Abstract
The nail unit is the most commonly affected area in hand infections, which can be primary infection or superinfection complicating other nail or skin disorders. Trauma, mechanical or chemical, is usually the trigger enabling infiltration of infectious organisms. Artificial nails and nail polish are also a possible cause of bacterial infection, harboring microorganisms. In severe acute bacterial infection, surgical intervention is often needed to prevent morbidity and disability. Abscess should always be drained, but viral infection such as herpetic whitlow, may mimic an abscess and, in contrast, requires non-operative treatment; to prevent sequelae. A more conservative approach is also generally advisable in less severe bacterial infection, other viral infections and in subacute or chronic nail infection. The present review deals with acute, subacute and chronic bacterial and viral infections of the nail unit, with a focus on diagnostic and treatment options. LEVEL OF EVIDENCE: III, systematic review of level III studies.

Abstract
BACKGROUND Availability of alcohol-based hand rub (ABHR) dispensers at positions adapted to the work flow of healthcare workers (HCWs) is decisive in order to carry out indication-based hand rubbing. Although requirements and guidelines regarding the positioning of ABHR dispensers are in place, scientific evidence is often lacking. METHODS In order to analyse the impact of the location and number of ABHR dispensers on hand hygiene performance, additional dispensers were systematically placed in patient rooms in a surgical 38-bed ward at Marburg University Hospital, Germany to complement the existing dispenser locations. ABHR use was monitored continuously before and after complementation using the NosoEx hand hygiene monitoring system. The ward had 53 dispensers before the intervention and 82 dispensers after the intervention. RESULTS The addition of dispensers increased ABHR consumption across the entire ward. Before the intervention, mean consumption was 20.6 mL/patient-day, whereas mean consumption after the intervention was 25.3 mL/patient-day. Depending on the combination of dispenser locations, consumption increased through targeted supplementation in patient rooms. The presence of two or three dispensers per patient room resulted in significantly greater ABHR consumption compared with one dispenser per patient room. The preferred location combinations were entrance-front bed-back bed and entrance-foot end. CONCLUSION ABHR consumption can be increased significantly by optimizing the position and number of dispensers. The outstanding factors are visibility and integrability of dispenser use into the work flow; in particular, a dispenser should be positioned in the entrance area. Recommendations should be optimized with regard to the required number and location of dispensers in patient rooms.

Abstract
BACKGROUND Foodborne pathogen transmission during food preparation is a common occurrence, and cross-contamination can be a contributing factor. Behaviors that lead to cross-contamination during meal preparation have not been well characterized. The study objective was to determine how hands and food handling behaviors (with a focus on handwashing and touch-based events) affect the risk of cross-contamination of kitchen surfaces and foods during meal preparation. METHODS Data from a prior study in which participants were observed preparing turkey burgers inoculated with bacteriophage MS2 and a salad provided the data for analysis. Cross-contamination was assessed using environmental sampling data. Behavioral coding was performed for handwashing and touch-based behaviors. Cross-contamination risk was defined as the likelihood (number of contaminated surfaces) and degree (contaminant concentration) of MS2 on surfaces. Statistical analyses were performed in R, SPSS, and SigmaPlot. RESULTS The significantly reduced risk of cross-contamination (P.ß<.ß.0001) was observed for participants who attempted handwashing or completed more handwashing steps. Scrubbing hands for 5.ßseconds, on average, reduced the risk of cross-contamination (P.ß<.ß.05). Cross-contamination regression models created using the most significant predictor variables showed that increased handwashing attempts, completion of more handwashing steps, and average scrub times>5.ßseconds all decreased the risk of cross-contamination (P.ß<.ß.05). CONCLUSIONS This analysis can be used in future risk assessment modeling and for informing education and outreach to reduce pathogen transmission during food preparation.

Effectiveness of implementing of an infection control link nurse program to improve compliance with standard precautions and hand hygiene among nurses: a quasi-experimental study. BMC MEDICAL EDUCATION 2023; 23:265. [PMID: 37076871 PMCID: PMC10116755 DOI: 10.1186/s12909-023-04208-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Accepted: 03/29/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND Standard precautions (SPs) including hand hygiene are considered fundamental protective measures to manage health care-associated infections (HCAIs) and to reduce occupational health hazards. The purpose of this research was to examine the effectiveness of an infection control link nurse (ICLN) program on compliance with SPs and hand hygiene among nurses. METHODS A quasi-experimental study with a pretest-post-test design was conducted with participating of 154 clinical nurses who worked in different wards of a tertiary referral teaching hospital in Iran. The intervention group (n = 77) had 16 infection control link nurses nominated. The control group (n = 77) received only the standard multimodal approach used in the hospital. Pre- and post-test assessment of compliance with standard precautions and hand hygiene compliance was performed via the Compliance with Standard Precautions Scale (CSPS) and the World Health Organization observational hand hygiene form. Two independent sample t-tests were used to examine differences between Compliance with Standard Precautions and hand hygiene Compliance among nurses in intervention and control group. Multiple linear regression analysis was used to assess the effect size. RESULTS After developing and implementing the infection control link nurse program, no statistically significant improvement was found in the Compliance with Standard Precautions (β = 5.18; 95% CI= -0.3-10.65, p = 0.064). An improvement in hand hygiene compliance was observed among nurses in the intervention group that improved statistically significant from 18.80% before the program to 37.32% 6 months after the program (β = 20.82; 95% CI 16.40-25.25, p < 0.001). CONCLUSIONS Given the continuing level of interest that exists in improving health care workers' hand hygiene practices, the findings of this study provide significant practical implications for hospitals seeking to improve compliance with hand hygiene among nurses, showing the effectiveness of using infection control link nurse program. Further research is needed to assess effectiveness of using infection control link nurse program to improve compliance with standard precautions.

Abstract
INTRODUCTION The study aimed to improve the qualified rate of hand hygiene and reduce the incidence of peritonitis in peritoneal dialysis (PD) patients. METHODS A hand hygiene questionnaire was distributed to patients during home visits and outpatient visits in 2015 and 2020. Hand-washing practices were evaluated by collecting cultures from the hands of patients after hand washing, evaluating their household environment, and recording the antimicrobial resistance of pathogenic bacteria. RESULTS Compared to patients in 2015, patients in 2020 had fewer errors in hand washing (p < 0.05), but the rate of qualification after hand washing was lower (p < 0.01). Furthermore, patients who used hand disinfectants after washing had a higher qualified rate. Coagulase-negative staphylococcus (CNS) was the most common isolated bacteria. From 2015 to 2020, the annual incidence of CNS PD peritonitis did not decrease, while the proportion of methicillin-resistant CNS decreased. CONCLUSION The use of hand disinfectants after standard hand washing may help reduce the incidence of peritonitis in PD patients.

