Sci Rep 2024; 14:2708. [PMID: 38302627 PMCID: PMC10834397 DOI: 10.1038/s41598-024-53100-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 01/27/2024] [Indexed: 02/03/2024] Open
Abstract
Infections, such as mucormycosis, often result from inhaling sporangiospore present in the environment. Surprisingly, the extent of airborne Mucormycetes sporangiospore concentrations remains inadequately explored. This study aimed to assess the influence of UV radiation on microbial populations and Mucormycetes spore levels within a hospital environment in northern Iran. A comprehensive dataset comprising 298 air samples collected from both indoor and outdoor settings was compiled. The culture was conducted using Blood Agar and Dichloran Rose Bengal Chloramphenicol (DRBC) culture media, with Chloramphenicol included for fungal agents and Blood Agar for bacterial. Before UV treatment, the average count of Mucormycetes ranged from 0 to 26.4 ± 25.28 CFU m-3, fungal agents from 2.24 ± 3.22 to 117.24 ± 27.6 CFU m-3, and bacterial agents from 29.03 ± 9.9 to 359.37 ± 68.50 CFU m-3. Following UV irradiation, the averages were as follows: Mucormycetes ranged from 0 to 7.85 ± 6.8 CFU m-3, fungal agents from 16.58 ± 4.79 to 154.98 ± 28.35 CFU m-3, and bacterial agents from 0.38 ± 0.65 to 43.92 ± 6.50 CFU m-3. This study, notably marks the pioneering use of UV light to mitigate Mucormycetes spore counts and bacterial agents in northeastern Iran, contributing to the advancement of environmental health and safety practices in hospital settings.

Abstract
Since the first case of Severe Acute Respiratory Syndrome Coronavirus-2/Coronavirus Disease 2019 (SARS-COV-2/COVID-19) was discovered in Wuhan, China, it spread to vast limits globally and became a public health disaster, affecting nearly all countries around the globe. Along with mainstream medical treatment, alternative medicine desperately was the need of the hour for youngsters to manage their symptoms while being self-quarantined and ultimately to improve their chances of survival and recovery from COVID-19. Since the beginning of SARS-COV-2, few studies address the clinical-functional presentation of viral infection and management with physiotherapy for children. Major online electronic databases PubMed, PEDro, and Google Scholar were researched to identify, organize and commission the current review. To create a search strategy, Medical Subject Headings and Descriptors of Science and Health were utilized. The authors looked for other studies by screening the references list of the potentially pertinent papers. These computerized searches turned up studies and those studies' bibliographies with pertinent citations were examined. Personal protective equipment was a crucial component for protection and contact precaution. Following hypoxia, effective oxygen therapy is administered right away. When necessary, under the right circumstances, nasal high-flow oxygen therapy, non-invasive ventilation, lung-protective breathing methods, and prone positioning can be used. Children with SARS-CoV-2/COVID-19 may benefit from physiotherapy interventions with a focus on ventilatory management, airway clearance procedures, early activities, and mobilization.

Abstract
Background Successful implementation of patient safety plans in a hospital necessitates, among other things, the leadership capacity of nurse managers. Patient care delivery errors and adverse events continue to occur for a variety of reasons, including a failure to follow recommended patient safety strategies. Certain leadership styles foster interactions with healthcare staff, resulting in work environments that promote positive patient outcomes. It is unclear what nurse managers believe about the type of leadership style that drives patient safety. Aim The goal was to explore the nurse managers' perceptions of leadership styles as an impetus to patient safety. Setting The study was conducted at an academic hospital in the Tshwane District of Gauteng province. Methods A qualitative exploratory and descriptive contextual design was used. Semi-structured face-to-face interviews were conducted with 20 purposefully selected nurse managers. A thematic data analysis method was used to analyse data. Results Common leadership styles among nurse managers and challenges affecting the efficiency of nurse managers' leadership styles emerged as themes. Conclusion Nurse managers must have appropriate leadership styles to improve patient safety. Human and material resource shortages, as well as a lack of collaborative practice among healthcare professionals, jeopardise nurse managers' ability to maximise patient safety. Contribution The article provides insight into nurse managers' perceptions of leadership styles as critical to improving patient safety. Recommendations included the need for a structured ongoing leadership training programme to develop and strengthen the skills of newly appointed and existing nurse managers.

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.

Abstract
Background Healthcare workers (HCWs) play a vital role in delivering care and are frequently exposed to the risk of acquiring infections within the hospital setting. Around 15% of hospitalized patients suffer from these infections globally. However, the role and awareness of HCWs in the transmission of hospital-acquired infections (HAIs) or nosocomial infections is still unclear. This study aimed to evaluate the knowledge, attitude, and practices (KAP) toward high-risk microbial infections among HCWs on a global scale to identify measures to address this problem. Method A cross-sectional descriptive study was conducted between 2022 and 2023, with HCWs selected as the study population. Data concerning KAP were collected through a self-administered online survey questionnaire, using a nonprobability convenience sampling method. Descriptive statistics and regression analysis were used to analyze the data. Results A total of 743 HCWs from various countries participated in the study, with the majority of respondents being doctors (64.9%). Data were mainly obtained from Saudi Arabia (26.78%), Iraq (25.84%), India (15.7%), the United States of America (15.2%), and Africa (Sudan, Nigeria) (13.98%). The frequency of good KAP scores among physicians (KAP: 82.5, 80.66, and 70.5), nurses (KAP: 74.1, 73.07, and 88.7), medical practitioners (KAP: 87.2, 77.58, and 75.1), and technicians (KAP: 76.1, 74.38, and 89.6) were obtained as mentioned. With respect to experience, HCWs showed good KAP scores in 1-5 years (KAP: 82.4, 83.3, and 74.1), 5-10 years (KAP: 80.6, 74.54, 83), 10-20 years (KAP: 74.7, 79.1, and 82.7), and >20 years (KAP: 84.6, 78.8, and 82.8) categories. Conclusion This study suggests that HCWs have good KAP regarding infection prevention, but there is still room for improvement. Educational seminars and awareness programs can provide better adherence to barrier protection measures such as hand washing, use of gloves, and hand disinfection.

Abstract
A. baumannii imposes a great burden on medical systems worldwide. Surveillance of trends of antibiotic resistance provides a great deal of information needed for antimicrobial stewardship programmes nationwide. Clinical data from long-term, continuous surveillance on trends of antibiotic resistance of A. baumannii in Slovakia is missing. One hundred and forty-nine samples of A. baumannii were isolated over a period of four years. A panel of 19 antibiotics from seven antibiotic categories were tested for the bacterium's susceptibility. Resistance results were evaluated, and the significance of patterns was estimated using simple linear regression analysis. All isolates were more than 85% resistant to at least 13 out of the 19 tested antibiotics. A significant rise in resistance was recorded for aminoglycosides and imipenem from 2019 to 2022. Colistin and ampicillin-sulbactam have been the only antibiotics maintaining more than 80% efficacy on the bacterium to date. A significant rise in extensively drug-resistant (XDR) strains among carbapenem-resistant (CR) isolates has been recorded. Multidrug-resistance (MDR) among all A. baumannii isolates and XDR among CR strains of the bacterium have risen significantly in the last four years.

