RESUMO

In December of 2019, there was an outbreak of a severe acute respiratory syndrome caused by the coronavirus 2 (SARS-CoV-2 or COVID-19) in China. The virus rapidly spread into the whole world causing an unprecedented pandemic and forcing governments to impose a global quarantine, entering an extreme unknown situation. The organizational consequences of quarantine/isolation are absence of organized training and competition, lack of communication among athletes and coaches, inability to move freely, lack of adequate sunlight exposure, and inappropriate training conditions. The reduction of mobility imposed to contain the advance of the SARS-Cov-2 pandemic can negatively affect the physical condition and health of individuals leading to muscle atrophy, progressive loss of muscle strength, and reductions in neuromuscular and mechanical capacities. Resistance training (RT) might be an effective tool to counteract these adverse consequences. RT is considered an essential part of an exercise program due to its numerous health and athletic benefits. However, in the face of the SARS-Cov-2 outbreak, many people might be concerned with safety issues regarding its practice, especially in indoor exercise facilities, such as gyms and fitness centers. These concerns might be associated with RT impact in the immune system, respiratory changes, and contamination due to equipment sharing and agglomeration. In this current opinion article, we provide insights to address these issues to facilitate the return of RT practices under the new logistical and health challenges. We understand that RT can be adapted to allow its performance with measures adopted to control coronavirus outbreak such that the benefits would largely overcome the potential risks. The article provides some practical information to help on its implementation.

RESUMO

This review sought to provide an overview of proposed methods and protocols for processing surgical instruments contaminated with prions. A search of PubMed was conducted to identify studies published between January 1, 2012, and January 2, 2019, with no language restrictions and using varying combinations of the following terms: prions (Medical Subject Heading [MeSH]) OR decontamination (MeSH) OR cleaning OR disinfection OR sterilization. Articles were excluded if they did not involve medical device surfaces or describe the processing protocol. At least two reviewers independently selected articles, extracted data, and assessed data. A total of 627 articles published in peer-reviewed journals were identified. Of the 55 articles assessed for full-text eligibility, eight met the inclusion criteria. Only a few studies investigated protocols and methods for processing prion-contaminated medical devices; therefore, determining the best way to sterilize device surfaces and preserve the integrity of surgical instruments remains challenging. Moreover, the perspective of sterile processing department staff continues to be overlooked when designing studies.

RESUMO

COVID-19 pandemic has strongly and rapidly affected routine lifestyle and consequently, dental business, practice, and education. During the pandemic period, most Governments worldwide made specific regulations or recommendations to close practices, to avoid non-urgent dental therapies and treat only dental emergencies. Some recent surveys1,2 showed how dentists perceived the COVID-19 risk and how they reacted: by modifying their way of working, by reducing aerosol producing procedures, by improving staff and patient's safety with the increased use of personal protective equipment, environmental disinfection and limited access to dental offices, increasing use of remote consulting and triage.

RESUMO

Since 1995, ASET has periodically published updates to recommendations for best practices in infection prevention for Neurodiagnostic technologists. The latest installment was accepted in December 2019 for publication in Volume 60, Issue 1, before we had much knowledge or understanding about the SARS-CoV-2, the virus that causes COVID-19. This Technical Tips article is presented as an addendum to the 2020 update and includes important information about infection prevention measures specific to procedure protocols when working with patients positive or under investigation for a highly infectious disease, and when working with patients in general during the current pandemic. All Neurodiagnostic technologists who have direct patient care are responsible for ensuring the use of best practices to prevent the spread of infection.