Abstract
Background Manual dexterity is vital in nursing. Nurses need to carry out applications requiring manual dexterity in the quickest and most accurate way. However, gloves are also necessary during such applications as a precaution against infections. Therefore, manual dexterity and the effect of gloves on manual dexterity are essential subjects to be investigated in the nursing field. Aims This study aims to determine the effect of using gloves on the manual dexterity of nursing students. Materials and Method The sample of the semi-experimental study consisted of 80 nursing students. The data were collected using a questionnaire and Purdue Pegboard Test. Results The participants were 22.03 ± 1.35 years of age on average; 61.2% of them were 22 years of age or above, 50% were female, 50% were male, 50% were in the third grade, 50% were in the fourth, 80% were high school graduates, and 97.5% did not work in any job. As a result, 47.5% reported that gloves impacted their manual dexterity, 52.5% reported only a partial effect, 12.5% indicated that gloves increased their manual dexterity, 66.3% stated that it reduced their manual dexterity, and 21.2% reported no change. The right-hand and assembly scores were found to be significantly higher in the tests performed with bare hands than in the tests performed with gloves (P < 0.05). Conclusions Using latex gloves impacts the dominant-hand dexterity and assembly dexterity. Therefore, designing more ergonomic gloves, increasing nurses' habit of working with gloves already in school, and supporting the improvement of their manual dexterity with gloves are recommended.

Abstract
The spread of coronavirus disease 2019 (COVID-19) has promoted the use of hand sanitizers among the general population as recommended by health authorities. Alcohols, which are used in many hand sanitizers, have been shown to promotes the formation of biofilms by certain bacteria and to increase bacterial resistance to disinfection. We investigated the effect of continued use of alcohol-based gel hand sanitizer on biofilm formation by the Staphylococcus epidermidis resident strain isolated from the hands of health science students. Hand microbes were counted before and after handwashing, and the ability to produce biofilms was investigated. We found that 179 (84.8%) strains of S. epidermidis isolated from hands had the ability to form biofilm (biofilm-positive strains) in an alcohol-free culture medium. Furthermore, the presence of alcohol in the culture medium induced biofilm formation in 13 (40.6%) of the biofilm-negative strains and increased biofilm production in 111 (76.6%) strains, which were classified as low-grade biofilm-producing. Based on our findings, there is no clear evidence that the continued use of alcohol-based gels results in the selection of strains with the capacity to form biofilms. However, other disinfectant formulations that are more commonly used in clinical settings, such as alcohol-based hand-rub solutions, should be tested for their long-term effects.

Abstract
Nosocomial infections remain an important issue for patient safety concerns. Since hospital infections are mainly connected with healthcare professionals' routines, an increase in hand hygiene effectiveness through compliance with the "bare below the elbow" (BBE) concept could reduce the number of nosocomial infections. Therefore, this study aims to evaluate hand hygiene and to investigate healthcare professionals' compliance with the BBE concept. We performed our study on a group of 7544 hospital professionals involved in patient care. During the national preventive action, questionnaires, demographic data, and hand hygiene preparations were recorded. Hand disinfection was verified by COUCOU BOX, containing a UV camera. We noted that 3932 (52.1%) persons complied with the BBE rules. Nurses and non-medical personnel were significantly more often classified as BBE rather than non-BBE (2025; 53.3% vs. 1776; 46.7%, respectively, p = 0.001 and 1220; 53.7% vs. 1057; 46.3%, p = 0.006). Different proportions were demonstrated for the groups of physicians-non-BBE (783; 53.3%) compared to BBE (687; 46.7%) (p = 0.041). Healthcare workers from the BBE group statistically more often disinfected their hands correctly (2875/3932; 73.1%) compared to the non-BBE group (2004/3612; 55.5%) (p < 0.0001). This study demonstrates the positive impact of compliance with the BBE concept on effective hand disinfection and patient safety. Therefore, education and infection-prevention actions should be popularized to improve the BBE policy's effectiveness as well.

Abstract
Background Meticillin-resistant Staphylococcus pseudintermedius (MRSP) infections in companion animals are increasing and are difficult to treat. Environmental contamination with MRSP in small animal primary care hospitals may pose an exposure risk to animal patients. Methods This longitudinal study assessed the genotypic relationships of MRSP isolated from 39 environmental samples collected from six private small animal primary care hospitals, in the north-eastern United States, between August 2018 and April 2019. Results Of the 39 bacterial isolates, 18 unique pulsotypes were identified based on pulsed-field gel electrophoresis, including six clusters of two or more indistinguishable isolates. Single pulsotypes were frequently detected from multiple hand-contact and animal-contact surfaces within a hospital during a single sampling event, but detection of a single pulsotype within the same hospital on subsequent visits was infrequent. However, one pulsotype was recovered from three separate hospitals, which suggests that either MRSP transmission between hospitals may have occurred via people, animals, or fomites or that there was a dominant community strain. Conclusions Single strains of MRSP were isolated from various hand-contact and animal-contact surfaces within hospitals, indicating the important role of humans, animals and the environment in MRSP transmission. Additionally, the detection of a single strain between hospitals and over time suggests that either MRSP transmission between hospitals may have occurred via people, animals or fomites or that there was a dominant community strain.

Abstract
Purpose of Review This review highlights the importance of the anesthesia team in minimizing perioperative infection risks and prevention of surgical site infection. Due to the immense financial and patient care burden that results from perioperative infection, a foundational knowledge in preventive measures is essential. Recent Findings Perioperative infection control, the role of the anesthesia team in reducing infection risk, and more specifically the outsized importance of hand hygiene in this space have become increasingly apparent. Maintenance of workspace cleanliness along with hand hygiene forms the cornerstone of preventing microbial transmission. Unfortunately, improvements around perioperative infection control are lacking. Summary The importance of the anesthesia team in maintaining proper hand hygiene, a clean work environment, and appropriate patient conditions to minimize risk of perioperative infection cannot be overstated. Poor clinical outcomes, economic burden, and external pressure from payers highlight the need for anesthesia providers to have an up-to-date knowledge of best practices in this area. In this article, we will review the current recommendations for hand hygiene practices and perioperative infection prevention.

Abstract
Major medical advances in antibiotics for infectious diseases have dramatically improved the quality of life and greatly increased life expectancy. Nevertheless, the widespread and inappropriate exploitation of antibacterial agents has resulted in the emergence of multi-drug-resistant bacteria (MDR). Consequently, the study of new drugs for the treatment of diseases associated with multi-drug-resistant bacteria and the development of new treatments are urgently needed. Inspiringly, due to the advantages of a wide antimicrobial spectrum, fast sterilization, low resistance, and little damage to host tissues and normal flora, antibacterial photodynamic therapy (APDT), which is based on the interaction between light and a nontoxic photosensitizer (PS) concentrated at the lesion site to generate reactive oxygen species (ROS), has become one of the most promising antibacterial strategies. Recently, a burgeoning APDT based on a variety of upconversion nanoparticles (UCNPs) such as PS and near-infrared (NIR) light has been fully integrated in antibacterial applications and achieved excellent performances. Meanwhile, conjugated nanoparticles have been frequently reported in UCNP design, including surface-modified PS conjugates, antibiotic-PS conjugates, and dual or multiple antibacterial modal PS conjugates. This article provides an overview of the state-of-the-art design and bactericidal effects of UCNPs and their based APDTs. The first part discusses the design and mechanisms for UCNPs currently implemented in biomedicine. The second part focuses on the applications and antimicrobial effects of diverse APDT based on UCNPs in antibacterial-related infectious diseases.