Abstract
INTRODUCTION Klebsiella pneumoniae is a major pathogen implicated in healthcare-associated infections. Extended-spectrum β-lactamase (ESBL) and carbapenemase-producing K. pneumoniae isolates are a public health concern. This study investigated the existence of some ESBL and carbapenemase genes among clinical isolates of K. pneumoniae in Southwest Nigeria and additionally determined their circulating clones. MATERIALS AND METHODS Various clinical samples from 420 patients from seven tertiary hospitals within Southwestern Nigeria were processed between February 2018 and July 2019. These samples were cultured on blood agar and MacConkey agar, and the isolated bacteria were identified by Microbact GNB 12E. All K. pneumoniae were confirmed by polymerase chain reaction (PCR) using the 16s rRNA gene. Antibiotic susceptibility testing (AST) was done on these isolates, and the PCR was used to evaluate the common ESBL-encoding genes and carbapenem resistance genes. Genotyping was performed using multi-locus sequencing typing (MLST). RESULTS The overall prevalence of K. pneumoniae in Southwestern Nigeria was 30.5%. The AST revealed high resistance rates to tetracyclines (67.2%), oxacillin (61.7%), ampicillin (60.2%), ciprofloxacin (58.6%), chloramphenicol (56.3%), and lowest resistance to meropenem (43.0%). All isolates were susceptible to polymyxin B. The most prevalent ESBL gene was the TEM gene (47.7%), followed by CTX-M (43.8%), SHV (39.8%), OXA (27.3%), CTX-M-15 (19.5%), CTX-M-2 (11.1%), and CTX-M-9 (10.9%). Among the carbapenemase genes studied, the VIM gene (43.0%) was most detected, followed by OXA-48 (28.9%), IMP (22.7%), NDM (17.2%), KPC (13.3%), CMY (11.7%), and FOX (9.4%). GIM and SPM genes were not detected. MLST identified six different sequence types (STs) in this study. The most dominant ST was ST307 (50%, 5/10), while ST258, ST11, ST147, ST15, and ST321 had (10%, 1/10) each. CONCLUSION High antimicrobial resistance in K. pneumoniae is a clear and present danger for managing infections in Nigeria. Additionally, the dominance of a successful international ST307 clone highlights the importance of ensuring that genomic surveillance remains a priority in the hospital environment in Nigeria.

Abstract
Intubated patients in intensive care units (ICUs) too frequently contract ventilator-associated pneumonia or Candida infections. Oropharyngeal microbes are believed to play an important etiologic role. This study was undertaken to determine whether next-generation sequencing (NGS) can be used to simultaneously analyze bacterial and fungal communities. Buccal samples were collected from intubated ICU patients. Primers targeting the V1-V2 region of bacterial 16S rRNA and the internal transcribed spacer 2 (ITS2) region of fungal 18S rRNA were used. V1-V2, ITS2, or mixed V1-V2/ITS2 primers were used to prepare an NGS library. Bacterial and fungal relative abundances were comparable for V1-V2, ITS2, or mixed V1-V2/ITS2 primers, respectively. A standard microbial community was used to adjust the relative abundances to theoretical abundance, and NGS and RT-PCR-adjusted relative abundances showed a high correlation. Using mixed V1-V2/ITS2 primers, bacterial and fungal abundances were simultaneously determined. The constructed microbiome network revealed novel interkingdom and intrakingdom interactions, and the simultaneous detection of bacterial and fungal communities using mixed V1-V2/ITS2 primers enabled analysis across two kingdoms. This study provides a novel approach to simultaneously determining bacterial and fungal communities using mixed V1-V2/ITS2 primers.

Abstract
Background During outbreaks of infectious diseases like COVID-19, the healthcare-associated infections (HCAIs) pose a burden on public health system. There are very limited data about infection prevention and control (IPC) implementation in the healthcare facilities of Pakistan. The aim of the study was to conduct assessment with the IPC Assessment Framework (IPCAF) tool in healthcare facilities of the least developed areas. Methods A cross-sectional survey was conducted in 12 tertiary level healthcare facilities (HCF) located in the least developed provinces of Pakistan. The facilities were selected through multistage cluster random methods. A well-structured questionnaire, the "IPCAF tool", was used for data collection. The IPCAF comprises eight sections with a 100 score of each section, thus with a maximum score of 800. The scores from 0 to 800 of the HCFs were divided into four gradual ratings through IPCAF, ie from inadequate to advanced. Results The median score of all facilities was 405, with a range from inadequate to advanced. One facility (8.3%) fell into the "inadequate" category with a score of 172.5; 5 (41.6%) facilities achieved "basic" category, another 5 (41.6%) being "intermediate", and only one (8.3%) hospital achieved "advanced" status. Region-wise median score of facilities of GB was 307.5, facilities in AJK scored 342.5, and a score of 520 was found for health facilities in KPK. The components of Education and Training, HCAIs Surveillance, and Multimodal Strategies achieved the lowest scores. Conclusion Most of the facilities have developed an IPC program with key focal persons and IPC committees, but did not have relevant education and training. IPC core capacities are being implemented. Equitable attention is required on all eight components of IPC in all facilities.

Mulec J, Skok S, Tomazin R, Letić J, Pliberšek T, Stopinšek S, Simčič S. Long-Term Monitoring of Bioaerosols in an Environment without UV and Desiccation Stress, an Example from the Cave Postojnska Jama, Slovenia. Microorganisms 2023; 11:microorganisms11030809. [PMID: 36985383 PMCID: PMC10053050 DOI: 10.3390/microorganisms11030809] [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: 02/24/2023] [Revised: 03/16/2023] [Accepted: 03/16/2023] [Indexed: 03/30/2023] Open
Abstract
A natural cave environment subject to regular human visitation was selected for aerobiological study to minimize the effects of severe temperature fluctuations, UV radiation, and desiccation stress on the aerobiome. The longer sampling period of bioaerosols, up to 22 months, was generally not associated with a proportionally incremental and cumulative increase of microbial biomass. The culture-independent biomass indicator ATP enabled quick and reliable determination of the total microbial biomass. Total airborne microbial biomass was influenced by human visitation to the cave, as confirmed by significantly higher concentrations being observed along tourist footpaths (p < 0.05). Airborne beta-glucans (BG) and lipopolysaccharide (LPS) are present in cave air, but their impact on the cave remains to be evaluated. Staphylococcus spp., as an indicator of human presence, was detected at all sites studied. Their long-term survival decrease is likely due to high relative humidity, low temperature, the material to which they adhere, and potentially natural elevated radon concentration. The most commonly recorded species were: S. saprophyticus, which was identified in 52% of the studied sites, S. equorum in 29%, and S. warneri in 24% of the studied sites. Only a few isolates were assigned to Risk group 2: S. aureus, S. epidermidis, S. haemolyticus, S. pasteuri, and S. saprophyticus.

Incidence, accuracy, and barriers of diagnosing healthcare-associated infections: a case study in southeast Iran. BMC Infect Dis 2023; 23:171.

Abstract
BACKGROUND Healthcare-associated infections (HAIs) are a threat to patients. Accurate surveillance is required to identify and prevent HAIs. To estimate the incidence rate, report the accuracy and identify the barriers of reporting HAIs using a mixed-method study. METHODS In this quantitative study, we externally evaluated the incidence rate and accuracy of the routine surveillance system in one of the main hospitals by an active follow-up of patients from September to December 2021. We used in-depth interviews with 18 experts to identify the barriers of the routine surveillance system. RESULTS Among 404 hospitalized patients, 88 HAIs were detected. The estimated rate of HAIs was 17.1 (95% Confidence Intervals 95: 14.1, 21.1) per 1000 patient-days follow-up. However, in the same period, 116 HAIs were reported by the routine surveillance system, but the agreement between the two approaches was low (sensitivity = 61.4%, specificity = 82.6%, negative predictive value = 89.7%, and positive predictive validity = 46.5%). The minimum and maximum positive predictive values were observed in urinary tract infection (32.3%) and surgical site infection (60.9%). The main barrier of reporting HAIs was lack of cooperation in reporting HAIs by infection control link nurses and laboratory supervisors. CONCLUSIONS The discrepancy between the longitudinal study findings and the routine surveillance might be related to the inaccessibility of the surveillance system to clinical information of patients. In this regard, decreasing the barriers, increasing the knowledge of infection control nurses and other nurses, as well as the development of hospital information systems are necessary.