RESUMO

Background: Despite endodontic infections being a common problem in the primary dentition, some of the infected primary teeth can remain functional until the exfoliation through endodontic treatment. The primary endodontic treatment goal must be to optimize root canal disinfection and to prevent reinfection. Aim: The aim of this study is to compare the antifungal efficacy of antimicrobial photodynamic therapy, LASER, and 1% clotrimazole as irrigants by reducing the colony-forming units (CFU) of Candida albicans in the infected root canals of primary teeth. Materials and Methods: Pulp therapy was performed on deciduous mandibular second molars of 20 healthy children aged 5-8 years, which were divided into four groups of intracanal disinfection protocols: Group 1 (n = 5) - Sodium Hypochlorite, Group 2 (n = 5) - Photodynamic, Group 3 (n = 5) - Normal saline with LASER, and Group 4 - (n = 5) Antifungal. Disinfection potential was compared by collecting samples one just after access opening and the other after the experimental groups using paper points. The samples were cultured and incubated for 48 h to check change in CFU of the fungi. Results: Data were analyzed statistically using the Shapiro-Wilk's test, Mann-Whitney U-test; Kruskal-Wallis test, and Wilcoxon signed-ranks test. No significant difference (P > 0.05) was found between the different groups. However, complete inhibition of C. albicans CFU was seen with Group 4. Conclusion: One percent Clotrimazole (antifungal) can be utilized as an adjunct in the endodontic irrigation protocol for better success of pulpectomy in children.

RESUMO

In this paper we develop a compartmental epidemic model to study the transmission dynamics of the COVID-19 epidemic outbreak, with Mexico as a practical example. In particular, we evaluate the theoretical impact of plausible control interventions such as home quarantine, social distancing, cautious behavior and other self-imposed measures. We also investigate the impact of environmental cleaning and disinfection, and government-imposed isolation of infected individuals. We use a Bayesian approach and officially published data to estimate some of the model parameters, including the basic reproduction number. Our findings suggest that social distancing and quarantine are the winning strategies to reduce the impact of the outbreak. Environmental cleaning can also be relevant, but its cost and effort required to bring the maximum of the outbreak under control indicate that its cost-efficacy is low.

RESUMO

BACKGROUND: The purpose of this study was to determine the extent of air and surface contamination of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in four health care facilities with hospitalized coronavirus disease 2019 (COVID-19) patients. METHODS: We investigated air and environmental contamination in the rooms of eight COVID-19 patients in four hospitals. Some patients were in negative-pressure rooms, and others were not. None had undergone aerosol-generating procedures. On days 0, 3, 5, and 7 of hospitalization, the surfaces in the rooms and anterooms were swabbed, and air samples were collected 2 m from the patient and from the anterooms. RESULTS: All 52 air samples were negative for SARS-CoV-2 RNA. Widespread surface contamination of SARS-CoV-2 RNA was observed. In total, 89 of 320 (27%) environmental surface samples were positive for SARS-CoV-2 RNA. Surface contamination of SARS-CoV-2 RNA was common in rooms without surface disinfection and in rooms sprayed with disinfectant twice a day. However, SARS-CoV-2 RNA was not detected in a room cleaned with disinfectant wipes on a regular basis. CONCLUSION: Our data suggest that remote (> 2 m) airborne transmission of SARS-CoV-2 from hospitalized COVID-19 patients is uncommon when aerosol-generating procedures have not been performed. Surface contamination was widespread, except in a room routinely cleaned with disinfectant wipes.

RESUMO

BACKGROUND: Endoscopic evaluation plays an indispensable role in medical treatments designed to prevent, diagnose, and cure gastrointestinal disease. Surveillance culture monitoring may be useful in monitoring the outcome of reprocessing. PURPOSE: In this project, microbiologic surveillance cultures were employed to improve the quality of flexible endoscope disinfection. RESOLUTION: This project, implemented from February 1st, 2018 to February 28th, 2019, used several approaches to improve the positive culture rate. We redesigned and implemented the standard operating procedures for endoscope reprocessing, established an in-service training course, provided education materials on reprocessing, and installed a storage cabinet that custom-built to accommodate the endoscope. RESULTS: The positive culture rate was reduced from 5.8% to 0%. CONCLUSIONS: Endoscopy culturing is a useful method to assess the effectiveness of standard reprocessing procedures. The development of guidelines and skill practices should follow current, evidence-based practice and infection prevention principles, and related documents should be organized. We suggest regularly deploying quality-improvement techniques to improve performance and service delivery.

