ABSTRACT

This article provides a comprehensive overview of the wound healing process, emphasising the critical role of surgical staples in primary intention healing. It outlines the four distinct phases of wound healing including haemostasis, inflammation, proliferation, and maturation - and discusses the mechanisms by which surgical staples enhance this natural biological process. Special focus is given to the aseptic non-touch technique (ANTT), which is crucial in preventing infections during the staple removal procedure. The article further explores the procedural steps involved in the removal of surgical staples and highlights the holistic aspects of patient care that need to be considered. This includes strategies for effective pain management, ensuring informed consent, and maintaining a sterile environment. By integrating clinical skills with a thorough understanding of wound care, this article aims to improve nursing practices in surgical settings, promoting better patient outcomes and recovery.

ABSTRACT

OPINION STATEMENT: Malignant fungating wounds (MFW) are severe skin conditions generating tremendous distress in oncological patients with advanced cancer stages because of pain, malodor, exudation, pruritus, inflammation, edema, and bleeding. The classical therapeutic approaches such as surgery, opioids, antimicrobials, and application of different wound dressings are failing in handling pain, odor, and infection control, thus urgently requiring the development of alternative strategies. The aim of this review was to provide an update on the current therapeutic strategies and the perspectives on developing novel alternatives for better malignant wound management. The last decade screened literature evidenced an increasing interest in developing natural treatment alternatives based on beehive, plant extracts, pure vegetal compounds, and bacteriocins. Promising therapeutics can also be envisaged by involving nanotechnology due to either intrinsic biological activities or drug delivery properties of nanomaterials. Despite recent progress in the field of malignant wound care, the literature is still mainly based on in vitro and in vivo studies on small animal models, while the case reports and clinical trials (less than 10 and only one providing public results) remain scarce. Some innovative treatment approaches are used in clinical practice without prior extensive testing in fungating wound patients. Extensive research is urgently needed to fill this knowledge gap and translate the identified promising therapeutic approaches to more advanced testing stages toward creating multidimensional wound care strategies.

ABSTRACT

BACKGROUND: The degree to which religiosity, spirituality, and self-care practices can improve well-being among infection preventionists is not well understood. METHODS: We surveyed infection preventionists from a random sample of United States hospitals in 2021. Multivariable logistic regression models were used to examine the associations between measures of spirituality, religiosity, and self-care and well-being. RESULTS: Our response rate was 47% (415/881). A total of 49% of respondents reported burnout, 17% reported increased feelings of uncaring, and 69% would choose to become an infection preventionist again. Most respondents found importance in spiritual well-being (88%), religious beliefs (82%), and self-care practices (87%). Spiritual well-being was associated with increased odds of choosing to become an infection preventionist again (odds ratio = 2.32, 95% confidence interval = 1.19-4.53, P = .01). DISCUSSION: Our national survey provides evidence that spiritual importance is associated with career satisfaction among infection preventionists. Our findings contribute to a general body of evidence suggesting spiritual importance may translate to higher flourishing and well-being via serving a higher purpose. CONCLUSIONS: Promoting spiritual well-being may positively influence career satisfaction and overall well-being among infection preventionists.

ABSTRACT

Background: Airborne infection control (AIC) is a less focused aspect of tuberculosis (TB) prevention. We describe AIC practices in primary health care centres, awareness and practices of AIC among health care providers (HCPs) and TB patients. We implemented a package of interventions to improve awareness and practices among them and assessed its impact. Methodology: The study used a quasi-experimental study design. A semi-structured checklist was used for health facility assessment and a self-administered questionnaire of HCPs. Pre- and postintervention assessments were made in urban primary health centers (UPHCs), HCPs, and patients. Interventions included sharing facility-specific recommendations, AIC plans and guidelines, HCP training, and patient education. Statistical difference between the two time periods was assessed using the Chi-square test. Results: A total of 23 and 25 UPHCs were included for pre- and postintervention assessments. All 25 centers participated in interventions. Open areas were >20% of ground area in all facilities. No AIC committee was present in any of the facilities at both pre- and postintervention. Of all HCPs, 7% (23/337) versus 65% (202/310) had undergone AIC training. Good awareness improved from 24% (81/337) to 71% (220/310) after intervention (P < 0.001). Appropriate cough hygiene was known to 20% (51/262) versus 58% (152/263) patients at two assessments (P < 0.001). Conclusion: Comprehensive intervention, including supportive supervision of health centers, training of HCPs, and patient education, can improve AIC practices.