Abstract
INTRODUCTION Healthcare-associated infections (HAIs) have become a serious public health problem. Despite the fact that implementing evidence-based infection control strategies could prevent HAIs and save billions of dollars, Ethiopia lacks national surveillance studies on the rate, economic, and clinical burden of HAIs. OBJECTIVE To assess the clinical and economic burden of HAIs in hospitalized patients at Ayder comprehensive specialized hospital. MATERIALS AND METHODS A prospective cohort study design was conducted in patients with and without HAIs. A review of medical records, interviews, and patient bills was used to extract necessary information. The patients in the two arms were matched based on age, sex, Charlson comorbidity index, and ward type. Measurable factors were compared between infected and uninfected patients using the paired ttest or McNemar's test, as appropriate. Logistic regression was used to identify predictors of in-hospital mortality. Stata 14.1 was used to conduct all analyses. RESULTS A total of 408 patients, 204 with HAIs and 204 without HAIs were included in the study. In-hospital mortality was higher in patients with HAI (14.7% vs 7.8%, P = 0.028). Patients with HAI stayed an average of 8.3 days longer than controls (18.85 vs 10.59, P<0.001). The average direct medical costs for patients with HAI were 3033 Ethiopian birrs (ETB) higher than controls (4826 vs 1793, P<0.001). The presence of HAIs (AOR: 2.22, 95% CI: 1.13-4.39) and admission to intensive care units (AOR: 3.39, 95% CI: 1.55-7.40) were significant predictors of in-hospital mortality. CONCLUSION HAIs have a significant impact on in-hospital mortality, the length of extra hospital stays, and extra costs for medical care. Patients admitted to intensive care units and those with HAIs were found to be significant predictors of in-hospital mortality. Interventions must be implemented to prevent HAIs, especially in patients admitted to intensive care units.

Abstract
BACKGROUND Candida infections have become one of the most common causes of morbidity and mortality in paediatric ICUs, especially following complex surgeries, all over the world. Therefore, we conducted a 5-year analysis of Candida bloodstream infections in our tertiary paediatric cardiovascular surgery ICU. METHODS One thousand nine hundred and thirty four children, 0-16-year-old, who underwent paediatric cardiovascular surgery between January 2016-June 2021 were enrolled in this retrospective study. Blood cultures obtained from 1056 patients, who needed mechanical ventilation and indwelling devices longer than 5 days and had the signs of infection according to Center for Disease Control criteria, were evaluated. The isolated pathogens were recorded. 137 with Candida bloodstream infections were reanalysed for their age, weight, cardiac pathologies, duration of mechanical ventilation, hospitalisation and antibiotic use. RESULTS One hundred and thirty-seven out of one thousand and fifty six patients (12.9%) had Candida growth in their blood cultures. C. albicans (n: 50, 36.5%), C. parapsilosis (n: 20, 14.6%), C. tropicalis (n: 8, 5.8%), C. glabrata (n: 5, 3.7%), and other non-albicans Candida species (n: 54, 39.4%) were isolated. The patients with Candida bloodstream infections had lower age, longer duration of mechanical ventilation, longer length of hospital stay and antibiotic use (p-values<0.05). They had cardiac pathologies as atrioventricular septal defect (18.9%), transposition of great arteries (17.6%), tetralogy of Fallot (12.4%), transposition of great arteries + double outlet right ventricle, or total anomalous pulmonary venous return + atrioventricular septal defect (37.9%), and others. The Candida bloodstream infections mortality was 11.6% (16/137). CONCLUSION The most common cause of Candida bloodstream infections in the last five years in our paediatric cardiovascular surgery ICU was non-albicans Candida species. Prolonged mechanical ventilation, hospitalisation and antibiotic use, low age, and weight were found as the main risk factors that raise the morbidity and mortality rates of Candida bloodstream infections.

Abstract
Biofilm formation and capsule production are known microbial strategies used by bacterial pathogens to survive adverse conditions in the hospital environment. The relative importance of these strategies individually is unexplored. This project aims to compare the contributory roles of biofilm formation and capsule production in bacterial survival on hospital surfaces. Representative strains of bacterial species often causing hospital-acquired infections were selected, including Acinetobacter baumannii, Klebsiella pneumoniae, Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa. The importance of biofilm formation and capsule production on bacterial survival was evaluated by comparing capsule-positive wild-type and capsule-deficient mutant strains, and biofilm and planktonic growth modes respectively, against three adverse hospital conditions, including desiccation, benzalkonium chloride disinfection and ultraviolet (UV) radiation. Bacterial survival was quantitatively assessed using colony-forming unit (CFU) enumeration and the 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) assay and qualitatively by scanning electron microscopy (SEM). Correlations between capsule production and biofilm formation were further investigated. Biofilm formation contributed significantly to bacterial survival on hospital surface simulators, mediating high resistance to desiccation, benzalkonium chloride disinfection and UV radiation. The role of capsule production was minor and species-specific; encapsulated A. baumannii but not K. pneumoniae cells demonstrated slightly increased resistance to desiccation, and neither showed enhanced resistance to benzalkonium chloride. Interestingly, capsule production sensitized K. pneumoniae and A. baumannii to UV radiation. The loss of capsule in K. pneumoniae and A. baumannii enhanced biofilm formation, possibly by increasing cell surface hydrophobicity. In summary, this study confirms the crucial role of biofilm formation in bacterial survival on hospital surfaces. Conversely, encapsulation plays a relatively minor role and may even negatively impact bacterial biofilm formation and hospital survival.

Abstract
The extensive use of antibiotics and vaccines against microbial infections can result in long-term negative effects on humans and the environment. However, there are a number of plants that have antimicrobial effects against various disease-causing microbes such as bacteria, viruses, and fungi without negative side effects or harm to the environment. In this regard, four particular plants- Capsicum, Nigella sativa, Musa paradisiaca L., and Citrus limetta have been widely considered due to their excellent antimicrobial effect and ample availability. In this review, we discuss their antimicrobial effects due to the presence of thymoquinone, p-cymene, pinene, alkaloids, limonene, camphene, and melanin. These antimicrobial compounds disrupt the cell membrane of microbes, inhibit cellular division, and form biofilm in bacterial species, eventually reducing the number of microbes. Extraction of these compounds from the respective plants is carried out by different methods such as soxhlet, hydro-distillation, liquid-liquid extraction (LLE), pressurized liquid extraction (PLE), solid-phase extraction (SPE), supercritical fluid extraction (SFE), pulsed electric field (PEF), microwave-assisted extraction (MAE), enzyme-assisted extraction (EAE), ultrasound-assisted extraction (UAE), and high-voltage electrical discharge. Suitable selection of the extraction technique highly depends upon the associated advantages and disadvantages. In order to aid future study in this field, this review paper summarizes the advantages and disadvantages of each of these approaches. Additionally, the discussion covers how antimicrobial agents destroy harmful bacteria. Thus, this review offers in-depth knowledge to researchers on the antibacterial properties of Capsicum, Nigella sativa, Musa paradisiaca L. peels, and Citrus limetta.

Abstract
Rapid transmission of infectious microorganisms such as viruses and bacteria through person-to-person contact has contributed significantly to global health issues. The high survivability of these microorganisms on the material surface enumerates their transmissibility to the susceptible patient. The antimicrobial coating has emerged as one of the most interesting technologies to prevent growth and subsequently kill disease-causing microorganisms. It offers an effective solution a non-invasive, low-cost, easy-in-use, side-effect-free, and environmentally friendly method to prevent nosocomial infection. Among antimicrobial coating, zinc oxide (ZnO) stands as one of the excellent materials owing to zero toxicity, high biocompatibility to human organs, good stability, high abundancy, affordability, and high photocatalytic performance to kill various infectious pathogens. Therefore, this review provides the latest research progress on advanced applications of ZnO nanostructure-based antibacterial coatings for medical devices, biomedical applications, and health care facilities. Finally, future challenges and clinical practices of ZnO-based antibacterial coating are addressed.