RESUMO

Household spraying is a commonly implemented, yet an under-researched, cholera response intervention where a response team sprays surfaces in cholera patients' houses with chlorine. We conducted mixed-methods evaluations of three household spraying programs in the Democratic Republic of Congo and Haiti, including 18 key informant interviews, 14 household surveys and observations, and 418 surface samples collected before spraying, 30 minutes and 24 hours after spraying. The surfaces consistently most contaminated with Vibrio cholerae were food preparation areas, near the patient's bed and the latrine. Effectiveness varied between programs, with statistically significant reductions in V. cholerae concentrations 30 minutes after spraying in two programs. Surface contamination after 24 hours was variable between households and programs. Program challenges included difficulty locating households, transportation and funding limitations, and reaching households quickly after case presentation (disinfection occurred 2-6 days after reported cholera onset). Program advantages included the concurrent deployment of hygiene promotion activities. Further research is indicated on perception, recontamination, cost-effectiveness, viable but nonculturable V. cholerae, and epidemiological coverage. We recommend that, if spraying is implemented, spraying agents should: disinfect surfaces systematically until wet using 0.2/2.0% chlorine solution, including kitchen spaces, patients' beds, and latrines; arrive at households quickly; and, concurrently deploy hygiene promotion activities.

RESUMO

We explore the opportunities and challenges surrounding the use of disinfection robots to reduce the risk of SARS-CoV-2 transmission in health care and educational settings. Although there is some potential for deploying robots to help with manual cleaning, the evidence base is mixed, and we highlight that there needs to be work to establish and enhance the effectiveness of these robots in inactivating the virus.

RESUMO

Incidents of viral outbreaks have increased at an alarming rate over the past decades. The most recent human coronavirus known as COVID-19 (SARS-CoV-2) has already spread around the world and shown R0 values from 2.2 to 2.68. However, the ratio between mortality and number of infections seems to be lower in this case in comparison to other human coronaviruses (such as severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV)). These outbreaks have tested the limits of healthcare systems and have posed serious questions about management using conventional therapies and diagnostic tools. In this regard, the use of nanotechnology offers new opportunities for the development of novel strategies in terms of prevention, diagnosis and treatment of COVID-19 and other viral infections. In this review, we discuss the use of nanotechnology for COVID-19 virus management by the development of nano-based materials, such as disinfectants, personal protective equipment, diagnostic systems and nanocarrier systems, for treatments and vaccine development, as well as the challenges and drawbacks that need addressing.

RESUMO

The novel coronavirus disease COVID-19 caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has resulted in a substantial change in eye care and clinical practice. There has been conflicting information and weak evidence on the virus's transmission through tears. Yet, virus detection on cornea and conjunctiva surface as a gateway for infection is not well-studied. Moreover, there have been no reported cases of SARS-CoV-2 transmission through tonometry to date. Thus, this uncertainty has urged this review on evidence-based guidelines and recommendations on tonometer use in the COVID-19 era. The aim of this article is to provide ophthalmologists with recommendations for tonometry practice based on current evidence and best practice guidelines.

RESUMO

: Since the beginning of 2020, the world has been confronted by the Covid-19 pandemic. The lock-down aims to limit the circulation of the virus and thus avoid overwhelming healthcare systems. Healthcare workers have had to adapt by postponing consultation and surgical activities. Otolaryngologists are particularly exposed to infection from the upper airway where the virus is highly concentrated. Literature has previously reported other human coronaviruses in the middle ear and mastoid, suggesting a risk of infection to staff during ear surgery where aerosolizing procedures are usually used. The aim of this article is to propose a strategy for planning consultations and surgeries for ear and lateral skull base diseases, in the context of the current active evolution of the pandemic and of the future gradual recovery to normal practice.

RESUMO

Objective: To generate recommendations on the management of radiotherapeutic treatments during the pandemic, adapted to a country with limited health resources. Methods: We did a rapid review of the literature, searching for papers that describe any measures to reduce the risk of COVID-19 infection, as well as management guidelines to reduce the workload, in radiotherapy units. The following conditions were included in the scope of this review: gynecological tumors, breast cancer, gastrointestinal tumors, genitourinary tumors, head and neck tumors, skin cancer, tumors of the central nervous system, and lymphomas. An expert group discussed online the extracted data and drafted the recommendations. Using a modified Delphi method, the consensus was reached among 14 certificated radio-oncologists. The quality of the evidence that supported the recommendations on treatment schedules was assessed. Results: A total of 57 documents were included. Of these, 25 provided strategies to reduce the risk of infection. Recommendations for each condiction were extracted from the remaining documents. The recommendations aim to establish specific parameters where treatments can be omitted, deferred, prioritized, and shortened. Treatment schemes are recommended for each condition, prioritizing hypo-fractionated schemes whenever possible. Conclusions: We propose strategies for the management of radiotherapy services to guarantee the continuity of high-quality treatments despite the health crisis caused by COVID-19.

