Abstract
Background Antimicrobial consumption continues to rise globally and contributes to the emergence and spread of antimicrobial resistance. This study aimed to evaluate antimicrobial prescribing patterns in a selected tertiary hospital in Tanzania. Methods This cross-sectional study was conducted for one year (September 2021-September 2022) at Mbeya Zonal Referral Hospital, a public hospital in the southern highlands zone of Tanzania. Data on clinical diagnosis, laboratory tests, prescribed antimicrobials, and prescribers' designations were collected through a custom eMedical system, aligning antimicrobials with the WHO's 2021 AWaRe classification. Descriptive analysis was performed to assess the pattern of antimicrobial prescriptions. Results Of 2,293 antimicrobial prescriptions, 62.41% were ACCESS, 37.42% were WATCH, and 0.17% fell in the RESERVE categories. Metronidazole, accounting for 23.8%, was the most commonly prescribed antimicrobial. More than 50% of the ACCESS and WATCH prescriptions were justified by laboratory diagnosis and were predominantly prescribed by clinicians. A very small proportion of prescriptions (<1%) were informed by culture and sensitivity (C/S) testing. The Paediatric department had the majority of WATCH prescriptions (72.2%). Conclusion The prescribing patterns at the study hospital generally align with WHO AWaRe guidelines, potentially mitigating antimicrobial resistance. Nevertheless, the scarcity of culture and sensitivity testing is a concern that warrants targeted improvement.

Opinion review of drug resistant tuberculosis in West Africa: tackling the challenges for effective control. Front Public Health 2024; 12:1374703. [PMID: 38827613 PMCID: PMC11141065 DOI: 10.3389/fpubh.2024.1374703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Accepted: 04/29/2024] [Indexed: 06/04/2024] Open
Abstract
Drug-resistant (DR) tuberculosis (TB) is a major public health concern globally, complicating TB control and management efforts. West Africa has historically faced difficulty in combating DR-TB due to limited diagnostic skills, insufficient access to excellent healthcare, and ineffective healthcare systems. This has aided in the emergence and dissemination of DR Mycobacterium tuberculosis complex (MTBC) strains in the region. In the past, DR-TB patients faced insufficient resources, fragmented efforts, and suboptimal treatment outcomes. However, current efforts to combat DR-TB in the region are promising. These efforts include strengthening diagnostic capacities, improving access to quality healthcare services, and implementing evidence-based treatment regimens for DR-TB. Additionally, many West African National TB control programs are collaborating with international partners to scale up laboratory infrastructure, enhance surveillance systems, and promote infection control measures. Moreso, novel TB drugs and regimens, such as bedaquiline and delamanid, are being introduced to improve treatment outcomes for DR-TB cases. Despite these obstacles, there is optimism for the future of DR-TB control in West Africa. Investments are being made to improve healthcare systems, expand laboratory capacity, and support TB research and innovation. West African institutions are now supporting knowledge sharing, capacity building, and resource mobilization through collaborative initiatives such as the West African Network for TB, AIDS, and Malaria (WANETAM), the West African Health Organization (WAHO), and other regional or global partners. These efforts hold promise for improved diagnostics, optimized treatment regimens, and provide better patient outcomes in the future where drug-resistant TB in WA can be effectively controlled, reducing the burden of the disease, and improving the health outcomes of affected individuals.