Abstract
Many studies show that photodynamic inactivation (PDI) is a powerful tool for the fight against pathogenic, multi-resistant bacteria and the closing of hygiene gaps. However, PDI studies have been frequently performed under standardized in vitro conditions comprising artificial laboratory settings. Under real life conditions, however, PDI encounters substances like ions, proteins, amino acids, and fatty acids, potentially hampering the efficacy PDI to an unpredictable extent. Thus, we investigated PDI with the phenalene-1-one based photosensitizer SAPYR against Escherichia coli and Staphylococcus aureus in the presence of calcium or magnesium ions, which are ubiquitous in potential fields of PDI applications like in tap water or on tissue surfaces. The addition of citrate should elucidate the potential as a chelator. The results indicate that PDI is clearly affected by such ubiquitous ions depending on its concentration and the type of bacteria. The application of citrate enhanced PDI especially for Gram-negative bacteria at certain ionic concentrations (e.g. CaCl2 or MgCl2 : 7.5 to 75 mmol l-1 ). Citrate also improved PDI efficacy in tap water (especially for Gram-negative bacteria) and synthetic sweat solution (especially for Gram-positive bacteria). In conclusion, the use of chelating agents like citrate may facilitate the application of PDI under real life conditions.

Abstract
Due to resistance and scarcity of treatment options, nosocomial Acinetobacter baumannii infections are associated with significant fatality rates. We investigated the factors contributing to infection-related deaths to develop tailored stewardship interventions that could reduce these high mortality rates. We reviewed the medical records of adult inpatients with A. baumannii infections over two years. Patient demographics and clinical data were collected and statistically analyzed. The study included 321 patients with positive A. baumannii microbiological cultures, with respiratory infections accounting for 58.6%, soft tissues 29.3%, bacteremia 8.6%, urine 2.1%, and others 1.4%. The study population’s median (IQR) age was 62.6 (38.9−94.9) years, and hospital stay was 20 (9.5−40) days. Statistical analysis revealed that various risk factors contribute significantly to high in-hospital all-cause mortality (44%), as well as 14-day and 28-day mortality rates. Deaths increased by a factor of 1.04 with every additional year of age (p = 0.000), admission to the critical care unit (p = 0.000, OR: 2.86), and patients admitted with an infectious diagnosis had nearly three times the mortality rate as those admitted with other diagnoses (p = 0.000, OR: 3.12). Male gender (p < 0.001, OR: 2.14), any comorbid conditions (p = 0.000, OR: 5.29), prolonged hospitalization (>7 days) (p = 0.023, OR: 1.98), and hospital acquisition of infection (p = 0.027, OR: 1.68) were among the most significant predictors of mortality. All variables were investigated for their impact on all-cause, 14-day, and 28-day mortality rates. Improving multidisciplinary infection control practices, regular disinfection of patient care equipment, and optimal intubation practice that avoids unnecessary intubation are necessary interventions to reduce infection-related mortality rates. Better antibiotic selection and de-escalation, shorter hospital stays whenever possible, prompt medical stabilization of comorbid conditions, and fewer unnecessary admissions to critical care units will all lead to improved outcomes.

Abstract
G6PD deficiency is a genetic disease that weakens the immune system and renders affected individuals susceptible to infections. In the Sultanate of Oman resides a high number of recorded G6PD cases due to widespread consanguineous marriage, which may reach 25% of the population. We studied the infection patterns and risk factors for mortality to provide antimicrobial stewardship recommendations for these patients. After obtaining ethical approval, a registry of recorded cases was consulted retrospectively to include G6PD-deficient adult patients admitted to Suhar hospital over 5 years with microbiologically confirmed infections. Patient demographics, health-related information, infection causes, treatment, and clinical outcomes were studied. Data were analyzed to describe infection patterns and risk factors. Several variables, including underlying comorbidities and hospitalization details, such as length of stay, admission to critical care unit, blood transfusion, or exposure to an invasive procedure, were statistically associated with the acquisition of multidrug-resistant and hospital-acquired infections. Meanwhile, these infections were associated with a high mortality rate (28%), significantly associated with the patient’s health status and earlier exposure to antimicrobial treatment due to previous bacterial infection. The high prevalence of G6PD deficiency among the Omani population should alert practitioners to take early action when dealing with such cases during infection that requires hospitalization. Strict infection control measures, Gram-negative empiric coverage, hospital discharge as early as possible, and potent targeted antimicrobial therapy in this patient population can ameliorate the treatment outcomes and should be emphasized by the antimicrobial stewardship team.

Abstract
Hospital surfaces are heavily contaminated with bacteria, which are a potential source of nosocomial infections. This study was undertaken to identify bacterial communities isolated from neglected hospital surfaces after cleaning routine in a Algerian public hospital. Screening of bacterial contamination in patient bed (PB), reception land-line phones (TF), door handles (DH) and medical equipment (ME) during five months generated 108 inocula. Isolates obtained were identified based on biochemical characteristics and confirmed by analysis of 16S rRNA sequences. Statistical analysis was performed to reveal possible relationship between bacterial diversity and swabbed surfaces. Our findings showed a high prevalence of bacteria in various hospital surfaces, reaching (65.25%), where a highest contaminated surface was the PB (47.22%) and a lowest contaminated was TF (5.55%). Gram negative bacteria were the dominant group (62.03%) mainly represented by Entrobacteriaceae (42.59%), whereas Staphylococcus aureus belonging to Gram positive was the main expanded pathogen with (15.74%).

Management of Ventilator-Associated Pneumonia: Quality Assessment of Clinical Practice Guidelines and Variations in Recommendations on Drug Therapy for Prevention and Treatment. Front Pharmacol 2022; 13:903378. [PMID: 35668946 PMCID: PMC9163435 DOI: 10.3389/fphar.2022.903378] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 04/29/2022] [Indexed: 11/21/2022] Open
Abstract
Purpose: To assess the quality of clinical practice guidelines (CPGs) related to drug therapy for prevention and control of ventilator-associated pneumonia (VAP) and compare the differences and similarities between recommendations. Methods: Electronic databases (including PubMed, Cochrane library, Embase, Web of Science), guideline development organizations, and professional societies were searched to identify CPGs for VAP from 20 January 2012 to 20 January 2022. The Appraisal of Guidelines Research & Evaluation (AGREE) II instrument was used to evaluate the quality of the guidelines. The recommendations on drug therapy for prevention and treatment for each guideline were extracted, and then a descriptive synthesis was performed to analyze the scope/topic, and consistency of the recommendations. Results: Thirteen CPGs were included. The median score and interquartile range (IQR) in each domain are shown below: scope and purpose 72.22% (63.89%,83.33%); stakeholder involvement 44.44% (38.89%,52.78%); rigor of development 43.75% (31.25%,57.29%); clarity and presentation 94.44% (77.78%,94.44%); applicability 20.83 (8.34%,33.34%) and editorial independence 50% (33.33%,66.67%). We extracted 21 recommendations on drug therapy for prevention of VAP and 51 recommendations on drugs used for treatment. Some controversies remained among the included guidelines. Conclusion: There is considerable variability in the development processes and reporting of VAP guidelines. Despite many similarities, the recommendations still had some inconsistencies in the details. For the prevention and treatment of VAP, local microbial epidemiology and antibiotic sensitivity must be considered, and recommendations should be regularly revised as new evidence emerges.