Abstract
In our newborn intensive care unit (NICU), we practise family participatory care, where the unit staff encourage parents and attendants of sick newborns to partner with them and be involved in care for their babies. There remains a concern that this practice may increase the risk of nosocomial infections being carried into the unit by parent-attendants. Staff observed that handwashing behaviours were suboptimal and inconsistent among parent-attendants. With facilitation from an improvement coach, we formed a quality improvement team of NICU staff to improve hand hygiene practices among attendants. From a baseline estimate of around 20% of attendants adhering to hand hygiene standards, the team planned to reach a target of 80% over 8 weeks by introducing a series of changes. At the end of 9 weeks, 80% of attendants were following standard hand hygiene practices.

Abstract
BACKGROUND This review, commissioned by the World Health Organization (WHO), examined the effectiveness of the WHO 6-step hand hygiene (HH) technique in reducing microbial load on hands and covering hand surfaces, and compared its effectiveness to other techniques. METHODS Medline, CINAHL, ProQuest, Web of Science, Mednar, and Google Scholar were searched for primary studies, published in English (1978-February 2021), evaluating the microbiological effectiveness or hand surface coverage of HH techniques in healthcare workers. Reviewers independently performed quality assessment using Cochrane tools. The protocol for the narrative review was registered (PROSPERO 2021: CRD42021236138). RESULTS Nine studies were included. Evidence demonstrated that the WHO technique reduced microbial load on hands. One study found the WHO technique more effective than the 3-step technique (P = .02), while another found no difference between these 2 techniques (P = .08). An adapted 3-step technique was more effective than the WHO technique in laboratory settings (P = .021), but not in clinical practice (P = .629). One study demonstrated that an adapted 6-step technique was more effective than the WHO technique (P = .001). Evidence was heterogeneous in application time, product, and volume. All studies were high risk of bias. CONCLUSIONS Eight studies found that the WHO 6-step technique reduced microbial load on healthcare workers' hands; but the studies were heterogeneous and further research is required to identify the most effective, yet feasible technique.

Abstract
Hand hygiene is the most effective way to prevent nosocomial infections. Nevertheless, the hands of healthcare professionals are still the primary route of transmission of pathogens responsible for such infections. The aim of this study was to evaluate hand disinfection techniques and investigate the risk factors that may explain the improper hand disinfection techniques among healthcare workers. We selected 7544 hospital workers directly involved in patient care. We recorded data based on the questionnaires, demographic data, and the preparation of hands for disinfection, including risk factors. Correct hand disinfection was verified by COUCOU BOX, with a UV camera. Proper hand disinfection was demonstrated among 4879 (64.7%) subjects, while 2665 (35.3%) subjects disinfected their hands incorrectly. In most places of work, nurses properly disinfected their hands more often than the physicians, particularly in general departments (62.1% vs. 69.2%; p = 0.0019). We observed that long nails and artificial/polished nails were more often observed in the group of nurses than in the group of physicians (7.3% vs. 4.7%, respectively; p = 0.0006 and 19.3% vs. 10.1%; p = 0.0000), while an inverse relationship was found in relation to watches (24.0% vs. 12.0%; p = 0.0000) and long sleeves (24.4% vs. 8.1%; p = 0.0000). Incorrect and less effective hand hygiene among some groups of hospital workers is still present. Therefore, the continuation of education actions concerned with hand hygiene among healthcare workers is needed.

Abstract
BACKGROUND Hand hygiene (HH) is the single most important method to prevent infections. We aim at improving HH compliance by visitors to a pediatric oncology unit. METHODS A performance improvement project implemented several Plan-Do-Study-Act cycles in July-November 2018. At baseline, a wall-mounted alcohol-based hand sanitizer dispenser was available at the unit entrance. Cycle 1 (visual cue), cycle 2 (visual cue plus verbal symptom screen), and cycle 3 (visual cue, symptom screen, plus HH verbal instructions) were tested. Patient care associates (PCA) positioned at the entrance implemented the cycles and recorded data about visitor's estimated age, day and time of observations, and covert HH compliance monitoring. Participating PCAs were surveyed regarding process feasibility. RESULTS Of 1230 (97%) analyzed observations; 204 (17%) were baseline, 293 (24%) in cycle 1, 374 (30%) in cycle 2, and 359 (29%) in cycle 3. The visitors' HH compliance significantly increased to 16.0%, 22.5%, and 48.5% in cycles 1, 2, and 3, respectively, from a baseline of 4.9% (P < .001). Visitors were more likely to perform HH when directly instructed (cycle 3) compared to baseline (adjusted OR = 19.77, 95% CI, 10.30-42.09, P < .001). Although the surveyed PCAs agreed the process is easy and fast, they reported few barriers. CONCLUSIONS Direct verbal instructions for HH were the most effective in improving visitors' HH compliance.

Translating a theory-based positive deviance approach into an applied tool: Mitigating barriers among health professionals (HPs) regarding infection prevention and control (IPC) guidelines. PLoS One 2022; 17:e0269124. [PMID: 35657940 PMCID: PMC9165831 DOI: 10.1371/journal.pone.0269124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Accepted: 05/13/2022] [Indexed: 11/18/2022] Open
Abstract
Background
Although a wide range of intervention programs and methods have been implemented to increase health professionals’ (HPs) adherence with infection prevention and control (IPC) guidelines and decrease the incidence of healthcare associated infections (HAIs), a significant discrepancy remains between the guidelines and their implementation in practice.
Objectives
This study proposes an applied tool based on the integrated theoretical framework of the positive deviance (PD) approach for developing more effective interventions to mitigate this discrepancy.
Methods
A qualitative study guided by the PD approach based on data from two sources: (1) in-depth archival analysis of systematic review articles, and (2) integration and synthesis of findings based on an extensive empirical study we conducted, involving 250 HPs (nurses, physicians, support staff and cleaning staff) from three governmental hospitals in Israel, over 35 months (January 2017 to November 2020).
Results
The barriers faced by HPs were classified into four main categories: (1) individual-motivational, (2) social-cultural, (3) organizational, and (4) work environment and resource-centered. For each barrier, we constructed a set of questions based on the PD approach. For each question, we adapted and applied methodological tools (e.g., in-depth interviews, focus groups, social network maps, video clips and simulations) to help solve the problem.
Conclusion
Translating a theory-based approach into an applied tool that offers step-by-step actions can help researchers and practitioners adopt and implement the approach within intervention programs to mitigate barriers.