Assessment of Physicians' Practice in Implementing Antibiotic Stewardship Program in Najran City, Saudi Arabia: A Cross-Sectional Study. PHARMACY 2024; 12:24. [PMID: 38392931 PMCID: PMC10892749 DOI: 10.3390/pharmacy12010024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 01/20/2024] [Accepted: 01/23/2024] [Indexed: 02/25/2024] Open
Abstract
INTRODUCTION One of the main causes of illness, mortality, and rising medical costs is antimicrobial resistance, which is a global healthcare concern. OBJECTIVES This study explores the practice of physicians toward the effective implementation of Antibiotic Stewardship Programs (ASPs) in Najran city, Saudi Arabia. METHODOLOGY This cross-sectional study was conducted among physicians working at primary care setting in Najran city, Saudi Arabia, between May and August 2023. A self-administered questionnaire was distributed among the physicians composed of three parts: socio-demographic data, a questionnaire about physicians' practice in the efficacy of ASP, and a questionnaire about physicians' practice regarding prescribing antibiotics. RESULTS Of the 128 physicians who participated in the study, 60.2% were males, and 43.8% were aged between 36 and 45 years. Among the practices in implementing the ASP effectively, controlling the source of infection domain received the highest score (mean score: 4.83). Every practice domain mean score was greater than 3, indicating that study participants possessed a moderate level of ASP practice and implementation skills. The overall mean practice score in the effective implementation of ASP was 154.9 ± 25.5 out of 185 points, with good, moderate, and poor practices constituting 67.2%, 28.1%, and 4.7%, respectively. CONCLUSIONS The physicians showed a moderate level of practice for the effective implementation of ASPs in Najran city. The factors significantly associated with increased practice score include older age, male gender, Saudi nationality, handling five or fewer infection cases daily, and infection-initiated antibiotic prescribing treatment managed per day. These findings suggest the need for targeted interventions and educational programs to enhance physicians' adherence to ASP guidelines and promote appropriate antibiotic prescribing practices, ultimately contributing to global efforts in combating antimicrobial resistance and improving patient outcomes.

Abstract
OBJECTIVES This study aimed to evaluate the common clinical diagnoses and treatment management of acute respiratory infections (ARIs) in children and determine when antibiotics are recommended and prescribed. METHODS A retrospective review of medical charts was carried out at King Salman Bin Abdulaziz Medical City (KSAMC) Hospital to assess pediatric patients diagnosed with ARIs aged 0-14 years, excluding those requiring antibiotics for conditions other than ARIs. Data, including demographic diagnoses and treatment management, were extracted using consecutive sampling, and statistical analyses were conducted using Jamovi software. RESULTS A total of 285 pediatric patients were included, with a median age of 3 (IQR = 1-6) years and a male predominance of 59.2%. Bronchopneumonia was the most common respiratory disease, diagnosed in 39.1% of participants. The median durations for illness and hospital admission were four and three days, respectively. Clinical evaluations showed an average respiratory rate of 28±10.5 breaths per minute and a mean oxygen saturation of 96.4±3.46% through pulse oximetry. The use of antibiotics was commonly prescribed in ARI patients only when accompanied by certain bacterial infections (46.32%). CONCLUSIONS ARIs are a common viral health issue among children, emphasizing that not all ARIs in children are caused by bacteria and that antibiotics should only be used when there is a bacterial infection present. Enhanced diagnostic precision, patient awareness, and provider education are the global community's recommendations to prevent the presence of antibiotic resistance and the irrational use of antibiotics.

Abstract
Antimicrobial resistance has become a serious global issue, posing a significant threat to public health and healthcare professionals. Since the advent of penicillin, many antibiotics have lost their effectiveness in combating microbes simply due to inappropriate, irrational, unnecessary, and unrestricted use. The ineffectiveness of an increasing number of antibiotics necessitates the utilization of more potent antimicrobial agents for combatting uncomplicated infections. In response to the escalating prevalence of multidrug-resistant pathogens and the imperative to curtail the demand for novel antibiotics, the Antimicrobial Stewardship Program was conceived and implemented. This initiative is characterized by a lead physician, ideally possessing expertise in infectious diseases, alongside a pharmacist serving as a secondary leader and a microbiologist with defined responsibilities to achieve several objectives. These objectives include reducing indiscriminate usage of antimicrobial agents, promoting selective antimicrobial utilization based on culture results, de-escalating therapy from broad-spectrum to targeted antimicrobial agents, and transitioning from parenteral to oral administration when feasible. These objectives are pursued through a combination of pre-prescription and post-prescription strategies. While the Antimicrobial Stewardship Program is widely established in developed nations, a pressing need exists for its more comprehensive implementation in less developed regions. This review aims to examine the strategies used in antimicrobial stewardship programs to evaluate their effectiveness in preventing the development of multidrug-resistant organisms (MDROs) based on existing research studies. Under the Antimicrobial Stewardship Program, education of healthcare professionals and continuous disposal of information about antimicrobial resistance have helped to restrict the emergence of multidrug-resistant organisms.

