquid crystal nanocolloids.

Using differential scanning calorimetry measurements, the influence of Sn2P2S6 ferroelectric nanoparticles on the phase transition temperatures of the 8CB liquid crystal is studied. The spontaneous polarization, ionic and anchoring effects are discussed. For low concentration of dopant, the global effect leads to a decrease and an increase of the nematic-isotropic and the smectic A-nematic phase transition temperatures, respectively. For high concentrations, due to aggregates formation, the predominant anchoring effect induces a decrease of the both phase transition temperatures.

Non-toxic plant metabolites regulate Staphylococcus viability and biofilm formation: a natural therapeutic strategy useful in the treatment and prevention of skin infections.

In the present study, the efficacy of generally recognised as safe (GRAS) antimicrobial plant metabolites in regulating the growth of Staphylococcus aureus and S. epidermidis was investigated. Thymol, carvacrol and eugenol showed the strongest antibacterial action against these microorganisms, at a subinhibitory concentration (SIC) of ≤ 50 µg ml(-1). Genistein, hydroquinone and resveratrol showed antimicrobial effects but with a wide concentration range (SIC = 50-1,000 µg ml(-1)), while catechin, gallic acid, protocatechuic acid, p-hydroxybenzoic acid and cranberry extract were the most biologically compatible molecules (SIC ≥ 1000 µg ml(-1)). Genistein, protocatechuic acid, cranberry extract, p-hydroxybenzoic acid and resveratrol also showed anti-biofilm activity against S. aureus, but not against S. epidermidis in which, surprisingly, these metabolites stimulated biofilm formation (between 35% and 1,200%). Binary combinations of cranberry extract and resveratrol with genistein, protocatechuic or p-hydroxibenzoic acid enhanced the stimulatory effect on S. epidermidis biofilm formation and maintained or even increased S. aureus anti-biofilm activity.

Evaluation of Antimicrobial Stewardship Programs and antibiotic prescribing patterns among physicians in ambulatory care settings in Jordan.

OBJECTIVES: Currently, there is an urgent need to implement an Antimicrobial Stewardship Program (ASP) in outpatient settings since nearly half of the antibiotic prescribing is inappropriate or unnecessary. The implementation of ASP should emphasize educational interventions that are more interactive. This study examines the adoption of outpatient ASP by physicians in Jordan. METHODS: A cross-sectional study was conducted between 2 March 2022 and 20 May 2022 at major hospitals in Jordan. The survey was distributed randomly among (n = 187) Jordanian physicians. RESULTS: It was found that more than half of the physicians were females (51.9%). The participants who reported not including antibiotic stewardship-related duties in position descriptions were (40.1%). While (46.5%) of participants reported writing and displaying public commitments supporting antibiotic stewardship in ambulatory care settings. Physicians' adoption of (action) core elements of ASPs in ambulatory care settings was positive. Almost (24.6%) reported a lack of self-evaluation of their antibiotic-prescribing practices. It was reported that (69.5%) of physicians used effective communication strategies to educate patients about when antibiotics are necessary. CONCLUSION: It was fair adoption of the core elements in the ambulatory care settings among Jordanian physicians. Progress necessitates a comprehensive strategy tailored to the needs of the health system.

Knowledge and attitudes towards herbal and dietary products use during the COVID-19 pandemic.

Background and aim: The outbreak of coronavirus (COVID-19) has made a global public health disaster. Little information is known about how to combat this infection. Therefore, preventive health measures that can reduce the severity and progression of this disease are needed. Some dietary supplements and herbal products have antiviral and anti-inflammatory effects. Thus, it may be used to enhance immunity and reduce the risk of COVID-19 infection. In this study, we reviewed selected supplements that may play a key role in the prevention and management of COVID-19 (e.g. vitamin D, vitamin C, and zinc), and that was to determine the level of knowledge and attitudes toward them by the adult population in Jordan. Methodology: This is a cross-sectional study design, in which an online questionnaire was conducted and distributed on different social media websites. People who are above 18 years old were included in this study. Demographic, Attitudes, and knowledge data were collected and then analyzed using the Statistical Package for Social Sciences (SPSS 23). Results: In this study, (62.8%) of participants became more concerned with their health during the COVID-19 pandemic, and (49.2%) of them used dietary and herbal supplements to protect themselves from the coronavirus. In addition, (18.5%) of participants reported that they had used these supplements for a while and then stopped. Conclusion: The findings of our study provided evidence that the general population in Jordan has a reasonable level of knowledge and acceptance of dietary and herbal supplements used during the COVID-19 pandemic.