[PMID: 35379595 DOI: 10.1016/j.idh.2022.03.002] [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: 10/27/2021] [Revised: 02/22/2022] [Accepted: 03/06/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND In Australia, Patient Service Assistants are an integral part of all health care settings, yet there is a paucity of studies considering their understandings and perceptions of their role about infection prevention and control. The aim in this study was to explore haematology Personal Service Assistants' experience, understanding and perceptions of their role in improving patient safety through environmental cleaning. METHODS A qualitative exploratory descriptive design was utilised to collect data from cleaning staff via focus groups. Three semi-structured focus groups were conducted. RESULTS Seven Patient Service Assistants participated in the study out of 11 employed. Two key themes emerged from the thematic analysis: (1) Playing a major role in Infection Prevention and Control, and (2) prioritising good interpersonal relationships over promoting infection prevention and control. Patient Service Assistants emphasised the importance of their involvement in keeping the ward clean, including patients' rooms and surroundings, to prevent cross infection. Most participants underlined the dilemmas they faced when visitors and/or informal cleaning employees or casual ward staff did not adhere to ward infection prevention and control norms. CONCLUSION Patient Service Assistants were employing key infection prevention and control principles in their ward cleaning routine, with the aim of achieving a safer patient environment although they were reluctant to challenge observed practice deviations. The role of Patient Service Assistants highlights the widely held misconception that patient safety is solely dependent on healthcare workers.

Abstract
Background: Infection control systems allow the healthcare facility to detect, manage, prevent and control the infection or risk of infection. It helps to improve healthcare quality by allowing hospital infection control (HIC) team to focus on prevention and intervention efforts during the outbreaks. Objectives: To design, develop and implement an automated HIC surveillance Toolkit for Infection Prevention and Control Department based on user requirements. Methods: This study was carried out in a multi-speciality hospital in Southern India. The study was carried out in four phases; the first phase included the observation of current documentation practice of Infection Prevention and Control Department. During the second phase, a formal discussion was conducted with the infection control team to collect the data to add to the HIC surveillance toolkit. The third phase included the design and development of the toolkit using ASP.NET and Standard Query Language (SQL) database server. During the fourth phase, a prospective cross-sectional survey was conducted to assess the end-user satisfaction towards the Toolkit using a structured and validated checklist based on 5-point Likert scale from extremely satisfied to not satisfied (score 5–1). Results: Based on the observation of existing documentation and reporting practice, a discussion was carried out with the infection control team to identify the templates to be added to the toolkit. Once identified, a web-based toolkit was designed and developed using ASP.NET and stored using SQL database server. The developed toolkit was implemented in the hospital and provided to the HIC team to use. The finding of the assessment of 15 features of HIC surveillance toolkit indicated that the end-users were very satisfied with the support of toolkit in documenting and reporting of infection-related data. Conclusion: HIC surveillance toolkit, allows the HIC team to capture, store, manage data, compare, and calculate the infection control rate and compliance rate. It also increases the ease of surveillance and reporting. It aids in reducing hospital-acquired infection (HAI) rates, simplifies the workflow of HIC and improves healthcare quality.

Abstract
Background Infections of sterile body fluids are susceptible to serious invasive bacterial infections and critical, with high morbidity and sequelae risk. This study has not been conducted previously in eastern Ethiopia. Objective The present study was designed to determine the bacterial profile, associated factors, and their susceptibility to antimicrobial agents of isolates among patients with sterile body fluids at Hiwot Fana Specialized University Hospital, Harar, Eastern Ethiopia. Methods Hospital-based cross-sectional study was conducted from April to June 2021 among 204 patients selected using a convenient sampling technique. Data were collected using a pretested structured questionnaire. All consenting patients submitting body fluid specimens for testing at the clinical laboratory were included and analyzed using standard microbiology methods. Antimicrobial susceptibility testing was performed using the disk diffusion method and interpreted as per Clinical and Laboratory Standards Institute guidelines. Data were double entered into Epi data version 4.6, exported, and analyzed using Statistical Package for Social Science version 25. Bivariate and multivariable logistic regressions were used to assess the association between outcome and predictor variables. P-value <0.05 was considered to be statistically significant. Results The overall prevalence of bacteria among different sterile body fluid samples was 16.7% (95% CI: 12–22%). Most of the bacterial isolates (70.6%) were Gram-negative bacteria, mainly K. pneumoniae (26.5%) and E. coli (20.6%). Multidrug resistance was identified in 76.5% of the isolates. Being inpatient (AOR = 3.59; 95% CI: 1.52, 8.51) and turbid appearance (AOR = 4.35; 95% CI: 1.67, 11.29) were significantly associated with culture growth rate. Conclusion The prevalence of bacterial isolates in this study comprises about 17%. Gram-negative bacteria, particularly K. pneumoniae and E. coli, were the major etiologic agents. Being inpatient and the turbid appearance of the specimen were significantly associated with the culture-positive result. Significant numbers of multidrug-resistant bacteria were isolated, mainly against beta-lactams. Therefore, culture and susceptibility testing should be an integral part of the laboratory investigation.

Abstract
BACKGROUND Multidrug resistance (MDR) is a global problem that require multifaceted effort to curb it. This study aimed to evaluate the antibiotic susceptibility patterns of routinely isolated bacteria at Livingstone Central Hospital (LCH). METHODS A retrospective study was performed on all isolated organisms from patient specimens that were processed from January 2019 to December 2021. Specimens were cultured on standard media and Kirby-Bauer disc diffusion method was employed for susceptibility testing following the Clinical and Laboratory Standard Institute's recommendations. RESULTS A total of 765 specimens were processed and only 500 (65.4%) met the inclusion criteria. Of the 500, 291(58.2%) specimens were received from female and from the age-group 17-39 years (253, 50.6%) and 40-80 years (145, 29%) in form of blood (331, 66.2%), urine (165, 33%) and sputum (4, 0.8%). Amongst the bacterial isolates, Staphylococcus aureus (142, 28.4%) was the commonest followed by Escherichia coli (91, 18.2%), and Enterobacter agglomerans (76, 15.2%), and Klebsiella pneumoniae (43, 8.6%). The resistance pattern revealed ampicillin (93%) as the least effective drug followed by oxacillin (88%), penicillin (85.6%), co-trimoxazole (81.5%), erythromycin (71.9%), nalidixic acid (68%), and ceftazidime (60%) whereas the most effective antibiotics were imipenem (14.5%), and piperacillin/tazobactam (16.7%). The screening of methicillin resistant Staphylococcus aureus (MRSA) with cefoxitin showed 23.7% (9/38) resistance. CONCLUSION Increased levels of MDR strains and rising numbers of MRSA strains were detected. Therefore, re-establishing of the empiric therapy is needed for proper patient management, studies to determine the levels of extended spectrum beta lactamase- and carbapenemase-producing bacteria are warranted.