Abstract
BACKGROUND Antibiotic resistance is a worldwide health concern that necessitates antibiotic stewardship. Medical students significantly impact future healthcare practices; thus, their trust in antibiotic prescription and administration is crucial. This research aims to assess medical students' levels of confidence and knowledge in these areas before and after exposure to virtual antibiotic stewardship education. METHODS A one-group pretest-posttest design was conducted with medical students from King Saud bin Abdulaziz University for Health Sciences in Jeddah, Saudi Arabia. Participants were enrolled in the WHO-online antibiotic stewardship course. RESULTS The group's baseline confidence and background knowledge were reported to be lower than what was offered after introducing the virtual course. The McNemar-Bowker test showed a significant difference in students' confidence in pre-course and post-course scores (Z = 20, p < 0.002); the matched paired t-test revealed a significant difference in students' knowledge scores (M = 7.66 verses M = 5.36, Z = 3.54, p = 0.001). In the sample, 70% of the students were unfamiliar with antibiotic stewardship; thus, the analysis revealed a significant difference in their familiarity before and after enrolling in the online course (30 vs. 100, p < 0.001). CONCLUSION Medical students experience low confidence in the safe practice of the antibiotic stewardship program. The WHO-online antibiotic stewardship course is considered a valuable resource that can be used in a formative medical curriculum. Thus, educators and the academic curriculum must promote practical strategies to minimize antibiotic stewardship literacy and increase antibiotic prescribing and administration quality. Introducing antibiotic stewardship across the medical curriculum and establishing educational courses are some strategies that can be undertaken to ensure that future doctors are well-educated in the principles and practices of the appropriate use of antibiotic stewardship.

Abstract
The rise of antimicrobial resistance (AMR) is a major global public health threat due to excessive and inappropriate use of antibiotics and is responsible for prolonged illness, longer hospital stays, and economic burden to society. This article aims to review the factors, role of antimicrobial stewardship, preventive strategies, and role of various organizations in combating AMR. Three major factors of AMR are inappropriate and excessive utilization of antibiotics, nonadherence to infection control measures, and the emergence of pathogens that are resistant to multiple drugs. Antimicrobial stewardship initiatives play a vital role in promoting judicious and targeted utilization of antimicrobials, thereby safeguarding their efficacy and mitigating the emergence of resistance. Implementing such programs optimizes patient outcomes by ensuring that individuals receive the most suitable therapeutic interventions. International organizations have a vital role to play in addressing AMR by promoting the responsible use of antimicrobials, developing new drugs, and improving surveillance systems. As AMR's impact grows, it is critical to take a collaborative and interdisciplinary approach to mitigate its consequences effectively.

Surgical Antibiotic Prophylaxis Administration Improved after introducing Dedicated Guidelines: A Before-and-After Study from Dhulikhel Hospital in Nepal (2019-2023). Trop Med Infect Dis 2023; 8:420. [PMID: 37624358 PMCID: PMC10615196 DOI: 10.3390/tropicalmed8080420] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 08/07/2023] [Accepted: 08/14/2023] [Indexed: 08/26/2023] Open
Abstract
(1) Background: Surgical antibiotic prophylaxis (SAP) is important for reducing surgical site infections. The development of a dedicated hospital SAP guideline in the Dhulikhel Hospital was a recommendation from a baseline study on SAP compliance. Compliance with this new guideline was enhanced through the establishment of a hospital committee, the establishment of an antibiotic stewardship program and the funding and training of healthcare professionals. Using the baseline and a follow-up study after introducing dedicated hospital SAP guidelines, we compared: (a) overall compliance with the SAP guidelines and (b) the proportion of eligible and non-eligible patients who received initial and redosing of SAP; (2) Methods: A before-and-after cohort study was conducted to compare SAP compliance between a baseline study (July 2019-December 2019) and a follow-up study (January 2023-April 2023); (3) Results: A total of 874 patients were in the baseline study and 751 in the follow-up study. Overall SAP compliance increased from 75% (baseline) to 85% in the follow-up study (p < 0.001). Over 90% of those eligible for the initial dose of SAP received it in both studies. Inappropriate use for those not eligible for an initial dose was reduced from 50% to 38% (p = 0.04). For those eligible for redosing, this increased from 14% to 22% but was not statistically significant (p = 0.272); (4) Conclusions: Although there is room for improvement, introduction of dedicated SAP guidelines was associated with improved overall SAP compliance. This study highlights the role of operational research in triggering favorable interventions in hospital clinical care.