ABSTRACT

Recognition of airborne transmission of SARS-CoV-2 and other respiratory viruses is a paradigm shift in the Infection Prevention and Control (IPC) field, contributed to by New Zealand's experience in Managed Isolation Quarantine Facilities (MIQF). Slowness to embrace this shift by the World Health Organization (WHO) and other international bodies highlights the importance of applying the precautionary principle and subjecting established theories to the same level of critical scrutiny as those challenging the status quo. Improving indoor air quality to reduce infection risk and provide other health benefits is a new frontier, requiring much additional work at both grassroots and policy levels. Existing technologies such as masks, air cleaners and opening windows can improve air quality of many environments now. To achieve sustained, comprehensive improvements in air quality that provide meaningful protection, we also need additional actions that do not rely on individual human's behaviour.

ABSTRACT

BACKGROUND: The City of Hope National Medical Center (COH) is the only stand-alone comprehensive cancer center in Los Angeles, a county that was deemed a COVID-19 pandemic epicenter at the height of the 2020 winter surge. The immunocompromised patient population frequently experienced delays in infection control guidelines from local and government bodies due to minimal data available in comparison to the general population. This required COH to make swift, informed decisions for the best interest of the patient population. AIM: Here, we review the comprehensive COVID-19 infection control response conducted at COH within the context of a high-risk patient population, predominately comprised of patients with hematologic malignancies. METHODS AND RESULTS: This infection control response focused on prevention of COVID-19 transmission on campus, COVID-19 testing, and isolation management. These efforts consisted of COVID-19 screening, limitation of personnel on campus, source control, contact tracing, COVID-19 vaccination, establishment of in-house testing and implementation and management of COVID-19 testing. Between January 2020 and September 2021, COH implemented a robust in-house testing program, completed well over 1000 contact traces, ensured COVID-19 vaccinations were distributed to all eligible staff and patients, and established an algorithm for COVID-19 infection resolution, all without compromising the number of hematopoietic stem cell transplants (HCTs) performed, surgical volume, or healthcare-associated standardized infection ratios (SIR). CONCLUSION: Institutional collaboration and attention to infection control was pivotal to minimizing the burden of the COVID-19 pandemic.

ABSTRACT

Com o advento da covid-19, foi declarado estado de emergência de saúde pública e decretadas medidas de isolamento e distanciamento social para conter a propagação da doença. O Conselho Federal de Psicologia, considerando a importância do acolhimento seguro durante a pandemia, publicou a Resolução CFP nº 4/2020, permitindo que serviços psicológicos aconteçam de maneira remota. O presente estudo visa, através do Método da Cartografia, apresentar a construção de um setting on-line para intervenções grupais e os desafios na oferta de acolhimento e atendimento remoto. Foram ofertados grupos terapêuticos, por meio da plataforma Google Meet, para estudantes da Universidade Federal Rural do Rio de Janeiro. Um diário de bordo foi produzido para acompanhar as forças que atravessavam e constituíam o território e a experiência grupal remota. Compreendemos que o território-espaço-grupal-on-line era composto pelo espaço virtual em que nos reuníamos, pelos espaços individuais de cada integrante e pelas forças que os atravessavam. Observamos que nem sempre os participantes dispunham de um lugar privado, mas estiveram presentes no encontro com câmeras e áudios abertos e/ou fechados e/ou através do chat da videochamada. A participação no grupo funcionou como alternativa no momento de distanciamento social, sendo uma possibilidade para o atendimento psicológico em situações de dificuldade de encontros presenciais; entretanto, se mostrou dificultada em diversos momentos, pela falta de equipamentos adequados e instabilidade na internet, fatores que interferiram nas reuniões e impactaram na possibilidade de falar e escutar o que era desejado.(AU)