Abstract
Supplemental Digital Content is available in the text. IMPORTANCE: Prognostication following ICU admission can often be determined based on known risk factors, including demographics and illness severity; however, little is known about outcomes of patients deemed to be “low-risk” at the time of hospital admission who subsequently are admitted to the ICU. OBJECTIVES: The objectives of this study were to determine the characteristics, outcomes, and costs for patients requiring ICU admission despite having lower predicted mortality when they were admitted to the hospital. DESIGN, SETTING, AND PARTICIPANTS: In this historical cohort study, we used a prospectively maintained ICU registry that included all ICU admissions to The Ottawa Hospital for patients 18 years or older from January 2011 to December 2016. We classified patients as low-risk using the Hospital-patient 1-year Mortality Risk at admission score, a hospital admission score validated to predict 1-year mortality. MAIN OUTCOMES AND MEASURES: The primary outcome was inhospital mortality. Secondary outcomes included adverse events, resource utilization, and costs. RESULTS: Of the 17,173 total ICU patients, 3,445 (20.1%) were classified as low-risk at hospital admission. Low-risk patients were younger (48.7 vs 67.5 yr; p < 0.001) and had a lower Multiple Organ Dysfunction Score (2.37 vs 4.14; p < 0.001). Mortality for low-risk patients was significantly lower than for non–low-risk patients (4.1% vs 25.4%; p < 0.001). For low-risk patients, multivariable logistic regression showed mortality was independently associated with older age (odds ratio, 1.02 per 1 yr; 95% CI, 1.00–1.03 per 1 yr), Multiple Organ Dysfunction Score (odds ratio, 1.42 per 1 point; 95% CI, 1.31–1.54 per 1 point), fluid management adverse events (odds ratio, 2.84; 95% CI, 1.29–6.25), hospital-acquired infections (odds ratio, 1.60; 95% CI, 1.02–2.51), and mechanical ventilation (odds ratio, 1.98; 95% CI, 1.20–3.26). CONCLUSIONS AND RELEVANCE: Despite their robust premorbid status, low-risk patients admitted to the ICU had significant inhospital mortality. Fluid management adverse events, hospital-associated infections, multiple organ dysfunction, and mechanical ventilation are important prognostic factors for low-risk patients.

Abstract
BACKGROUND AND AIMS Acinetobacter baumannii is among the most concerning cause of nosocomial infections due to its high level of antibiotic resistance and high mortality. The aim of this study was to determine the role of efflux pumps in resistance of A. baumannii strains to three disinfectants, including MICROZED ID-MAX, NANOSIL D2, and OPIDEX OPA. METHODS Twenty-eight environmental and clinical isolates of A. baumannii were collected from selected hospitals of central Iran. The minimum inhibitory concentrations of the disinfectants were determined and real time reverse transcriptase-PCR was performed to investigate the expression level of qacEΔ1, amvA, abeM, and adeB efflux pump genes. RESULTS Considering both clinical and environmental isolates, there was a significant difference in the mean expression level of qacEΔ1 gene between susceptible and resistant strains to MICROZED ID-MAX disinfectant, of amvA and abeM genes between susceptible and resistant strains to NANOSIL D2 disinfectant and of abeM gene in susceptible and resistant strains to OPIDEX OPA disinfectant (all P ˂ .05). The expression levels of abeM and amvA genes were higher in the environmental isolates that were resistant to NANOSIL D2 disinfectant compared to those that were susceptible (P ˂ .05). CONCLUSIONS This study provided evidence for the role of abeM and amvA genes in the resistance of environmental isolates to disinfectants, particularly hydrogen peroxide derivatives.

Abstract
The novel coronavirus disease 2019 (COVID-19) pandemic has brought to light the role of environmental hygiene in controlling disease transmission. Healthcare facilities are hot spots for infectious pathogens where physical distancing and personal protective equipment (PPE) are not always sufficient to prevent disease transmission. Healthcare facilities need to consider adjunct strategies to prevent transmission of infectious pathogens. In combination with current infection control procedures, many healthcare facilities are incorporating ultraviolet (UV) disinfection into their routines. This review considers how pathogens are transmitted in healthcare facilities, the mechanism of UV microbial inactivation and the documented activity of UV against clinical pathogens. Emphasis is placed on the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) as well as multidrug resistant organisms (MDROs) that are commonly transmitted in healthcare facilities. The potential benefits and limitations of UV technologies are discussed to help inform healthcare workers, including clinical studies where UV technology is used in healthcare facilities.

Abstract
Introduction: Hospital-acquired infection (HAI) rates were reported to have declined in healthcare settings during the Covid-19 pandemic. Needless to mention that HAI is of paramount interest and relevance to a primary care physician who need to care from womb to tomb inside pandemic. Objectives: This study was conducted to find the impact of Covid-19 pandemic on the four parameters of HAIs, namely, catheter-associated urinary tract infections (CAUTI), central-line-associated bloodstream infections (CLABSI), ventilator-associated pneumonia (VAP) and surgical site infections (SSIs) with hand hygiene compliance rates among healthcare workers. Materials and Methods: This retrospective data mining was undertaken in a 700 bed multispecialty teaching hospital in the Eastern India which was a Government of Bihar approved speciality Covid Care Hospital. Data from the monthly routine infection control monitoring and surveillance activities was collated from January 2019 to December 2020. Control charts with upper and lower control limit set at mean ± 1 SD were used to monitor monthly trends of HAIs. Results: The CAUTI rates reduced by 28.01%; the CLABSI rates declined by 37.61%, the SSI rates reduced by 62.39%, while the highest VAP rates were reported in November 2019 (1.9 per 1000 ventilator days). The hand hygiene compliance rates from January 2019 to December 2020 among different healthcare staffs showed a sharply rising trend. Conclusion: Covid-19 pandemic highlighted paramount importance regarding compliance to hand hygiene and implementation of standard infection control practices as recommended by World Health Organisation and Centres for Diseases Control and Prevention (CDC), which can drastically reduce range of HAIs.

[PMID: 34707380 PMCID: PMC8544126 DOI: 10.2147/idr.s337611] [Citation(s) in RCA: 75] [Impact Index Per Article: 25.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Accepted: 10/13/2021] [Indexed: 12/15/2022] Open
Abstract
Infections due to multidrug-resistant Enterobacteriaceae have become major international public health problem due to the inadequate treatment options and the historically lagged pace of development of novel antimicrobial drugs. Inappropriate antimicrobial use in humans and animals coupled with increased global connectivity aided to the transmission of drug-resistant Enterobacteriaceae infections. Carbapenems are the medications of choice for extended-spectrum beta-lactamase and AmpC producers, but alternatives are currently needed because carbapenem resistance is increasing globally. This review pointed to discuss emerging drug-resistant Enterobacteriaceae, its epidemiology and novel treatment options for infections, which date back from 2010 to 2019 by searching Google Scholar, PubMed, PMC, Hinari and other different websites. The occurrence of carbapenem-resistant Enterobacteriaceae is reported worldwide with great regional variability. The rise of carbapenem-resistant Enterobacteriaceae poses a threat to all nations. Enzyme synthesis, efflux pumps, and porin mutations are the main methods by which Enterobacteriaceae acquire resistance to carbapenems. The major resistance mechanism among these is enzyme synthesis. Most carbapenem resistance is caused by three enzyme groups: Klebsiella pneumoniae carbapenemase (Ambler class A), metallo-ß-lactamases (Ambler class B), and oxacillinase-48 (Ambler class D). Ceftazidime–avibactam, which was newly licensed for carbapenemase producers, is the most common treatment option for infections. Meropenem–vaborbactam, imipenem–relebactam, plazomicin, cefiderocol, eravacycline, and aztreonam–avibactam are recently reported to be active against carbapenem-resistant Enterobacteriaceae; and are also in ongoing trials for different populations and combinations with other antibacterial agents. Overall, treatment must be tailored to the patient’s susceptibility profile, type and degree of infection, and personal characteristics.