Abstract
BACKGROUND Photodynamic therapy (PDT) is an effective method to inactivate microorganisms based on reactive oxygen species (ROS) generated by photosensitizer and light at certain wavelength. Exposure to sub-lethal dose of PDT (sPDT) could activate the regulatory systems in the surviving bacteria in response to oxidative stress. This study aimed to evaluate the effect of sPDT on efflux pump and biofilm formation in Staphylococcus aureus (S. aureus), which are two important virulence related factors. METHODS Different light irradiation time and toluidine blue O (TBO) concentrations were tested to select a sPDT in methicillin-susceptible and methicillin-resistant S. aureus (MSSA and MRSA). Efflux function was evaluated with EtBr efflux experiment. Biofilm formation was evaluated by crystal violet staining. Gene expressions of norA, norB, sepA, mepA and mdeA following sPDT were analyzed with real-time PCR. RESULTS Sub-lethal PDT was set at 40 J/cm2 associated with 0.5 μM TBO. Efflux function was significantly inhibited in both strains. The average expression levels of mdeA and mepA in MSSA and MRSA were increased by (3.09, 1.77, 1.57) and (3,44, 1.59, 6.29) fold change respectively, norB and sepA were decreased by (3.77, 6.14) and (3.02, 3.47) fold change respectively. Expression level of norA was decreased by 5.44-fold change in MSSA but increased by 2.80-fold change in MRSA. Biofilm formation in both strains was impeded. CONCLUSIONS TBO-mediated sPDT could inhibit efflux pump function, alter efflux pump encoding gene expression levels and retard biofilm formation in MSSA and MRSA. Therefore, sPDT is proposed as a potential adjuvant therapy for infections.

Abstract
BACKGROUND The effectiveness of hand rubbing with alcohol-based handrub (ABHR) is impacted by several factors. To investigate these, World Health Organization (WHO) commissioned a systematic review. AIM To evaluate the impact of ABHR volume, application time, rubbing friction and hand size on microbiological load reduction, hand surface coverage or drying time. METHODS Medline, CINAHL, Web of Science and ScienceDirect databases were searched for healthcare or laboratory-based primary studies, published in English, (1980- February 2021), investigating the impact of ABHR volume, application time, rubbing friction or hand size on bacterial load reduction, hand coverage or drying time. Two reviewers independently performed data extraction and quality assessment. The results are presented narratively. FINDINGS Twenty studies were included in the review. Categories included: ABHR volume, application time and rubbing friction. Sub-categories: bacterial load reduction, hand size, drying time or hand surface coverage. All used experimental or quasi-experimental designs. Findings showed as ABHR volume increased, bacterial load reduced, and drying times increased. Furthermore, one study showed that the application of sprayed ABHR without hand rubbing resulted in significantly lower bacterial load reduction than poured or sprayed ABHR with hand rubbing (- 0.70; 95%CI: - 1.13 to - 0.28). Evidence was heterogeneous in application time, volume, technique, and product. All studies were assessed as high risk of bias. CONCLUSIONS There is insufficient evidence to change WHO recommendation of a palmful of ABHR in a cupped hand applied for 20-30 s or manufacturer-recommended volume applied for about 20 s (Centers for Disease Control and Prevention). Future hand hygiene research should standardise volume, application time, and consider hand size.

Indirect effects of Covid-19 on water quality. WATER-ENERGY NEXUS 2022; 5:29-38.

Abstract
The provision of safe water and functioning waste management play key roles in preventing and combatting disease outbreaks such as the Covid-19 pandemic. Good water quality is needed for effective hygiene measures like washing hands as well as for lowering pathogen transmission. Almost all over the world, especially in developing countries, water is vulnerable and at high risk and surging insecurity with time. Effective water management, sanitation, and hygiene help to protect lives during the global COVID-19 pandemic. While sanitation and hygiene also disturb the quality and increase water consumption per capita to 40% comparatively and wastewater production in many developing countries. This rapid increase in water consumption puts direct pressure on water reservoirs and inadequate management of wastewater is also a serious threat to waterways, nowadays. Similarly, the quality of water bodies is significantly affected by the COVID-19 pandemic, but the risk of transmission of COVID-19 through sewerage systems is recorded as low. Hence, the current review paper aims to highlight the main concerns directly linked with the frequent usage of detergents/soaps and alcohol-based hand sanitizers on water quality and the post-pandemic handwashing habits to overcome the COVID-19 spread also threatening the water reserve reservoirs via water high consumption along with more wastewater production with less water reuse efficiency and collectively the pressure on drinking water facilities. This review also focuses on the indirect influence of COVID-19 on water quality through technical interventions among COVID-19, water pollution; soaps/detergents, and hand sanitizer and the complete water management plan for water security and safety from policymakers to end users after the viral revolution briefly.

Supplementing hand washing with proper use of alcoholic hand rub in a special neonatal care unit in a large academic public health institute at Jabalpur, Madhya Pradesh, India. BMJ Open Qual 2021; 10:bmjoq-2020-001131. [PMID: 34759034 PMCID: PMC8587682 DOI: 10.1136/bmjoq-2020-001131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Accepted: 10/25/2021] [Indexed: 11/29/2022] Open
Abstract
Objective The purpose was to increase use of alcoholic hand rub (AHR) in specialised newborn care unit (SNCU) to improve hand hygiene in order to reduce neonatal sepsis and mortality at Netaji Subhash Chandra Bose Medical College and Hospital, Jabalpur. Design A prospective interventional and observational study. Methodology We formed a quality improvement (QI) team in our SNCU consisting of doctors, nurses, auxiliary staff and parents (a floating member) to improve proper use of AHR. To identify the barriers to the problem, we used fishbone analysis tool. The barriers which were not allowing the health providers to use AHR properly identified were amount of AHR in millilitres to be used per day per baby, how much and when the amount of AHR to be indented from the main store and what is the proper site to place the bottle. We used plan–do–study–act cycles to test and adapt solutions to these problems. Within 5–6 weeks of starting our project, AHR use increased from 44 mL to 92 mL per baby per day and this is sustained around 100 mL per baby per day for over 2 years now. Results Significant decrease in neonatal mortality was observed (reduced from median of 41.0 between August 2016 and April 2018 to 24.0 between May 2018 and December 2019). The neonates discharged alive improved from 41.2 to 52.3 as a median percentage value. The percentage of babies who were referred out and went Left Against Medical Advice (LAMA) deceased too. Conclusion Multiple factors can lead to neonatal deaths, but the important factors are always contextual to facilities. QI methodology provides health workers with the skills to identify the major factors contributing to mortality and develop strategies to deal with them. Improving processes of care can lead to improved hand hygiene and saves lives.

Nudging hand hygiene compliance: a large-scale field experiment on hospital visitors. J Hosp Infect 2021; 118:63-69. [PMID: 34560166 DOI: 10.1016/j.jhin.2021.09.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 09/03/2021] [Accepted: 09/15/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND Hospital-care-associated infections (HCAIs) represent the most frequent adverse event during care delivery, affecting hundreds of millions of patients around the world. Implementing and ensuring conformity to standard precautions, particularly best hand hygiene practices, is regarded as one of the most important and cheapest strategies for preventing HCAIs. However, despite consistent efforts at increasing conformity to standard hand hygiene practices at hospitals, research has repeatedly documented low conformity levels amongst staff, patients and visitors alike. AIM The behavioural sciences have documented the potential of adjusting seemingly irrelevant contextual features in order to 'nudge' people to conform to desirable behaviours such as hand hygiene compliance (HHC). In this field experiment we investigate the effect on HHC amongst visitors upon entry of a hospital by varying such features. METHODS Over 50 days, we observed the HHC of a total of 46,435 hospital visitors upon their entry to the hospital in a field experimental design covering eight variations over the salience, placement and assertion of the hand sanitizer in the foyer, including the presence of the yearly national HHC campaign and a follow up during the COVID-19 pandemic. FINDINGS Our experiment found that varying seemingly irrelevant features increased HHC from a baseline of 0.4%-19.7% (47.6% during COVID-19). The experiment also found that the national HHC-campaign had no direct statistically significant effect on HHC. CONCLUSION Varying seemingly irrelevant contextual features provides an effective, generic, cheap and easy to scale approach to increasing HHC relative to sanitizing one's hands at hospitals.