The prevalence, risk factors and lifestyle patterns of Jordanian females with premenstrual syndrome: a cross-sectional study.

Aim: The study aims to assess factors associated with premenstrual syndrome (PMS) and the frequency of using painkillers to relieve premenstrual pain. Methods: This is a cross-sectional study of 1580 premenopausal women. An online self-administered questionnaire consists of sociodemographics, and the diagnostic criteria using the Arabic Premenstrual Syndrome Scale (A-PMS). Results: The prevalence of PMS among Jordanian females was 94%. Moreover, a significant correlation was found between several factors, including BMI, family history of PMS, smoking, and herbal tea consumption and the psychological, physical and behavioral symptoms of PMS. Furthermore, analgesic use for pain relief and food cravings were significantly associated with psychological, physical and behavioral PMS symptoms. Conclusion: PMS is highly prevalent and affects women in different life aspects.

Premenstrual syndrome (PMS) is a set of symptoms that affect women for a week or two before their period. PMS influences women's emotions, physical health and behavior. Symptoms usually resolve within a few days of menstruation. This study confirms the epidemiological surveys worldwide that reported 80­90% of females experience PMS symptoms. We reported multiple risk factors for PMS including age, weight, family history of PMS, marital status, smoking, herbal tea consumption, fast food consumption and other dietary habits. Furthermore, analgesic use for pain relief and food cravings were significantly associated with psychological, physical and behavioral PMS.

Clinical and economic outcomes associated with intravenous albumin fluid use in the intensive care unit: a retrospective cohort study.

OBJECTIVES: This study was undertaken to evaluate the prescribing practice of albumin in the intensive care unit (ICU) and to compare the clinical and economic outcomes associated with intravenous (IV) albumin compared to crystalloids in the ICU. METHODS: This was a retrospective cohort study of ICU adult patients admitted to King Abdullah University Hospital during 2018-2019. Patient demographics, clinical characteristics, and admission charges were retrieved from medical records and billing system. Survival analysis, multivariable regression models, and propensity score matching estimator were performed to evaluate the impact of IV resuscitation fluid types on the clinical and economic outcomes. RESULTS: Albumin administration in the ICU was associated with significantly lower hazards of ICU death (HR = 0.57; P value <0.001), but without improving overall death probability compared to crystalloids. Albumin was associated with significant prolongation in the ICU length of stay (5.86 days; P value <0.001). Only 88 patients (24.3%) were prescribed albumin for Food and Drug Administration (FDA)-approved indications. Admission charges were significantly higher for patients treated with albumin (p value <0.001). CONCLUSIONS: IV Albumin use in the ICU was not associated with significant improvement in clinical outcomes, but with a remarkable increase in economic burden. The majority of patients received albumin for non-FDA-approved indications.

Antimicrobial use and mortality among intensive care unit patients with bloodstream infections: implications for stewardship programs.

Background: Bloodstream infections (BSIs) are one of the most critical illnesses requiring intensive care unit (ICU) admission. Antimicrobial therapy (AMT) is one of the vital management strategies for the treatment of BSIs; it should be chosen appropriately to reduce mortality. Objectives: This is the first study to investigate the types of antimicrobial agents administered in the ICU setting and the predictor variables associated with mortality. Methods: This retrospective study was conducted at King Abdullah University Hospital (KAUH). All hospitalized patients admitted to the ICU and received at least one antimicrobial agent over 3 years period (January 1, 2017, to December 31, 2019) were included in the study. Electronic patients' medical records were used to collect patients' demographic and clinical characteristics, patient general health status, events that occurred during hospitalization, and events after obtaining the blood culture. Descriptive analysis was done to identify the types of antimicrobials used and the distribution of the microorganisms among the study participants. The susceptibility test of the bloodstream culture was checked for each patient. Moreover, crude mortality and its associated factors were investigated. Results: A total of 1051 patients were enrolled in the study, where 650 patients (61.84%) were treated with three or more antimicrobial agents. The most frequent antimicrobials used were piperacillin/tazobactam followed by teicoplanin, meropenem, and levofloxacin. About half of the patients died within 30-days of BSI, which was associated with several factors including advanced age, presence of co-morbidities, nosocomial infections or healthcare-associated infections, length of ICU stay, respiratory tract infections, receiving vasopressor during the hospital stay, concurrent positive culture other than blood with BSI, receiving combination antimicrobial therapy, those who were complicated with septic shock or renal failure, receiving total parenteral protein (TPN) nutrition, and inappropriate empiric antimicrobial therapy. Conclusion: In conclusion, the administration of the antimicrobials among ICU patients was highly based on a combination of three or more agents covering a broad spectrum of microorganisms. The mortality rate was high among patients which were associated with inappropriate empirical therapy. Therefore, the antimicrobial stewardship (ASP) protocol has to be evaluated in the hospital for ICU patients. Moreover, we suggest recommending that hospital policies should apply the ASP protocol, infection control, implement the antimicrobial de-escalation protocol, and do best controlling on the co-morbid conditions, especially for ages 65 years or more to reduce the mortality rate in the ICU.