[PMID: 37508288 PMCID: PMC10376400 DOI: 10.3390/antibiotics12071192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 07/08/2023] [Accepted: 07/13/2023] [Indexed: 07/30/2023] Open
Abstract
(1) Background: Piperacillin/tazobactam is a broad-spectrum antimicrobial encompassing most Gram-positive and Gram-negative aerobic and anaerobic bacteria. The inappropriate use of such broad-spectrum antibiotics is an important contributor to the rising rates of antimicrobial drug resistance worldwide. Drug utilization evaluation studies and pharmacists' interventions are vital to assess, develop, and promote the rational use of antibiotics. This drug utilization study aimed to evaluate the current utilization practice of piperacillin/tazobactam in a hospital setting and assess the impact of pharmacist intervention in improving its appropriate use. (2) Methodology: In this study, we used a retrospective cohort and a prospective cohort, a cross-sectional, observational method. It included a retrospective (Cycle A/pre-intervention-CycA) phase followed by an educational interventional phase conducted by the pharmacists. During the 2 months of educational intervention, pharmacists used several methods, including workshops, lectures, oral presentations, and the development and reinforcement of clinical pathways to promote the judicious use of piperacillin/tazobactam. This was followed by a prospective (Cycle B/post-intervention-CycB) phase to improve piperacillin/tazobactam usage appropriateness. The appropriateness criteria for this drug utilization evaluation were established based on antimicrobial guidelines, the published literature, the institutional antibiogram, consultation from the antimicrobial stewardship committee, and the product monograph (Tazocin). The appropriateness of CycA and CycB patients was compared using the measurable elements, including indication and dose based on renal function, timely order for cultures, de-escalation, and use of extended infusion protocol. (3) Results: The study population comprised 100 patients in both CycA and CycB. The mean age of the patients was 66.28 ± 16.15 and 67.35 ± 17.98, and the ratios of men to women were found to be 49:51 and 61:39 in CycA and CycB, respectively. It was observed that inappropriate usage was high in CycA patients, and the appropriateness was improved in CycB patients. A total of 31% of inappropriate empirical broad-spectrum use was found in CycA, and it was reduced to 12% in CycB patients. The transition of appropriateness was observed in all measurable criteria, which includes the optimized dose according to the renal function (CycA = 49% to CycB = 94%), timely bacterial culture orders (CycA = 47% to CycB = 74%), prompt de-escalation (CycA = 31% to CycB = 53%), and adherence to extended infusion institutional guidelines (CycA = 34% to CycB = 86%). (4) Conclusions: The study highlighted important aspects of inappropriate piperacillin/tazobactam use. This can be considerably improved by proper education and timely interventions based on the pharmacists' vigilant approach. The study results emphasized the need for surveillance of piperacillin/tazobactam usage by conducting similar drug utilization evaluations and practice to improve quality and safety in healthcare organizations globally.

Abstract
The emergence of multidrug-resistant Acinetobacter baumannii is a major concern to healthcare providers and facilities in many parts of the world. This bacterial pathogen is commonly implicated in hospital-acquired infections, particularly in critically ill patients admitted to the intensive care unit (ICU). The extensive use of antibiotics, particularly in ICUs, and the lack of proper infection control interventions in many hospitals have led to an increased emergence of multidrug-resistant A. baumannii. Infections due to multidrug-resistant A. baumannii are associated with prolonged hospital stays and high morbidity and mortality, particularly among hospitalized ICU patients. The lack of antibiotic stewardship programmes in many healthcare facilities has exacerbated the burden of A. baumannii infections in many parts of Africa. This review discusses the prevalence and antibiotic-resistance pattern of the multidrug-resistant A. baumannii, and the possible ways to address or minimise its emergence in healthcare settings in Africa.