Abstract
In this paper, the photodynamic effect of a ternary nanocomposite (TiO2-Ag/graphene) on Escherichia coli bacteria and two human cell lines: A375 (melanoma) and HaCaT (keratinocyte) after exposure to different wavelength domains (blue, green or red-Light Emitting Diode, LED) was analyzed. The results obtained through bioassays were correlated with the morphological, structural and spectral data obtained through FT-IR, XPS and UV-Vis spectroscopy, powder X-Ray diffractometry (XRD) and STEM/EDX techniques, leading to conclusions that showed different photodynamic activation mechanisms and effects on bacteria and human cells, depending on the wavelength. The nanocomposite proved a therapeutic potential for blue light-activated antibacterial treatment and revealed a keratinocyte cytotoxic effect under blue and green LEDs. The red light-nanocomposite duo gave a metabolic boost to normal keratinocytes and induced stasis to melanoma cells. The light and nanocomposite combination could be a potential therapy for bacterial keratosis or for skin tumors.

Abstract
Introduction Healthcare-associated infections (HCAIs) are an important contributor to patient morbidity and mortality. Healthcare workers (HCWs) hands are the chief mode of transmission of HCAIs. The emergency centre (EC) is frequently the first point of contact for patients within the health care system. The aim of this study is to determine compliance with hygiene practices among healthcare workers at a tertiary hospital EC. Methods Hygiene practices of staff were observed over a six-week period. Data pertaining to compliance rates with hand cleansing and other hygiene practices was collected. Consent was obtained retrospectively to avoid influencing participant behaviour. Results From a total of 477 potential hygiene opportunities, compliance with hand hygiene was only 34.4% (n = 164). Hand cleansing with an alcohol-based hand rub was observed in 87 (26.7%) of the 326 (68.3%) opportunities where it was indicated, while handwashing with soap and water was observed in 35 (23.2%) of the 151 opportunities where this was indicated. Compliance to each of the six steps of handwashing ranged between 62.2% and 83.5%, with there being a gradual deterioration in compliance from step one through to step six. Compliance with ‘bare below the elbows’ was observed in 242 (50.7%) opportunities while disposable surgical gloves were worn on 85 (44.7%) of the 190 opportunities where this was indicated. Conclusion Compliance with hygiene practices among EC HCWs is suboptimal. Various strategies including ongoing systematic training and regular audits may improve overall hygiene practices among EC staff.

Abstract
PURPOSE The purpose of this quality improvement project was to evaluate transparent vascular access dressings and the use of a liquid gum mastic adhesive on improving dressing integrity over peripheral intravenous (PIV) insertion sites without increasing medical adhesive-related skin injuries (MARSIs) such as tears. PARTICIPANTS AND SETTING A multidisciplinary team consisting of specialists in infection prevention, vascular access, nursing professional development, materials management, and WOC nurses met to review current audit data and available products to trial on 2 intermediate care units in our 2 hospitals in Indiana with a combined average daily unit census of 35 patients. APPROACH Four dressing protocols-including our existing dressing with education, and an updated dressing with education, and the updated and new dressing, both with education and the addition of a gum mastic adhesive agent-were sequentially implemented by nurses on the units, each over a 2-week period. The goal was for 80% of the dressings to remain with all 4 corners fully intact without reinforcement at day 7, or sooner if PIV was discontinued before day 7. Data were reported as frequencies for intact dressings and skin complications. OUTCOMES Education combined with the original dressing and the updated dressing did not achieve the goal of 80% fully intact dressings in the samples evaluated. The addition of the adhesive agent to the updated and new dressings with education exceeded the 80% goal. In addition, there were zero exposed PIV insertion sites and no documented MARSI in any of the 4 protocols. IMPLICATIONS FOR PRACTICE We continued to collect postproject data of 30,049 vascular access sites including central line catheters and observed the same effectiveness of incorporating a gum mastic adhesive on dressing integrity. This practice change has now become standard of care in our institution.

Abstract
Clostridioides difficile, a spore-forming bacterium, is a nosocomial infectious pathogen which can be found in animals as well. Although various antibiotics and disinfectants were developed, C. difficile infection (CDI) remains a serious health problem. C. difficile spores have complex structures and dormant characteristics that contribute to their resistance to harsh environments, successful transmission and recurrence. C. difficile spores can germinate quickly after being exposed to bile acid and co-germinant in a suitable environment. The vegetative cells produce endospores, and the mature spores are released from the hosts for dissemination of the pathogen. Therefore, concurrent elimination of C. difficile vegetative cells and inhibition of spore germination is essential for effective control of CDI. This review focused on the molecular pathogenesis of CDI and new trends in targeting both spores and vegetative cells of this pathogen, as well as the potential contribution of nanotechnologies for the effective management of CDI.

Abstract
Objective: To develop evidence-based recommendations on best practices for delivery of clinical preventive services by chiropractors and to offer practical resources to empower provider applications in practice. Design: Clinical practice guideline based on evidence-based recommendations of a panel of practitioners and experts on clinical preventive services. Methods: Synthesizing the results of a literature search for relevant clinical practice guidelines and systematic reviews, a multidisciplinary steering committee with training and experience in health promotion, clinical prevention, and/or evidence-based chiropractic practice drafted a set of recommendations. A Delphi panel of experienced practitioners and faculty, primarily but not exclusively chiropractors, rated the recommendations by using the formal consensus methodology established by the RAND Corporation/University of California. Results: The Delphi consensus process was conducted during January-February 2021. The 65-member Delphi panel reached a high level of consensus on appropriate application of clinical preventive services for screening and health promotion counseling within the chiropractic scope of practice. Interprofessional collaboration for the successful delivery of clinical preventive services was emphasized. Recommendations were made on primary, secondary, tertiary, and quaternary prevention of musculoskeletal pain. Conclusions: Application of this guideline in chiropractic practice may facilitate consistent and appropriate use of screening and preventive services and foster interprofessional collaboration to promote clinical preventive services and contribute to improved public health.