With the advent of COVID-19, a state of public health was declared, and measures of isolation and social distance to contain the spread of the disease was decreed. The Federal Council of Psychology, considering the importance of safe reception during the pandemic, published CFP Resolution No. 4/2020, allowing psychological services to happen remotely. This study narrates, via the Cartography Method, the experience of inventing an Online Setting for group reception. Therapeutic groups were offered, via Google Meet Platform, to students at the Federal Rural University of Rio de Janeiro. A logbook was produced to accompany the forces that crossed and constituted the territory and the remote group experience. We understand that the territoryspace-group-online was composed by the virtual-space that we gathered, by the individualspaces of each member and by the forces that crossed them. We observed that the participants did not always have a private place, but they were present at the meeting with open and/or closed cameras and audio and/or through the video call chat. Participation in the group worked as an alternative at the time of social distancing, being a possibility for psychological care in situations of difficulty in face-to-face meetings, however, it proved to be difficult at various times, due to the lack of adequate equipment and instability on the internet, factors that interfered in meetings and impacted the possibility of speaking and listening to what was desired.(AU)

ABSTRACT

PURPOSE: Several studies have confirmed increased mortality among patients with both COVID-19 and cancer. It remains important to continue to report observations of morbidity and mortality from COVID-19 in this vulnerable population. The purpose of this study is to describe the hospitalization characteristics and outcomes of patients with both cancer and COVID-19 admitted to our comprehensive cancer center. METHODS: This was a descriptive study of the first COVID-19-related hospitalization among adult patients with cancer admitted to our institution. Descriptive statistics were used to summarize patient demographics, clinical as well as hospitalization characteristics. Overall survival (OS) was estimated using the Kaplan-Meier method. RESULTS: A total of 212 patients were included in our cohort with a mean age of 59 years. Fifty-four percent of patients had history of solid tumor malignancy and 46% had hematologic malignancies. Eighty-five percent of our cohort had active malignancy. The mean length of stay (LOS) for hospitalization was 11.2 days (median LOS of 6 days). Twenty-five percent had severe disease and 10.8% died during their initial hospitalization. Those who had severe disease had worse survival at the end of the observation period. CONCLUSIONS: COVID-19 among cancer patients causes significant morbidity and mortality as well as repeat hospitalizations. Continued study of COVID-19 in this vulnerable population is essential in order to better inform evolving treatment algorithms, public health policies, and infection control protocols, especially for institutions caring for patients with cancer.

ABSTRACT

As a new variant of COVID-19 with varied mutations, Omicron is more transmissible, more rapidly contagious, and has a greater risk of reinfection. Given those facts, a precise manage strategy needs to be formulated and implemented in designated megacities. Here, the precise COVID-19 prevention and control strategy for a designated hospital in Shenzhen, China is summarized, including implementation of a two-wing "On duty/On standby" approach based on busy and calm periods, an identification, classification, and grading system for the occupational exposure risks of medical staff, classification of patient transmission risks, separate admission, and an innovative treatment (nasal irrigation). The strategy has enabled the efficient and orderly integration of resources, it has resulted in zero infections among medical staff even during the peak hours of the pandemic at the hospital (1,930 patients admitted to both wings in a single day), and it has significantly reduced the initial period of no virus detection when patients infected with Omicron received saline nasal irrigation (P < 0.001). This strategy has provided evidence of precise prevention and control in a hospital, infection control, and efficient patient treatment in an era when Omicron is widespread.

ABSTRACT

BACKGROUND: Industrial hygienists (IH) in the oil and gas business instituted an extraordinary number of safety protocols to limit spread of SARS-CoV-2 onto offshore platforms in the Gulf of Mexico. We used genomic surveillance to provide actionable information concerning the efficacy of their efforts. METHODS: Over 6 months, employees at a single company were serology and PCR tested during a 1-5 day predeployment quarantine and when postdeployment symptoms were reported. From each positive test (n = 49), SARS-CoV-2 genomes were sequenced. Phylogenetic analysis was used to investigate the epidemiology of transmissions. RESULTS: Genomic surveillance confirmed 2 viral strains were infecting 18 offshore workers. Genomic data combined with epidemiological data suggested that a change in quarantine protocols contributed to these outbreaks. A pre-deployment outbreak involved a WHO variant of interest (Theta) that had infected 4 international workers. Two additional predeployment clusters of infections were identified. CONCLUSIONS: Our findings support that IH quarantine/testing protocols limited viral transmissions, halted offshore outbreaks, and stopped the spread of a variant of interest. The study demonstrates how genomic data can be used to understand viral transmission dynamics in employee populations and evaluate safety protocols in the offshore oil and gas industry.