Surveillance study of bloodstream infections, antimicrobial use, and resistance patterns among intensive care unit patients: A retrospective cross-sectional study.

Background: Bloodstream infections (BSIs) are one of the most critical illnesses requiring intensive care unit (ICU) admission. This study assessed patterns of antimicrobial use and resistance in ICU patients with BSIs. Methods: Inpatients admitted to the ICU and who received at least one antimicrobial agent between January 1, 2017, and December 31, 2019, were included in the study. Electronic patients' medical records were used to collect patients' demographic, clinical, and microbiological data. Results: A total of 1051 patients were enrolled in the study, where 650 patients (61.84%) were treated with three or more antimicrobial agents. The most frequently used antimicrobials were piperacillin/tazobactam followed by teicoplanin, meropenem, and levofloxacin. The most predominant multidrug-resistant pathogens were Acinetobacter baumannii, followed by Escherichia coli, Methicillin-resistant Staphylococcus aureus (MRSA), Klebsiella pneumonia, and Pseudomonas aeruginosa. Conclusions: The administration of the antimicrobials among ICU patients was highly based on a combination of three or more broad-spectrum agents. MDR pathogens were found to be highly prevalent among ICU patients with BSI. Therefore, we suggest recommending that hospital policies should apply the antimicrobial stewardship protocols, infection control, and implement antimicrobial de-escalation protocol to reduce the harm pressure of antimicrobial resistance.

Medication errors in Jordan: A systematic review.

Medication errors (MEs) present a significant issue in health care area, as they pose a threat to patient safety and could occur at any stage of the medication use process. The objective of this systematic review was to review studies reporting the rates, prevalence, and/or incidence of various MEs in different health care clinical settings in Jordan. We searched PubMed, HINARI, Google, and SCOPUS for relevant published studies. We included observational, cross-sectional or cohort studies on MEs targeting adults in different health-care settings in Jordan. A total of 411 records were identified through searching different databases. Following the removal of duplicates, screening of title, abstract and full-text screening, 24 papers were included for the final review step. Prescribing errors was the most common error reported in the included studies, where it was reported in 15 studies. The prevalence of prescribing errors ranged from 0.1% to 96%. Two studies reported unintentional discrepancies and documentation errors as other types of MEs, where the prevalence of unintentional discrepancies ranged from 47% to 67.9%, and the prevalence of documentation errors ranged from 33.7% to 65%. In conclusion, a wide variation was found between the reviewed studies in the error prevalence rates. This variation may be due to the variation in the clinical settings, targeted populations, methodologies employed. There is an imperative need for addressing the issue of MEs and improving drug therapy practice among health-care professionals by introducing education and training.

Cancer care for Ukrainian refugees: Strategic impact assessments in the early days of the conflict.

BACKGROUND: The invasion of Ukraine by Russia in February 2022 has resulted in destruction of healthcare infrastructure and triggered the largest wave of internally displaced populations and refugees since World War Two. Conflicts in transitioned countries such as Ukraine create new non-communicable disease (NCD) challenges, especially for cancer care for refugees and humanitarian assistance in host countries. In the early days, rapid attempts were made to model possible impacts. METHODS: By evaluating open source intelligence used in the first three months of the conflict through snowball search methods, we aimed to address: (i) burden of cancer in Ukrainian population, specifically considering translating to the refugees population, and its cancer care capacity; ii) baseline capacity/strengths of cancer systems in initial host countries. Moreover, using a baseline scenario based on crude cancer incidence in Ukraine, and considering data from UNHCR, we estimated how cancer cases would be distributed across host countries. Finally, a surveillance assessment instrument was created, intersecting health system's capacity and influx of internally displaced populations and refugees. FINDINGS AND CONCLUSIONS: The total new cancer patients per month in pre-conflict Ukraine was estimated as 13,106, of which < 1 % are paediatric cases. The estimated cancer cases in the refugee population (combining prevalent and incident), assuming 7.5 million refugees by July 2022 and a female:male ratio of 9:1, was 33,121 individuals (Poland: 19284; Hungary: 3484; Moldova: 2651; Slovakia: 2421; Romania: 5281). According to our assessments, Poland is the only neighbouring country classified as green/yellow for cancer capacity, i.e. sufficient ablility to absorb additional burden into national health system; Slovakia we graded as yellow, Hungary and Romania as yellow/red and Moldova as red.