Abstract
Background Accessibility to alcohol-based handrub (ABHR) dispenser is crucial to improve compliance to hand hygiene (HH), being offered as wall-mounted dispensers (ABHR-Ds), and/or pocket bottles. Nevertheless, information on the distribution and density of ABHR-Ds and their impact on HH have hardly been studied. Institutions such as the World Health Organisation or the Centers for Disease Control and Prevention do not provide guidance. The Robert-Koch-Institute (RKI) from Germany recommends an overall density of > 0.5 dispensers per patient bed. We aimed to investigate current conditions in hospitals to develop a standard on the minimal number of ABHR-D. Methods Between 07 and 09/2019, we applied a questionnaire to 178 hospitals participating in the Swissnoso National Surveillance Network to evaluate number and location of ABHR-Ds per bed in acute care hospitals, and compared the data with consumption and compliance with HH. Results 110 of the 178 (62%) hospitals provided data representing approximately 20,000 hospital beds. 83% hospitals provided information on both the total number of ABHR-Ds and patient beds, with a mean of 2.4 ABHR-Ds per bed (range, 0.4–22.1). While most hospitals (84%) had dispensers located at the room entrance, 47% reported also locations near or at the bed. Additionally, pocket-sized dispensers (100 mL) are available in 97% of hospitals. Conclusions Swiss hospitals provide 2.4 dispensers per bed, much more than governmental recommendation. The first study on the number of ABHR-Ds in hospitals may help to define a minimal standard for national and international recommendations Supplementary Information The online version contains supplementary material available at 10.1186/s13756-021-00949-0.

Abstract
Objectives The aim of this study was to describe the characteristics of hand-to-environmental contact (HEC) and to identify the factors influencing HEC behavior in Korean adults’ indoor daily life. Methods Thirty participants were enrolled from January 14 to February 12, 2018 after providing informed consent for being videotaped. Data were collected by recording their indoor daily lives for 2 hours, resulting in 4,732 HEC cases. To ensure the accuracy and reliability of the HEC readings, 3 training sessions were conducted for the videotape readers. Rereading and verifying randomly selected data ensured the validity of intra- and inter-reader readings. Results The most frequent contact items were phones, papers, computer accessories, and furniture surfaces. The contact density (frequency-duration/min) was highest for category II (items occasionally shared by others, 56.8), followed in descending order by category I (items for individual use, 35.9), and category III (public use items, 3.4). Significant differences in contact density were found according to participants’ demographic characteristics. Conclusion As mobile phones were the most frequent contact item, regular and strict mobile phone cleansing or disinfection strategies are needed, in addition to preventative measures taken for category II and III items. Avoiding sharing personal items with others, refraining from unnecessary HEC, and maintaining strict hand hygiene are recommended.

Motivating healthcare professionals (nurses, nurse assistants, physicians) to integrate new practices for preventing healthcare-associated infections into the care continuum: turning Positive Deviance into positive norms. BMC Infect Dis 2021; 21:495. [PMID: 34049512 PMCID: PMC8161960 DOI: 10.1186/s12879-021-06215-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2020] [Accepted: 05/20/2021] [Indexed: 11/18/2022] Open
Abstract
Background The literature examining healthcare-associated infections (HAI) points to two main problems in conforming to infection prevention and control (IPC) guidelines among healthcare professionals (HP). One is the discrepancy between HPs’ behavioral intentions and their implementation in practice. The other refers to how HPs maintain these practices after the intervention stage ends. The method proposed in this study seeks to address both these issues by using the Positive Peviance (PD) approach to focus on the dissemination stage of interventions. The study seeks to offer a method for disseminating 27 PD practices to 135 HPs, among them nurses, nurse assistants and physicians, so as to help them maintain IPC guidelines, offer feedback on the dissemination process and examine the impact of the dissemination stage on changes in their behavior. Methods The theoretical model underlying this qualitative research was the Recognition-Primed dDecision (RPD) model, which we implemented in the field of healthcare-associated infections (HAIs). Moreover, we used the Discovery & Action Dialogue (DAD) and Think Aloud (TA) techniques to describe the methodological development of simulations for HPs. Feedback from the HP demonstrators underwent content analysis, while descriptive statistics were used to characterize behavioral changes. Results HPs’ information processing regarding infection prevention shifts from peripheral/automatic processing to intuition and analytical/central processing, turning PD practices into positive norms. The HPs personally experienced finding a solution and made repeated corrections until they overcame the barriers. Most of the HPs (69.4%) reported that the practices were fully implemented, together with additional practices. Conclusions Implementation of the dissemination stage indicates that in order for HPs to integrate and assimilate practices that are not in the official guidelines, merely observing simulations is not sufficient. Rather, each staff member must personally carry out the procedures.

Abstract
OBJECTIVES Hand-to-face contact (HFC) is the major route for the self-inoculation of pathogens. This study aimed to describe the characteristics of HFC behaviors among Korean adults during indoor activities. METHODS Thirty participants were enrolled in the study, and 2 hours of videotaped data were collected from each participant. Contact data were recorded by examining the frequency and duration of HFC on the videos. Three training sessions were conducted for 2 readers to ensure the accuracy and reliability of videotape reading. Re-reading and verification of selected video data were performed to confirm intrapersonal and interpersonal validity. Contact exposure (CE) was determined by multiplying the contact frequency (CF) by the contact duration (CD) to quantify the intensity of contact during the observation time (2 hours). RESULTS A total of 3,007 HFCs (1,305 mucous membrane contacts and 1,702 non-mucous membrane contacts) were observed for 60 person-hours. The median CF (person/2 hr) of the mucous membranes (eye; 4.0, nose; 15.5, mouth; 16.5) was 39.5/person and the median total CD was 177.0 sec/person. The median CE (frequency-duration/sec/person) was 5,795.0 (mouth: 1,356.0, nose: 600.0, eye: 57.5). CONCLUSIONS This study showed that the mouth and nose were the most frequent exposure sites for HFC. Avoiding habitual HFC, awareness of self-inoculation by HFC, and vigorous hand hygiene should be strengthened to prevent the spread of infections.

Development and application of tools to cost the delivery of environmental health services in healthcare facilities: a financial analysis in urban Malawi. BMC Health Serv Res 2021; 21:329. [PMID: 33849531 PMCID: PMC8042714 DOI: 10.1186/s12913-021-06325-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Accepted: 03/28/2021] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Environmental health services (EHS) in healthcare facilities (HCFs) are critical for providing a safe, functional healthcare environment, but little is known about their costs. Poor understanding of costs impedes progress towards universal access of EHS in HCFs. We developed frameworks of essential expenses required to provide EHS and conducted an ex-post financial analysis of EHS in a network of medical research and training facilities in Lilongwe, Malawi, serving an estimated 42,000 patients annually through seven outpatient buildings. METHODS We estimated the cost of providing the following EHS: water, sanitation, hygiene, personal protective equipment use at the point of care, waste management, cleaning, laundry, and vector control. We developed frameworks of essential outputs and inputs for each EHS through review of international guidelines and standards, which we used to identify expenses required for EHS delivery and evaluate the completeness of costs data in our case study. For costing, we use a mixed-methods approach, applying qualitative interviews to understand facility context and review of electronic records to determine costs. We calculated initial costs to establish EHS and annual operations and maintenance. RESULTS Available records contained little information on the upfront, capital costs associated with establishing EHS. Annual operations and maintenance totaled USD 220,427 for all EHS across all facilities (USD 5.21 per patient encounter), although costs of many essential inputs were missing from records. Annual operations and maintenance costs were highest for cleaning (USD 69,372) and waste management (USD 46,752). DISCUSSION Missing expenses suggests that documented costs are substantial underestimates. Costs to establish services were missing predominantly because purchases pre-dated electronic records. Annual operations and maintenance costs were incomplete primarily because administrative records did not record sufficient detail to disaggregate and attribute expenses. CONCLUSIONS Electronic health information systems have potential to support efficient data collection. However, we found that existing records systems were decentralized and poorly suited to identify EHS costs. Our research suggests a need to better code and disaggregate EHS expenses to properly leverage records for costing. Frameworks developed in this study are a potential tool to develop more accurate estimates of the cost of providing EHS in HCFs.