ABSTRACT

INTRODUCTION: Coronavirus disease 2019 (COVID-19) has greatly impacted medical care practices. Although the effects on infectious disease treatment and infection control, such as antimicrobial resistance, have been specified, very few reports exist on the specific effects of COVID-19. METHODS: We investigated the effects of COVID-19 on daily medical practices at a tertiary hospital in Japan by comparing the use of hand sanitizers, the detection of bacteria from blood cultures, and the amount dose of antibacterial drugs used for one year before (April 2019 to March 2020, fiscal year 2019.) and after COVID-19 admissions began (April 2020 to March 2021, fiscal year 2020). RESULTS: The use of hand sanitizers increased by 1.4-3 times during the year after COVID-19 admissions began; the incidence of methicillin-susceptible Staphylococcus aureus and all S. aureus detected in blood cultures reduced in all departments. No decrease was observed in the usage of all antibacterial drugs; rather, the usage of all antibacterial drugs tended to increase in all departments. Therefore, no significant change was observed in the detection of drug-resistant bacteria and the trends of antibacterial drug use based on the acceptance of COVID-19 patients. CONCLUSIONS: The prevalence of drug-resistant bacteria and trends of antibacterial drug use remained unchanged despite the increased use of hand sanitizers due to the admission of patients with COVID-19.

ABSTRACT

Brucellae are intracellular sneaky bacteria and they can elude the host's defensive mechanisms, resulting in therapeutic failure. Therefore, the goal of this investigation was to rapid identification of Brucella species collected from animals and humans in Saudi Arabia, as well as to evaluate their resistance to antibiotics. On selective media, 364 animal samples as well as 70 human blood samples were cultured. Serological and biochemical approaches were initially used to identify a total of 25 probable cultured isolates. The proteomics of Brucella species were identified using the MALDI Biotyper (MBT) system, which was subsequently verified using real-time polymerase chain reaction (real-time PCR) and microfluidic electrophoresis assays. Both Brucella melitensis (B. melitensis) and Brucella abortus (B. abortus) were tested for antimicrobial susceptibility using Kirby Bauer method and the E-test. In total, 25 samples were positive for Brucella and included 11 B. melitensis and 14 B. abortus isolates. Twenty-two out of 25 (88%) and 24/25 (96%) of Brucella strains were recognized through the Vitek 2 Compact system. While MBT was magnificently identified 100% of the strains at the species level with a score value more than or equal to 2.00. Trimethoprim-sulfamethoxazole, rifampin, ampicillin-sulbactam, and ampicillin resistance in B. melitensis was 36.36%, 31.82%, 27.27%, and 22.70%, respectively. Rifampin, trimethoprim-sulfamethoxazole, ampicillin, and ampicillin-sulbactam resistance was found in 35.71%, 32.14%, 32.14%, and 28.57% of B. abortus isolates, correspondingly. MBT confirmed by microfluidic electrophoresis is a successful approach for identifying Brucella species at the species level. The resistance of B. melitensis and B. abortus to various antibiotics should be investigated in future studies.

ABSTRACT

During the first hit of SARS-COVID pandemic, an important reorganization of Healthcare Services has been done, and new protocols and pathways to protect frail patients like oncological patients were designed. The second hit of pandemic had stressed these new pathways and suggests to health-workers some improvements for safer management of patents.We reported our experience in organizing the clinical pathway of neoadjuvant therapy candidate patients based on the execution of sentinel lympho-node biopsy and the placement of implantable venous access port in the same access to operating room before neoadjuvant chemotherapy suggesting a possible organizational model. In the period October-December 2020 we have included in this new type of path twelve patients and we have not registered any cases of COVID among the patients included. We think this new path, adopted amid the second hit, will be useful for all Breast Units that are facing the challenge of guaranteeing the highest standards of care in a historical moment where the health emergency occupies the efforts of health workers and the economic resources of health systems.