Abstract
The importance of antibiotic stewardship is increasingly emphasized in accordance with the increasing incidences of multidrug-resistant organisms and accompanying increases in disease burden. This review describes the obstacles in operating an antibiotic stewardship program (ASP), and whether the use of biomarkers within currently available resources can help. Surveys conducted around the world have shown that major obstacles to ASPs are shortages of time and personnel, lack of appropriate compensation for ASP operation, and lack of guidelines or appropriate manuals. Sufficient investment, such as the provision of full-time equivalent ASP practitioners, and adoption of computerized clinical decision systems are useful measures to improve ASP within an institution. However, these methods are not easy in terms of both time commitments and cost. Some biomarkers, such as C-reactive protein, procalcitonin, and presepsin are promising tools in ASP due to their utility in diagnosis and forecasting the prognosis of sepsis. Recent studies have demonstrated the usefulness of algorithmic approaches based on procalcitonin level to determine the initiation or discontinuation of antibiotics, which would be helpful in decreasing antibiotics use, resulting in more appropriate antibiotics use.

Endolysins of bacteriophage vB_Sal-S-S10 can naturally lyse Salmonella enteritidis. BMC Vet Res 2022; 18:410. [PMID: 36411417 PMCID: PMC9677904 DOI: 10.1186/s12917-022-03514-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Accepted: 11/10/2022] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND The holin-endolysin lysis system plays an essential role in the phage life cycle. Endolysins are promising alternatives to antibiotics, and have been successfully used against Gram-positive bacteria. However, a few endolysins can externally lyse Gram-negative bacteria, due to the inaccessible peptidoglycan layer covered by the envelope. RESULTS This study investigated the lysis system of a new Siphoviridae bacteriophage vB_Sal-S-S10 (S10), which, that was isolated from broiler farms, was found to be able to infect 51.4% (37/72) of tested S. enteritidis strains. Phage S10 genome had a classic holin-endolysin lysis system, except that one holin and one endolysin gene were functionally annotated. The orf 22 adjacent to the lysis cassette was identified as a new endolysin gene. Antibacterial activity assays showed that holin had an intracellular penetrating activity against S. enteritidis 35; both endolysins acted on the cell envelope of S. enteritidis 35 and showed a natural extracellular antibacterial activity, leading to a ~ 1 log titer decrease in 30 min. Protein characterization of lysin1 and lysin2 revealed that the majority of the N-terminus and the C-terminus were hydrophobic amino acids or positively charged. CONCLUSION In this study, a new Salmonella phage vB_Sal-S-S10 (S10) was characterized and showed an ideal development prospect. Phage S10 has a classic holin-endolysin lysis system, carrying an overlapping holin-lysin gene and a novel lysin gene. Both endolysins coded by lysin genes could externally lyse S. enteritidis. The natural extracellular antibacterial character of endolysins would provide necessary information for the development of engineering endolysin as the antibiotic alternative against the infection with multidrug-resistant gram-negative bacteria.

Abstract
Staphylococcusaureus is an important opportunistic pathogen that causes many infections in humans and animals. The inappropriate use of antibiotics has favored the diffusion of methicillin-resistant S. aureus (MRSA), nullifying the efforts undertaken in the discovery of antimicrobial agents. Oxadiazole heterocycles represent privileged scaffolds for the development of new drugs because of their unique bioisosteric properties, easy synthesis, and therapeutic potential. A vast number of oxadiazole-containing derivatives have been discovered as potent antibacterial agents against multidrug-resistant MRSA strains. Here, we investigate the ability of a new library of oxadiazoles to contrast the growth of Gram-positive and Gram-negative strains. The strongest antimicrobial activity was obtained with compounds 3 (4 µM) and 12 (2 µM). Compound 12, selected for further evaluation, was found to be noncytotoxic on the HaCaT cell line up to 25 µM, bactericidal, and was able to improve the activity of oxacillin against the MRSA. The highest synergistic interaction was obtained with the combination values of 0.78 μM for compound 12, and 0.06 μg/mL for oxacillin. The FIC index value of 0.396 confirms the synergistic effect of compound 12 and oxacillin. MRSA treatment with compound 12 reduced the expression of genes included in the mec operon. In conclusion, 12 inhibited the growth of the MRSA and restored the activity of oxacillin, thus resulting in a promising compound in the treatment of MRSA infection.

Problems associated with the use of the term "antibiotics". Naunyn Schmiedebergs Arch Pharmacol 2021; 394:2153-2166.