RESUMO

Chlorine disinfection inactivates pathogens in drinking water, but meanwhile it causes the formation of halogenated disinfection byproducts (DBPs), which may induce adverse health effects. Humans are unavoidably exposed to halogenated DBPs via tap water ingestion. Boiling of tap water has been found to significantly reduce the concentrations of halogenated DBPs. In this study, we found that compared with boiling only, adding ascorbate (vitamin C) or carbonate (baking soda) to tap water and then boiling the water further reduced the level of total organic halogen (a collective parameter for all halogenated DBPs) by up to 36% or 28%, respectively. Adding ascorbate removed the chlorine residual in tap water and thus prevented the formation of more halogenated DBPs in the boiling process. Adding carbonate elevated pH of tap water and consequently enhanced the hydrolysis (dehalogenation) of halogenated DBPs or led to the formation of more trihalomethanes that might volatilize to air during the boiling process. The comparative developmental toxicity of the DBP mixtures in the water samples was also evaluated. The results showed that adding a tiny amount of sodium ascorbate or carbonate (2.5-5.0 mg/L) to tap water followed by boiling for 5 min reduced the developmental toxicity of tap water to a substantially lower level than boiling only. The addition of sodium ascorbate or carbonate to tap water in household could be realized by preparing them in tiny pills. This study suggests simple and effective methods to reduce the adverse effects of halogenated DBPs on humans through tap water ingestion.

RESUMO

OBJECTIVE: SARS-CoV-2 can reportedly exist on inanimate surfaces for a long duration, but there is limited data available from Italian COVID-19 hospital wards, especially for non-intensive care units hosting patients that do not require mechanical ventilation. Identification of the extent of environmental contamination can help in understanding possible virus transmission routes, limit hospital infections and protect healthcare workers. Thus, we investigated virus contamination on surfaces of the acute COVID-19 ward of an Italian hospital. MATERIALS AND METHODS: Ward surfaces, including four points inside and six points outside the patients' rooms were sampled by swabs, seven hours after routine sanitation. To minimize the risk of underestimation of virus detection, two different sensitive molecular methods were used comparatively, and specific internal controls were added to enhance the efficiency of all the analysis steps. RESULTS: SARS-CoV-2 contamination was detected in only three out of all the collected samples, i.e., on two floors and one-bathroom sink, likely reflecting aerosol and saliva contamination, respectively. The overall level of contamination was low, and the floors exhibited a very low level of SARS-CoV-2 presence, evidenced by only one of the two methods used. CONCLUSIONS: The existence of SARS-CoV-2 on hospital surfaces may be limited, although it was reported to persist for a longer duration on surfaces under controlled laboratory conditions. Thus, effective transmission of SARS-CoV-2 by surfaces/fomites within the hospital ward may be a rare event. However, the results highlight the importance of assessing method sensitivity and including controls when investigating low-level virus contamination so as to avoid the risk of underestimation of virus presence.

RESUMO

An alarming fact was revealed by recent publications concerning disinfectants: chlorhexidine digluconate is ineffective for disinfecting surfaces contaminated by the new coronavirus. This is a finding that requires immediate disclosure since this substance is widely used for the disinfection of hands and forearms of surgeons and auxiliaries and in the antisepsis of patients in minimally invasive procedures commonly performed in hospital environments. The objective of this study is to compare the different disinfectants used for disinfection on several surfaces, in a review of worldwide works. Scientific studies were researched in the BVS (Virtual Health Library), PubMed, Medline, and ANVISA (National Health Surveillance Agency) databases. The following agents were studied: alcohol 62-71%, hydrogen peroxide 0.5%, sodium hypochlorite 0.1%, benzalkonium chloride 0.05-0.2%, povidone-iodine 10%, and chlorhexidine digluconate 0.02%, on metal, aluminum, wood, paper, glass, plastic, PVC, silicone, latex (gloves), disposable gowns, ceramic, and Teflon surfaces. Studies have shown that chlorhexidine digluconate is ineffective for inactivating some coronavirus subtypes, suggesting that it is also ineffective to the new coronavirus.