ABSTRACT

Pseudomonas aeruginosa is a Gram-negative bacterial pathogen that is a common cause of nosocomial infections, particularly pneumonia, infection in immunocompromised hosts, and in those with structural lung disease such as cystic fibrosis. Epidemiological studies have identified increasing trends of antimicrobial resistance, including multi-drug resistant (MDR) isolates in recent years. P. aeruginosa has several virulence mechanisms that increase its ability to cause severe infections, such as secreted toxins, quorum sensing and biofilm formation. Management of P. aeruginosa infections focuses on prevention when possible, obtaining cultures, and prompt initiation of antimicrobial therapy, occasionally with combination therapy depending on the clinical scenario to ensure activity against P. aeruginosa. Newer anti-pseudomonal antibiotics are available and are increasingly being used in the management of MDR P. aeruginosa.

ABSTRACT

Biofilm mediated infections have major clinical impact. Staphylococcus aureus is a pathogen that frequently causes biofilm forming infections, such as those associated with medical devices and persistent wounds. Microorganisms embedded in biofilm are impervious to antibiotics and other antimicrobial agents, thus they are difficult to eliminate. The upsurge of multi-drug resistant strains makes treating such illnesses even more difficult. Therefore, new strategies are required to combat such type of infections. In this work, we have proposed an alternative therapeutic option to eradicate preformed biofilm of vancomycin resistant Staphylococcus aureus (VRSA) and enhanced phagocytosis by neutrophils in fresh human blood using curcumin mediated antimicrobial photodynamic therapy (aPDT).At sub-MIC of curcumin, different anti-biofilm assays and microscopic examinations were performed, followed by 20 J/cm2 of blue laser light irradiation which corresponds to 52 s only. The result showed significant disruption of VRSA biofilm. Moreover, when curcumin-aPDT treated VRSA biofilm was exposed to whole blood from healthy donors, it was nearly completely eradicated. The present study suggests that curcumin-aPDT enhanced phagocytosis may be a useful strategy for inactivating VRSA biofilms adhering to medical implant surfaces.

ABSTRACT

The numerous dermatology clinics have decreased or stopped phototherapy sessions due to the increased risk of getting COVID-19 during the current pandemic. In this context, poorly ventilated phototherapy units (PUs) should be redesigned in order to continue UV-based therapies and to protect our patients from getting COVID-19. Recently, it has been reported that ultraviolet C (UVC)-related dose and virus concentration may play a decisive role in the virucidal activity. Considering air changes per hour and viral inactivation time, 30 min of 30-W UVC radiation is able to inactivate poorly ventilated PUs of 3-4 m length, 5.5-7 m width, and 2.7-3 m height. Upper-air UVC radiation for 30 min between sessions would allow us to have more treatment options for numerous dermatological diseases in novel PUs during the COVID-19 pandemic and possible future pandemics.

ABSTRACT

WHAT IS KNOWN AND OBJECTIVE: The purpose of this study was to investigate the effect of imposing infection control programmes (ICPs) and antimicrobial stewardship (AMS) by monitoring the antimicrobial resistance of Pseudomonas aeruginosa. METHODS: Antimicrobial susceptibility testing was performed in accordance with the Clinical and Laboratory Standards Institute and European Committee on Antimicrobial Susceptibility Testing guidelines. ICPs and AMS were initiated at the Fourth Hospital from 2013 to 2018. RESULTS AND DISCUSSION: A total of 2,886 P. aeruginosa isolates were assessed. The antimicrobial resistance trends of the P. aeruginosa strains improved after the intervention measures. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) P. aeruginosa contributed to 18.5% and 3.5% of the total P. aeruginosa strains, respectively. Colistin was the most effective antibiotic against 97.6% of XDR-P. aeruginosa and 99.41% of MDR-P. aeruginosa. The consumption of alcohol-based hand gel (ABHG) increased from 0.6 L to 10.8 L per 1,000 patient-days (PD) (p = 0.005). The yearly consumption of antibiotics decreased from 45 to 37.5 defined daily doses (DDD) per 1,000 PD(p = 0.04). After 2013, the incidence rate of MDR-P. aeruginosa showed a significant decrease from 22% to 14.1% (p = 0.04), and XDR-P. aeruginosa decreased from 5.8% to 0.9%. The use of ABHG was negatively related to MDR-P. aeruginosa morbidity (r = -0.86; p = 0.021). The consumption of antibiotics was positively related to MDR-P. aeruginosa morbidity (r = 0.86; p = 0.021). WHAT IS NEW AND CONCLUSION: Successful control of MDR-P. aeruginosa resistance was achieved by imposing comprehensive ICPs and AMS.