Abstract
The term “antibiotics” is a broadly used misnomer to designate antibacterial drugs. In a recent article, we have proposed to replace, e.g., the term “antibiotics” by “antibacterial drugs”, “antibiosis” by “antibacterial therapy”, “antibiogram” by “antibacteriogram”, and “antibiotic stewardship” by “antibacterial stewardship” (Seifert and Schirmer Trends Microbiol, 2021). In the present article, we show that many traditional terms related to antibiotics are used much more widely in the biomedical literature than the respective scientifically precise terms. This practice should be stopped. Moreover, we provide arguments to end the use of other broadly used terms in the biomedical literature such as “narrow-spectrum antibiotics” and “reserve antibiotics”, “chemotherapeutics”, and “tuberculostatics”. Finally, we provide several examples showing that antibacterial drugs are used for non-antibacterial indications and that some non-antibacterial drugs are used for antibacterial indications now. Thus, the increasing importance of drug repurposing renders it important to drop short designations of drug classes such as “antibiotics”. Rather, the term “drug” should be explicitly used, facilitating the inclusion of newly emerging indications such as antipsychotic and anti-inflammatory. This article is part of an effort to implement a new rational nomenclature of drug classes across the entire field of pharmacology.

Abstract
BACKGROUND Antibiotic stewardship programs have been a major focus in recent years to curtail antibiotic resistance. The purpose of this study was to evaluate antibiotic utilization for acute respiratory tract infections (ARTI) in the Emergency Department (ED) setting. MATERIAL AND METHODS A retrospective analysis of adult ARTI visits to EDs utilizing 2011-2017 National Hospital Ambulatory Medical Care Survey- Emergency Department (NHAMCS-ED) datasets was conducted. Included were all visits of adults (≥18 years) diagnosed with ARTI. Antibiotics were determined based upon NHAMCS-ED use of the Multum Lexicon Drug Database coding system. All significance tests were two-sided, P-value <0.05 for significance. RESULTS A total of 4632 unweighted ED visits, which represented more than 28 million US ED visits from 2011 to 2017, with 57.2% receiving a prescription for antibiotics. Antibiotic prescriptions for ARTI significantly declined from 65.8% in 2011 to 54.3% in 2017 (P = 0.046). Among all visits, patients were more likely to receive an antibiotic if they were over age 45 (33.0% vs 27.6%, P = 0.005), male (36.7% vs. 32.3%, P = 0.039), and presenting in a non-MSA ED (21.4% vs. 14.5%, P = 0.002). No association was found between antibiotic prescription and race (P = 0.076) insurance (P = 0.488), CBC (P = 0.148), x-ray (P = 0.278), and blood cultures (P = 0.182). CONCLUSION We found a significant reduction in the utilization of antibiotics among adult ARTI visits to U.S. EDs from 2011 to 2017. This is an improvement from previous studies which showed no change, suggesting that antimicrobial stewardship efforts may be impacting overall antibiotic use and should continue to be practiced.

Abstract
Classical resistance classifications (multidrug resistance [MDR], extensive drug resistance [XDR], pan-drug resistance [PDR]) are very useful for epidemiological purposes, however, they may not correlate well with clinical outcomes, therefore, several novel classification criteria (e.g., usual drug resistance [UDR], difficult-to-treat resistance [DTR]) were introduced for Gram-negative bacteria in recent years. Microbiological and resistance data was collected for urinary tract infections (UTIs) retrospectively, corresponding to the 2008.01.01–2017.12.31. period. Isolates were classified into various resistance categories (wild type/susceptible, UDR, MDR, XDR, DTR and PDR), in addition, two new indicators (modified DTR; mDTR and mcDTR) and a predictive composite score (pMAR) were introduced. Results: n = 16,240 (76.8%) outpatient and n = 13,386 (69.3%) inpatient UTI isolates were relevant to our analysis. Citrobacter-Enterobacter-Serratia had the highest level of UDR isolates (88.9%), the Proteus-Providencia-Morganella group had the highest mDTR levels. MDR levels were highest in Acinetobacter spp. (9.7%) and Proteus-Providencia-Morganella (9.1%). XDR- and DTR-levels were higher in non-fermenters (XDR: 1.7%–4.7%. DTR: 7.3%–7.9%) than in Enterobacterales isolates (XDR: 0%–0.1%. DTR: 0.02%–1.5%). Conclusions: The introduction of DTR (and its’ modifications detailed in this study) to the bedside and in clinical practice will definitely lead to substantial benefits in the assessment of the significance of bacterial resistance in human therapeutics.