CLABSI reduction using evidence based interventions and nurse empowerment: a quality improvement initiative from a tertiary care NICU in Pakistan. Arch Dis Child 2021; 106:394-400. [PMID: 32253277 DOI: 10.1136/archdischild-2019-318779] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2019] [Revised: 03/02/2020] [Accepted: 03/13/2020] [Indexed: 12/29/2022]
Abstract
OBJECTIVE Central line associated bloodstream infection (CLABSI) is an important cause of morbidity and mortality in the neonatal intensive care unit (NICU). We designed a CLABSI Prevention Package (CPP) to decrease NICU CLABSI rates, using evidence-proven interventions. DESIGN This was a quality improvement (QI) project. Data collection was divided into three phases (pre-implementation, implementation and post implementation). SQUIRE2.0 guidelines were used to design, implement and report this QI initiative. SETTING A tertiary care level 3 NICU at the Aga Khan University Hospital (AKUH), Karachi, Pakistan. PATIENTS All patients admitted to the AKUH NICU from 1 January 2016 to 31 March 2018 who had a central line in place during their NICU admission. INTERVENTIONS CPP used evidence-based interventions focusing on hand hygiene, aseptic central line insertion techniques and central line care, prevention of fungal infections and nurse empowerment. MAIN OUTCOME MEASURES CLABSI rates pre and post intervention were recorded. Secondary outcomes were risk factors for CLABSI, device (central line) utilisation ratio, CLABSI related mortality and micro-organism profile. RESULTS CLABSI rates decreased from 17.1/1000 device days to 5.0/1000 device days (relative risk (RR)=0.36, CI=0.17-0.74). Device (central line) utilisation ratio declined from 0.30 to 0.25. Out of 613 patients enrolled in our study, 139 (22.7%) died. Mortality was higher in CLABSI group (n=20, 44%) as compared with non CLABSI group (n=119, 21.1%) (p<0.001). Gestational age of <27 weeks was an independent risk factor for CLABSI (RR=4.45, CI=1.10-18.25, p=0.03). A total of 158 pathogens were isolated among which 68 were associated with CLABSI. Gram-negative bacteria 31 (47.7%) were the most common cause of CLABSI. Ninety-seven (61%) micro-organisms were multi-drug resistant. CONCLUSIONS CPP was effective in decreasing NICU CLABSI rates and can be used as a model to decrease NICU CLABSI rates in low or middle-income countries.

Abstract
Hand hygiene can be considered a strategic key useful in the containment of infections such as COVID-19 both at home and in communities because it can dramatically reduce the widespread outbreak of infections. In case of the unavailability of soap and water, "instant" hand sanitizers are recommended because their application can be considered easy, versatile, quick and often less aggressive for the skin. For these reasons, alcoholic and alcohol-free hand rub gels can be considered the best performing formulations on the market. Together with disinfectants and antiseptic agents, hydrogels play a fundamental role in obtaining stable formulations and are easy to disperse, with a pleasant skin feel and an overall good performance. Several compounds commonly used in the pharmaceutical, cosmetic and food industry are available for this purpose, in particular, cellulose derivatives and synthetic polymers derivatives. Each of them is available in several grades, presenting different thickening behavior, rheological properties and compatibility with other ingredients, alcohols in particular. For all these reasons, it is important to explore hydrogel properties and behaviors in different contexts (i.e., hydroalcoholic and aqueous media) in order to develop new and performing hand rub gels, always taking into account the different international legal frameworks regarding disinfectant and sanitizing formulations.

Abstract
Increasing threats from both pathogenic infections and antibiotic resistance highlight the pressing demand for nonantibiotic agents and alternative therapies. Herein, we report several new phenothiazinium-based derivatives, which could be readily synthesized via fragment-based assembly, which exhibited remarkable bactericidal activities both in vitro and in vivo. Importantly, in contrast to numerous clinically and preclinically used antibacterial photosensitizers, these compounds were able to eliminate various types of microorganisms, including Gram-(+) Staphylococcus aureus (S. aureus), Gram-(-) Escherichia coli, multidrug-resistant S. aureus, and their associated biofilms, at low drug and light dosages (e.g., 0.21 ng/mL in vitro and 1.63 ng/cm2 in vivo to eradicate S. aureus at 30 J/cm2). This study thus unveils the potential of these novel phenothiaziniums as potent antimicrobial agents for highly efficient photodynamic antibacterial chemotherapy.

Abstract
Background Regarding the protection of community and health professionals suffering from a COVID-19 outbreak, currently different alcohol-based hand sanitizers have been distributed. Even though for effective protection effective alcohol-based hand sanitizers are mandatory. Their efficacy was not evaluated. This is the reason why this research was designed to assess the antimicrobial efficacy of hand sanitizers that have been sold in southern parts of Ethiopia. Methods Six test organisms (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Salmonella typhimurium and Shigella boydii) were selected from different clinical specimens. Then seven locally made products of alcohol-based hand sanitizers (MTU, Folium Fine, Epharm, Harego, Taflen and Sheba) were purchased and the disc diffusion, minimum inhibition concentration and minimum bactericidal concentration test were done against selected test organisms. Quality control measures throughout the whole process of the laboratory work were implemented and descriptive parameters were analyzed. Results The zones of inhibition of the hand sanitizers at their claim concentration were ranged from noninhibition zone (Folium) to 27mm (Sheba). The minimum inhibitory concentration against all selected test organisms was observed at 45%, 55%, 65% and Taflen on undiluted form. The growth of test organisms was decreased across increasing the concentration gradient of different hand sanitizers. MTU except against E. coli, Fine, Hargo, Ephra and Sheba hand sanitizers were showed growth below 60% concentrations for all test micro-organisms. But a Folium product against all selected test micro-organisms and MTU product against E. coli were not bactericidal. Conclusion Fine, Hargo, Ephra, Sheba and Taflen sanitizers were the products that were effective in inhibiting the growth of all the selected test organisms, and they were having effective bactericidal activity in vitro at their claim concentration. But MTU product against E. coli and Folium product against all test microorganisms were not having an effective bactericidal activity. So, regulatory authorities and manufacturers should implement strict quality control measures and regular observations throughout the production to ensure the efficacy of hand sanitizers.