Abstract
BACKGROUND AND OBJECTIVES Comparing outcome measures in health care is a relatively common practice. Reports are designed to compare hospital infection rates in an accurate and fair manner. The current methodology used by New York State (NYS) has some limitations and flaws. This research provides a methodology that overcomes these limitations and flaws. METHODS The methodology is a replication study using data from NYS and includes the use of the binomial and Poisson distribution to calculate upper tail (UTP) and lower tail probabilities (LTP). The UTP is used to screen for poor performers, and the LTP is used to screen for good performers. RESULTS The results we obtained using the tail probability method compared with NYS's confidence interval approach are similar across all health care-associated infection (HAI) categories but have the benefit of allowing for the analysis of any hospital regardless of the number of procedures, number of central line-days, or number of patient-days. In addition, we provide an evaluation of a hospital's performance over time where we identified hospitals that were consistently performing poorly and others consistently performing well. CONCLUSION Identifying hospitals that are consistently performing poorly and hospitals consistently performing well will allow administrators and clinicians to focus their efforts including budgetary to where improvements are needed. Patient care and the reduction of HAIs are a priority for health care institutions. While the results are similar to those reported by NYS, this approach can be used more comprehensively and can be interpreted more easily by administrators and practitioners. Health care administrators and clinicians may find the information useful to address infection rates. Hospitals consistently performing well may be used as a benchmark.

Abstract
AIM The purpose of this descriptive qualitative study was to evaluate nurses' views of implementation evidence-based fall prevention interventions. METHODS The study was conducted with participation of nurses who worked in a training and research hospital after evidence-based fall prevention interventions had been implemented. Interviews were done with 17 nurses who participated in all training courses. RESULTS The evaluation of the interventions was examined, and three themes were extracted through analysis: 'effectiveness of training programme', 'barriers' and 'suggestions'. CONCLUSION Nurses emphasized that evidence-based fall prevention interventions are usable in hospital, but team collaboration and administrative support are required for better outcomes. IMPLICATIONS FOR NURSING MANAGEMENT The study result shows that fall prevention interventions should be introduced to all health care professionals, through the use of various training methods. Training should be given to patients and their caregivers, and barriers that nurses stated like understaffing, lack of materials and tools that ensure patient safety and internet (research/scientific information) access restriction should be reduced.

Abstract
Background — Nosocomial infection (NI) is among the most common and serious challenges in a healthcare system. Health workers and medical students play an important role in prevention of NI. Despite advances in the field of medicine in Kazakhstan, low detection rate of NIs remains unchanged, which could be due to a lack of awareness of the standard precautions for infection control among medical students and health workers. This study is aimed at examining knowledge and judgments on NIs among medical and non-medical students. Material and Methods — We conducted a cross-sectional paper-based survey to examine the knowledge and judgments about the standard precautions for NI among medical and non-medical students. Data collection took place between September 21 and December 20, 2017. Results — The study enrolled 2,817 students. The mean overall score (±SD) was 2.045±1.29. Medical students had a better mean overall score (2.113) than non-medical students (1.785; p<0.001). Awareness of the standard preventive measures was increasing with a year of study, but still just one-third of year 5 medical students were aware of standard prevention (36.3% vs. 17.4% for non-medical students; p<0.001). Conclusion — The overall score of our survey indicated inadequate knowledge and awareness of the guidelines on infection prevention and control among both medical and non-medical students. In order to improve patient safety and welfare, the courses on infection control should be introduced into the curricular of medical universities in Kazakhstan.

Abstract
Since the discovery of coronavirus disease 2019 (COVID-19), which started in Wuhan, China, the epidemic has not only swept through China but also spread throughout the world in spite of the concerted attempts from the governments to contain it. Thus, prevention and control of COVID-19 infection is very effective in ensuring the safety of medical specialists, health care workers, and patients. Audiology clinics are also crucial in the fight against the infection epidemic, as audiologists provide their diagnostic and rehabilitative services in an environment with different contaminated objects that come in either direct or indirect contact with multiple patients. The current article explains the importance of infection control in audiology and priority setting for audiologic evaluation in COVID-19 pandemic.

Abstract
Nosocomial infections appear in patients treated in hospital, which are not the initial cause of admission. A retrospective study concerning nosocomial infections was conducted to provide data about the amount, frequency and types of nosocomial infections in the rehabilitation ward in the Orthopaedics and Rehabilitation Clinic of Lublin. The study was conducted on a group of 49 patients that were admitted or transferred to the ward over a period of 20 months in the years 2018–2020. The patients and therefore the infections were divided by age, sex, time of hospitalization and the underlying disease. The study also provided data about the most frequent infection types in these patients, as well as the most commonly used drugs to treat those infections. The results showed that in fact all of the examined factors have an impact on the frequency of nosocomial infections appearance rates. Furthermore, results in the study showed that factors examined by the study also have an impact on what type of infection was present in these groups of patients.

Abstract
BACKGROUND Hospital-acquired conditions (HACs) have a direct impact on value, as they decrease quality and increase costs. Numerous interventions have been tried, including nutrition support therapy, with unknown effect on value. Therefore, a value analysis of nutrition support therapy on HACs was performed. METHODS An extensive literature search was performed. Using the Medicare Parts A and B Claims 5% Sample data set, analytic claims modeling was conducted. RESULTS The search identified 1099 studies, with eight meeting the inclusion criteria. All studies were performed on adult critically ill patients and focused on HA infections (HAIs) as the HAC. One study underwent Medicare claims modeling and revealed nutrition therapy has the potential of saving at least $104 million annually in Medicare patients with HAIs. CONCLUSION Nutrition support therapy has the potential to reduce costs of Medicare spending in respect to HAIs.

Abstract
The emerging problem of the antibiotic resistance development and the consequences that the health, food and other sectors face stimulate researchers to find safe and effective alternative methods to fight antimicrobial resistance (AMR) and biofilm formation. One of the most promising and efficient groups of materials known for robust antimicrobial performance is noble metal nanoparticles. Notably, silver nanoparticles (AgNPs) have been already widely investigated and applied as antimicrobial agents. However, it has been proposed to create synergistic composites, because pathogens can find their way to develop resistance against metal nanophases; therefore, it could be important to strengthen and secure their antipathogen potency. These complex materials are comprised of individual components with intrinsic antimicrobial action against a wide range of pathogens. One part consists of inorganic AgNPs, and the other, of active organic molecules with pronounced germicidal effects: both phases complement each other, and the effect might just be the sum of the individual effects, or it can be reinforced by the simultaneous application. Many organic molecules have been proposed as potential candidates and successfully united with inorganic counterparts: polysaccharides, with chitosan being the most used component; phenols and organic acids; and peptides and other agents of animal and synthetic origin. In this review, we overview the available literature and critically discuss the findings, including the mechanisms of action, efficacy and application of the silver-based synergistic antimicrobial composites. Hence, we provide a structured summary of the current state of the research direction and give an opinion on perspectives on the development of hybrid Ag-based nanoantimicrobials (NAMs).

Abstract
Infants born before 28 weeks are at risk of contracting healthcare-associated infections (HAIs), which could be caused by pathogens residing on contaminated hospital surfaces. In this longitudinal study, we characterized by NGS the bacterial composition of nasal swabs of preterm newborns, at the time of birth and after admission to the Neonatal Intensive Care Unit (NICU), comparing it with that of the environmental wards at the time of delivery and during the hospitalization. We characterized the resistome on the samples too. The results showed that environmental microorganisms responsible for HAIs, in particular Staphylococcus spp., Streptococcus spp., Escherichia-Shigella spp., and K. pneumoniae, were detected in higher percentages in the noses of the babies after 13 days of hospitalization, in terms of the number of colonized patients, microorganism amount, and relative abundance. The analysis of nasal bacteria resistome evidenced the absence of resistance genes at the time of birth, some of which appeared and increased after the admission in the NICU. These data suggest that hospital surface microbiota might be transported to respiratory mucosae or other profound tissues. Our study highlights the importance of a screening that allows characterizing the microbial profile of the environment to assess the risk of colonization of the newborn.