Abstract
Background and Aim The misuse and abuse of antibiotics by human and in animal production are leading to serious threats to global health. This study aimed to assess the dietary exposure of Lebanese consumers to antibiotic residues from the consumption of meat and compare it to that from medication intake. Materials and Methods Beef samples (n=61) were collected and analyzed for penicillin residues using enzyme-linked immunosorbent assay and high-performance liquid chromatography. A cross-sectional study recruited 500 participants living in Mount Lebanon, using an interviewer-based questionnaire. The dietary exposure assessment was calculated following the tiered assessment approach. Results The results showed that only 44% of the participants reported using antibiotic on doctor's prescription. Participants with good antibiotic knowledge (6-7/7) are significantly less likely to change antibiotic during treatment and would better use them as compared to those with lower knowledge (p=0.000). Those with lower education and monthly household income are more likely to improperly use antibiotics as compared to those with higher education and income. Penicillin -containing antibiotics were among the most used medications. On the other hand, the prevalence of penicillin residues in the meat samples was 21.3%, though none was above the maximum residue level. The dietary exposure to penicillin through meat consumption was equivalent to 88.3%, 31.9%, and 5.7% of the acceptable daily intake, using Tier 1, 2, and 3 approaches, respectively. Males, single, obese participants, and those with household income below 999,000 Lebanese pound were significantly more exposed to penicillin as compared to other participants due to their high meat consumption. Conclusion These findings will provide insight into designing future targeted awareness interventions and adapted policies as efforts toward improving rational use and intake of antibiotics for preventing the development of antibiotic resistance.

Abstract
Staphylococcus aureus has been an exceptionally successful pathogen, which is still relevant in modern age-medicine due to its adaptability and tenacity. This bacterium may be a causative agent in a plethora of infections, owing to its abundance (in the environment and in the normal flora) and the variety of virulence factors that it possesses. Methicillin-resistant S. aureus (MRSA) strains—first described in 1961—are characterized by an altered penicillin-binding protein (PBP2a/c) and resistance to all penicillins, cephalosporins, and carbapenems, which makes the β-lactam armamentarium clinically ineffective. The acquisition of additional resistance determinants further complicates their eradication; therefore, MRSA can be considered as the first representative of multidrug-resistant bacteria. Based on 230 references, the aim of this review is to recap the history, the emergence, and clinical features of various MRSA infections (hospital-, community-, and livestock-associated), and to summarize the current advances regarding MRSA screening, typing, and therapeutic options (including lipoglycopeptides, oxazolidinones, anti-MRSA cephalosporins, novel pleuromutilin-, tetracycline- and quinolone-derivatives, daptomycin, fusidic acid, in addition to drug candidates in the development phase), both for an audience of clinical microbiologists and infectious disease specialists.

Abstract
The emergence and spread of antibiotic-resistant pathogens is a major public health issue, which requires global action of an intersectoral nature. Multidrug-resistant (MDR) pathogens-especially "ESKAPE" bacteria-can withstand lethal doses of antibiotics with various chemical structures and mechanisms of action. Pharmaceutical companies are increasingly turning away from participating in the development of new antibiotics, due to the regulatory environment and the financial risks. There is an urgent need for innovation in antibiotic research, as classical discovery platforms (e.g., mining soil Streptomycetes) are no longer viable options. In addition to discovery platforms, a concept of an ideal antibiotic should be postulated, to act as a blueprint for future drugs, and to aid researchers, pharmaceutical companies, and relevant stakeholders in selecting lead compounds. Based on 150 references, the aim of this review is to summarize current advances regarding the challenges of antibiotic drug discovery and the specific attributes of an ideal antibacterial drug (a prodrug or generally reactive compound with no specific target, broad-spectrum antibacterial activity, adequate penetration through the Gram-negative cell wall, activity in biofilms and in hard-to-treat infections, accumulation in macrophages, availability for oral administration, and for use in sensitive patient groups).