Abstract
Bacterial and viral infections of the nail unit are very common as primary infections, especially bacterial paronychia and warts, but they can also be superinfections complicating other nail disorders. In many nail unit infections, the clinical presentation is nonspecific: in these cases, diagnostic tests are mandatory before treatment, to avoid spread of the infection and drug resistance. The most common forms of bacterial and viral infections that may affect the nail unit are herein described in detail, with diagnostic and treatment options provided.

Abstract
Cardiac implantable electronic devices (CIEDs) are commonly used nowadays. The association between CIED placement and infections is responsible for the high mortality and device explantation rate. Since CIED placement has increased in the past decade, CIED-related complications have risen. In order to reduce the CIED-related complications rate, the prevention of device infection represents the main goal. Over time, many different studies have proven the importance of the measures to prevent CIED-related infections. This review aims to collect the actual recommendations for CIED infection prevention, providing an overview of the main evidence-based strategies.

Abstract
In low- and middle-income countries (LMICs), hand sanitizer may be a convenient alternative to soap and water to increase hand hygiene practices. We explored perceptions, acceptability, and use of hand sanitizer in rural Bangladesh. We enrolled 120 households from three rural villages. Promoters distributed free alcohol-based hand sanitizer, installed handwashing stations (bucket with tap, stand, basin, and bottle for soapy water), and conducted household visits and community meetings. During Phase 1, promoters recommended handwashing with soap or soapy water, or hand sanitizer after defecation, after cleaning a child's anus/feces, and before food preparation. In Phase 2, they recommended separate key times for hand sanitizer: before touching a child ≤ 6 months and after returning home. Three to 4 months after each intervention phase, we conducted a survey, in-depth interviews, and group discussions with child caregivers and male household members. After Phase 1, 82/89 (92%) households reported handwashing with soap after defecation versus 38 (43%) reported hand sanitizer use. Participants thought soap and water removed dirt from their hands, whereas hand sanitizer killed germs. In Phase 2, 76/87 (87%) reported using hand sanitizer after returning home and 71/87 (82%) before touching a child ≤ 6 months. Qualitative study participants reported that Phase 2-recommended times for hand sanitizer use were acceptable, but handwashing with soap was preferred over hand sanitizer when there was uncertainty over choosing between the two. Hand sanitizer use was liked by household members and has potential for use in LMICs, including during the coronavirus pandemic.

Petrosino F, Mukherjee D, Coppola G, Gaudio MT, Curcio S, Calabro V, Marra F, Bhattacharya P, Pal U, Khélifi N, Chakraborty S. Transmission of SARS-Cov-2 and other enveloped viruses to the environment through protective gear: a brief review. EURO-MEDITERRANEAN JOURNAL FOR ENVIRONMENTAL INTEGRATION 2021; 6:48. [PMID: 33842691 PMCID: PMC8024444 DOI: 10.1007/s41207-021-00251-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 02/22/2021] [Indexed: 05/17/2023]
Abstract
Over the past two decades, several deadly viral epidemics have emerged, which have placed humanity in danger. Previous investigations have suggested that viral diseases can spread through contaminants or contaminated surfaces. The transmission of viruses via polluted surfaces relies upon their capacity to maintain their infectivity while they are in the environment. Here, a range of materials that are widely used to manufacture personal protective equipment (PPE) are summarized, as these offer effective disinfection solutions and are the environmental variables that influence virus survival. Infection modes and prevention as well as disinfection and PPE disposal strategies are discussed. A coronavirus-like enveloped virus can live in the environment after being discharged from a host organism until it infects another healthy individual. Transmission of enveloped viruses such as SARS-CoV-2 can occur even without direct contact, although detailed knowledge of airborne routes and other indirect transmission paths is still lacking. Ground transmission of viruses is also possible via wastewater discharges. While enveloped viruses can contaminate potable water and wastewater through human excretions such as feces and droplets, careless PPE disposal can also lead to their transmission into our environment. This paper also highlights the possibility that viruses can be transmitted into the environment from PPE kits used by healthcare and emergency service personnel. A simulation-based approach was developed to understand the transport mechanism for coronavirus and similar enveloped viruses in the environment through porous media, and preliminary results from this model are presented here. Those results indicate that viruses can move through porous soil and eventually contaminate groundwater. This paper therefore underlines the importance of proper PPE disposal by healthcare workers in the Mediterranean region and around the world.

Abstract
The emergence of SARS-CoV-2, the causative agent of COVID-19, highlights the increasing need for new and effective antiviral and antimicrobial agents. The FDA has recently banned several active ingredients used in hand sanitizers, including triclosan and benzethonium chloride. Nitric oxide (NO) is involved in the innate immune response and is a major component of macrophage-mediated attack on foreign viruses and bacteria. The specific aim of this study was to assess the antibacterial effects of 2-(N,N-diethylamino)-diazenolate-2-oxide (DEA-NONOate) against Escherichia coli (E. coli). A bacterial growth assay was compared to an adenosine triphosphate (ATP) activity assay at various time points to assess effects of DEA-NONOate on E. coli growth. A UV/Vis spectrophotometer was used to determine concentration of E. coli by measuring optical density (OD) at 630 nm. A luminescent assay was used to measure ATP activity correlating to viable cells. DEA-NONOate at a concentration of 65 mM was able to inhibit the growth of E. coli with the same efficacy as 1 μg ml-1 concentration of ciprofloxacin. Both the OD and ATP assays demonstrated a 99.9% reduction in E. coli. Both a 1 μg ml-1 concentration of ciprofloxacin and a 65 mM concentration of DEA-NONOate achieved 99.9% inhibition of E. coli, verified using both optical density measurement of bacterial cultures in 96 well plates and a luminescent ATP activity assay. The bactericidal effects of DEA-NONOate against E. coli is proof-of-concept to pursue evaluation of nitric oxide-based formulations as antimicrobial and antiviral agents as hand sanitizers.

Abstract
Numerous studies are published on the benefits of electric hand dryers vs paper towels (PT) for drying hands after washing. Data are conflicting and lacking key variables needed to assess infection risks. We provide a rapid scoping review on hand-drying methods relative to hygiene and health risks. Controlled vocabulary terms and keywords were used to search PubMed (1946-2018) and Embase (1947-2018). Multiple researchers independently screened abstracts for relevance using predetermined criteria and created a quality assessment scoring system for relative study comparisons. Of 293 papers, 23 were included in the final analysis. Five studies did not compare multiple methods; however, 2 generally favoured electric dryers (ED); 7 preferred PT; and 9 had mixed or statistically insignificant results (among these, 3 contained scenarios favourable to ED, 4 had results supporting PT, and the remaining studies had broadly conflicting results). Results were mixed among and within studies and many lacked consistent design or statistical analysis. The breadth of data does not favour one method as being more hygienic. However, some authors extended generalizable recommendations without sufficient scientific evidence. The use of tools in quantitative microbial risk assessment is suggested to evaluate health exposure potentials and risks relative to hand-drying methods. We found no data to support any human health claims associated with hand-drying methods. Inconclusive and conflicting results represent data gaps preventing the advancement of hand-drying policy or practice recommendations.