ABSTRACT

BACKGROUND: Blood/body fluid splash are hazards to health care professionals in their working area. Around twenty bloodborne pathogens are known to be transmitted through these occupational injuries. This problem alters the health status of health care professionals in different ways, including physically, mentally, and psychologically. Even though health professionals especially midwives who are working in delivery rooms are highly affected, little is known about the exposure. So, this study was aimed to assess the prevalence of exposure to blood/body fluid splash and its predictors among midwives working in public health institutions of Addis Ababa city. METHODS: Institution based cross-sectional study was conducted among 438 study participants in public health institutions in Addis Ababa. Data was collected from March 1-20, 2020 by a self-administered questionnaire. The data were entered into Epi data version 3.1 and then exported to SPSS version 24 for analysis. All variables with P<0.25 in the bivariate analysis were included in a final model and statistical significance was declared at P< 0.05. RESULTS: In this study, a total of 424 respondents respond yielding a response rate of 97%. The prevalence of blood and body fluid splashes (BBFs) was 198 (46.7%). Not training on infection prevention, working in two shifts (> 12 hours), not regularly apply universal precautions, job-related stress, an average monthly salary of 5001-8000 were independent predictors of blood and body fluid splashes. CONCLUSION: The study revealed that nearly half of midwives were exposed to BBFS. This highlights the need for key stakeholders such as policymakers and service providers to design appropriate policies to avert this magnitude and making the environment enabling to comply with standard precautions. We recommend that this study may be done by including rural setting institutions and by including other health professionals that are susceptible to BBFS at work. Formal training on infection prevention and safety practice to apply universal precautions will be needed from the concerned bodies to prevent exposures to blood/body fluid splash.

ABSTRACT

The grand challenge to meet the increasing demands for food by a rapidly growing global population requires protecting crops from pests. Natural active substances play a significant role in the sustainable pests and pathogenic microbes management. In recent years, natural products- (NPs), antimicrobial peptides- (AMPs), medicinal plant- and plant essential oils (EOs)-related online resources have greatly facilitated the development of pests and pathogenic microbes control agents in an efficient and economical manner. However, a comprehensive comparison, analysis and summary of these existing web resources are still lacking. Here, we surveyed these databases of NPs, AMPs, medicinal plants and plant EOs with insecticidal, antibacterial, antiviral and antifungal activity, and we compared their functionality, data volume, data sources and applicability. We comprehensively discussed the limitation of these web resources. This study provides a toolbox for bench scientists working in the pesticide, botany, biomedical and pharmaceutical engineering fields. The aim of the review is to hope that these web resources will facilitate the discovery and development of potential active ingredients of pests and pathogenic microbes control agents.

ABSTRACT

BACKGROUND: There are no reports of a large-scale survey on the infection prevention measures against coronavirus disease 2019 (COVID-19) in nephrology facilities. This study investigated the facility-level nephrology practices adopted during the COVID-19 pandemic and their associated challenges. Additionally, the treatment patterns and outcomes of chronic kidney disease (CKD) patients with COVID-19 were reviewed. METHODS: We conducted a nationwide questionnaire survey of 704 educational facilities that were certified by the Japanese Society of Nephrology (JSN) from October 20, 2020 to November 16, 2020. The questionnaire reviewed the facility characteristics, infection prevention measures taken during routine nephrology practice, impact of COVID-19 on nephrology practice, experiences in managing CKD patients with COVID-19, and nosocomial transmission in the nephrology unit. RESULTS: Of the 347 facilities that responded, 95.1% checked outpatients' body temperatures and COVID-19 symptoms at their visits. To reduce face-to-face contact, 80% and 70% of the facilities lengthened the intervals between outpatient visits and introduced online/telephonic consultations, respectively. As a result, more than half of the hospitals experienced a decrease in the numbers of outpatients and inpatients (64% and 50%, respectively). During the study period, 347 facilities managed 479 CKD patients with COVID-19. Oxygen administration and mechanical ventilation were performed for 47.8% and 16.5% of the patients, respectively, with a 9.2% total mortality rate. CONCLUSION: This survey demonstrated that JSN-certified educational nephrology facilities adopted multiple measures to manage the COVID-19 pandemic; however, they faced several challenges. Sharing these experiences could standardize these approaches and prepare us better for the future.