Abstract
INTRODUCTION Hematopoietic Stem Cell Transplantation (HSCT) is a life-saving procedure for multiple types of hematological cancer, autoimmune diseases, and genetic-linked metabolic diseases in humans. Recipients of HSCT transplant are at high risk of microbial infections that significantly correlate with the presence of graft-versus-host disease (GVHD) and the degree of immunosuppression. Infection in HSCT patients is a leading cause of life-threatening complications and mortality. AREAS COVERED This review covers issues pertinent to infection in the HSCT patient, including bacterial and viral infection; strategies to reduce GVHD; infection patterns; resistance and treatment options; adverse drug reactions to antimicrobials, problems of antimicrobial resistance; perturbation of the microbiome; the role of prebiotics, probiotics, and antimicrobial peptides. We highlight potential strategies to minimize the use of antimicrobials. EXPERT OPINION Measures to control infection and its transmission remain significant HSCT management policy and planning issues. Transplant centers need to consider carefully prophylactic use of antimicrobials for neutropenic patients. The judicious use of appropriate antimicrobials remains a crucial part of the treatment protocol. However, antimicrobials' adverse effects cause microbiome diversity and dysbiosis and have been shown to increase morbidity and mortality.

Abstract
Objective Because of the COVID-19 pandemic there has been a significant increase in the prevalence of nosocomial infections. As a result, we sought to find an effective, efficient and safe way to train healthcare workers on proper hand washing techniques. We used powdered activated carbon (PAC) as a tracer to visually display hand washing defects after the hand washing process. The real-time visual assessment of the efficacy of the hand washing technique aided in the immediate correction of errors, and this definitively improved hand hygiene techniques of the interns. Methods Clinical interns at the emergency department of Shengjing Hospital were included in this study and received training in relation to the six-step hand-washing technique developed by the World Health Organization (WHO). The subjects’ hand-washing defects or faults were traced using PAC and corrected accordingly. Acceptance of the PAC tracing method by the interns, and its safety, were both assessed using a questionnaire survey. Results The results indicated that the back of the hands, fingers, and the wrists were prone to hand-washing defects. The hand-washing defects were significantly reduced after targeted corrections by the trainers. Subjects reported satisfactory acceptance toward the PAC tracing method and the method was relatively safe for subjects. Conclusion The PAC tracing method can visually display hand-washing defects and significantly improve the effectiveness of hand-washing training.

Abstract
Background Hospital-acquired infections can be acquired by a patient or develop among hospital staff, as a more serious problem in low- and middle-income hospital settings. Assessing the level of knowledge, attitude and practice towards hospital-acquired infection prevention among healthcare workers and identifying the associated factors has an unquestionable importance of handling and management of these infections. Thus, in this study, we evaluated the knowledge, attitude and practice towards HAIs prevention and associated factors in healthcare workers at the University of Gondar Comprehensive Specialized Hospital, North West Ethiopia. Methods Hospital-based cross-sectional study was conducted among healthcare workers towards HAIs prevention from January to June 2019. Each study participant was selected by simple random sampling. Data were collected using structured self-administered questionnaires. Descriptive analysis was used to present frequency and percentage of the main findings. The association between independent variables and KAP scores on HAI prevention was calculated using Pearson’s Chi square and p-values less than 0.05 were considered as statistically significant. Results A total of 236 participants were included in this study with a 100% response rate; 90% and 57.2% of the participants had good knowledge and positive attitude towards HAI prevention, respectively. Meanwhile, only 36% of the study participants had good practice towards HAI prevention, suggesting less than satisfactory scores in this study. Level of education and work experience were significantly associated with safe-infection prevention attitude and practice (P value <0.005). Conclusion Even though the respondents have good knowledge with a sympathetic attitude about HAI preventions, good knowledge did not translate into prudent practices. Level of education and work experience were the independent risk factors towards HAI prevention of attitude and practice. Provision of continual on-job and off-job trainings together with strict implementation of updated standard operational procedures (SOP) may reduce the identified gap.

Abstract
Despite numerous measures to contain the infection and limit its spread, cases of SARS-CoV-2 infections acquired in hospitals have been reported consistently. In this paper, we will address issues of hospital-acquired COVID-19 in hospitalized patients as well as medico-legal implications. After having conducted a literature search, we will report on papers on hospital-acquired SARS-CoV-2 infections. Ten scientific papers were selected and considered suitable for further analysis. According to several reports, the SARS-CoV-2 hospital-acquired infection rate is 12–15%. Hospital-acquired COVID-19 represents a serious public health issue, which is a problem that could create reluctance of patients to seek hospital treatment for fear of becoming infected. Healthcare personnel should do all that is necessary to address the problem and prevent further spreading, such as rigorous compliance with all procedures for containing the spread. From a medical-legal point of view, multiple aspects must be considered in order to understand whether the infection is a result of “malpractice” or an inevitable condition.

Abstract
BACKGROUND The COVID-19 outbreak has highlighted the role of hospital-acquired infections in spreading epidemics. Adequately cleaning surfaces in patient rooms is an essential part of this fight to reduce the spread. Traditional audits, however, are insufficient. This study assesses surface cleaning practices using ultravoilet (UV) marker technology and the extent to which this technology can help improve cleaning audits and practices. METHODS One hundred and forty-four audits (1,235 surfaces) were retrieved. UV-marker cleaning audits conducted at a major teaching hospital in 2018 after implementing a new cleaning protocol. In addition, semi-structured interviews were conducted with cleaning staff and supervisors. RESULTS On average, 63% of surfaces were appropriately cleaned. Toilet handles (80%) and toilet seats underside (83%) scored highest while main room sink fixtures (54%), light switch (55%), and bedrails (56%) scored lowest. Training, staffing and time constraints may play a role in low cleaning rates. DISCUSSION The high-touch patient surfaces in the bedroom remain neglected and a potential source of infections. UV marker audits provided an objective measure of cleaning practices that managers and staff were unaware of. CONCLUSIONS UV-markers audits can play a key role in revealing deficiencies in cleaning practices and help in raising awareness of these deficiencies and improving cleaning practices.

Abstract
BACKGROUND In the United States, nosocomial infections are estimated to cause 72,000 annual deaths. The stethoscope, commonly used, is rarely reported as a potential vector. Our study aims to describe stethoscope contamination and the effect of self-reported cleaning practices among health care providers in a community hospital setting. METHODS Stethoscopes were collected at random times from health care providers and cultured per standard techniques. Providers answered a structured questionnaire related to their cleaning practices. Differences in bacterial growth rates and the impact of profession, cleaning frequency, and prior sanitization were evaluated. RESULTS Of 104 cultured stethoscopes, 44% were from residents and medical students, from which 76% had bacterial growth, and 56% were from attendings, nurses, and respiratory therapists who had 91.4% growth (95% = confidence interval 0.62-0.86 and 0.81-0.96, respectively). Overall, 86.5% of providers claimed disinfection frequency compliant with Center for Disease Control and Prevention guidelines but there were no statistical differences between self-reported cleaning frequency or methods, and the presence of bacteria. CONCLUSIONS Most stethoscopes are contaminated with bacteria, the presence of which was not affected by reported cleaning strategies.

Abstract
INTRODUCTION Using mobile phones for communication in emergency departments is a common practice; however, several studies have demonstrated that they may act as vectors for bacteria and viruses. This study evaluated the effectiveness of plastic wrapping in decreasing bacterial contamination on mobile phone surfaces. METHOD We used culture dishes and a luminometer to detect bacterial colonies and contamination on the phone surfaces. RESULT Our experiment showed that bacterial colonies exist on mobile phones before and after work. We found that wiping with 75% alcohol sanitizers effectively reduces the number of colonies on either a mobile phone or a temporary plastic covering. In addition, we found that bacterial colonies do not contaminate or adhere to plastic wrap any easier than to mobile phones. CONCLUSION These results demonstrated the effectiveness of plastic wrap for protecting mobile phone surfaces against bacterial colonization. In addition, applying a layer of plastic wrap protects the phone from potential damage due to the alcohol.