A systematic review of Antimicrobial Stewardship Program implementation in Middle Eastern countries.

BACKGROUND: Antimicrobial resistance is a serious threat to global health. Antimicrobial Stewardship Programs (ASPs) are adopted by healthcare systems worldwide. This review aimed to evaluate the published practices of ASPs in Middle Eastern countries. METHODS: Searches were carried out in PubMed/MEDLINE, Embase, EBSCO, Cochrane Library, Google, and Google Scholar electronic databases for studies published from January 2005 to December 2020 that assessed ASP practices in Middle Eastern countries, following PRISMA guidelines. RESULTS: Of the 422 titles identified, 20 studies met the inclusion criteria. Eight studies were conducted in the Kingdom of Saudi Arabia, five in Qatar, two each in Lebanon and Jordan, and one each in Palestine and UAE; there was also one multinational study. Different ASP practices, including prospective auditing and feedback, pre-authorization, tracking, antibiotic restriction, education, de-escalation, and intravenous-to-oral switch, were reported. ASP practices correlated with improved susceptibility rates and decreases in antimicrobial use. CONCLUSION: The outcomes of this review reveal the scarcity of data on ASP practices. The introduction of ASPs in hospitals in Middle Eastern countries has led to favorable clinical effects. Policymakers and stakeholders should promote and invest in implementing these programs as an essential component of their healthcare systems.

Prevalence of antimicrobial use in a tertiary academic hospital: a venue for antimicrobial stewardship programs.

OBJECTIVE: To quantify antimicrobial use in inpatients setting as part of antimicrobial stewardship program surveillance. METHOD: Antimicrobial use was obtained using a pre-designed data collection form in this point prevalence study. Setting: The study was conducted in a tertiary academic hospital in the North of Jordan on 13 August 2018. Main outcome measures: antimicrobial use was determined using two methods: defined daily use (DDD) and days of therapy (DOT). RESULTS: This study identified antimicrobial use in 144 patients. Carbapenems, glycopeptides, and piperacillin-tazobactam were the most utilized antimicrobials in the inpatients' setting in both measures DDD and DOT. The highest prescription rate of antibiotics was in the internal medicine wards (49.8 DDD/100 admissions), followed by surgery wards (33.2 DDD/100 admissions) and intensive care unit (20.6 DDD/100 admissions). CONCLUSION: This surveillance study addressed patterns of antimicrobial usage in inpatients settings in a tertiary care hospital in Jordan. This practice is feasible and could be adopted routinely by antimicrobial stewardship programs.

Waterpipe tobacco smoke and health: What we have learned from rodent models?

AIMS: Waterpipe smoking (WPS) is a popular form of tobacco smoking. This is due to the misperception that WPS is less detrimental than cigarette smoking. This review aimed to present the adverse effects of WPS on health outcomes through utilizing animal models. MAIN METHODS: The design of the current study is systematic review. PubMed, HINARI, Google, and SCOPUS databases were searched for the adverse effects of WPS on general health in rodents. Certain key information was extracted and collected from the included studies. KEY FINDINGS: After screening different databases and removal of duplicates, 43 papers were included in this review. It was found that WPS was able to negatively affect the oxidative stress and inflammatory biomarkers in mice. Furthermore, WPS increased the levels of Tumor necrosis factor-α and 8-isoprostane, and DNA damage in mice lung homogenates. Additionally, chronic exposure to WPS increased the serum levels of creatinine and blood urea nitrogen in mice; indicating injury to renal tissues. The negative effect of WPS extends to affect offspring rats following prenatal WPS, in which WPS in utero lead to remarkable increase in the levels of testosterone, estrogen and follicle-stimulating hormones in WPS exposed animals. SIGNIFICANCE: This systematic review highlighted the adverse effects of WPS on health outcomes at cellular and biochemical levels in different tissues and organs of rodents. The current reviews' findings highlighted the great hazards presented by WPS in the selected rodents' model and the essential necessity for future improved management of WPS indoor consumption.
