Smartphone image dataset to distinguish healthy and unhealthy leaves in papaya orchards in Bangladesh.

Papaya, renowned for its nutritional benefits, represents a highly profitable crop. However, it is susceptible to various diseases that can significantly impede fruit productivity and quality. Among these, leaf diseases pose a substantial threat, severely impacting the growth of papaya plants. Consequently, papaya farmers frequently encounter numerous challenges and financial setbacks. To facilitate the easy and efficient identification of papaya leaf diseases, a comprehensive dataset has been assembled. This dataset, comprising approximately 1400 images of diseased, infected, and healthy leaves, aims to enhance the understanding of how these ailments affect papaya plants. The images, meticulously collected from diverse regions and under varying weather conditions, offer detailed insights into the disease patterns specific to papaya leaves. Stringent measures have been taken to ensure the dataset's quality and enhance its utility. The images, captured from multiple angles and boasting high resolution are designed to aid in the development of a highly accurate model. Additionally, RGB mode has been employed to meticulously capture each detail, ensuring a flawless representation of the leaves. The dataset meticulously identifies and categorizes five primary types of leaf diseases: Leaf Curl (inclusive of its initial stage), Papaya Mosaic, Ring Spot, Mites (specifically, those affected by Red Spider Mites), and Mealybug. These diseases are recognized for their detrimental effects on both the leaves and the overall fruit production of the papaya plant. By leveraging this curated dataset, it is possible to train a model for the real-time detection of leaf diseases, significantly aiding in the timely identification of such conditions.

Assessing the impact of preventative measures to limit the spread of Toxoplasma gondii in wild carnivores of Madagascar.

Novel multihost pathogens can threaten endangered wildlife species, as well as humans and domestic animals. The zoonotic protozoan parasite Toxoplasma gondii is transmitted by members of Felidae and can infect a large number of animal species, including humans. This parasite can have significant health consequences for infected intermediate hosts and could further endanger wild carnivore populations of Madagascar. Building on an empirical characterization of the prevalence of the pathogen in local mammals, we used mathematical models of pathogen transmission in a multihost community to compare preventative measures that aim to limit the spread of this parasite in wild carnivores. Specifically, we examined the effect of hypothetical cat vaccination and population control campaigns on reducing the risk of infection by T. gondii in wild Eupleridae. Our model predicted that the prevalence of exposure to T. gondii in cats would be around 72% and that seroprevalence would reach 2% and 43% in rodents and wild carnivores, respectively. Reducing the rodent population in the landscape by half may only decrease the prevalence of T. gondii in carnivores by 10%. Similarly, cat vaccination and reducing the population of definitive hosts had limited impact on the prevalence of T. gondii in wild carnivorans of Madagascar. A significant reduction in prevalence would require extremely high vaccination, low turnover, or both in the cat population. Other potential control methods of T. gondii in endangered Eupleridae include targeted vaccination of wild animals but would require further investigation. Eliminating the threat entirely will be difficult because of the ubiquity of cats and the persistence of the parasite in the environment.

Evaluación del impacto de las medidas preventivas para limitar el contagio de Toxoplasma gondii en los carnívoros silvestres de Madagascar Resumen Los patógenos novedosos con múltiples hospederos pueden amenazar tanto a las especies silvestres como a los humanos y a los animales domésticos. Los miembros de la familia Felidae transmiten el protozoario parásito Toxoplasma gondii, el cual puede infectar a un gran número de especies animales, incluyendo al humano. Este parásito puede generar consecuencias importantes para la salud en los hospederos intermediarios infectados y podría poner más en peligro a las poblaciones de carnívoros silvestres de Madagascar. Usamos modelos matemáticos de la transmisión de patógenos en una comunidad con múltiples hospederos a partir de una caracterización empírica de la prevalencia del patógeno en los mamíferos locales para comparar las medidas preventivas que buscan limitar la transmisión de este parásito en los carnívoros silvestres. En específico, examinamos el efecto de la vacunación hipotética de felinos y las campañas de control poblacional sobre la reducción del riesgo de infección de T. gondii en los Eupleridae silvestres. Nuestro modelo predijo que la prevalencia de la exposición a T. gondii en los felinos sería de un 72% y que la seroprevalencia llegaría al 2% y al 43% en los roedores y carnívoros silvestres, respectivamente. La reducción a la mitad de la población de roedores en el paisaje podría disminuir sólo en un 10% la prevalencia del protozoario en los carnívoros. De forma similar, la vacunación y la reducción de la población de hospederos definitivos tuvieron un impacto limitado sobre la prevalencia de T. gondii en los carnívoros silvestres de Madagascar. Una reducción significativa en la prevalencia requeriría que la población de felinos tuviera una vacunación extremadamente elevada, baja rotación, o ambas. Otros métodos potenciales de control de T. gondii en los Eupleridae incluyen la vacunación de animales silvestres, pero requieren de mayor investigación. La eliminación completa de la amenaza será difícil por la ubicuidad de los felinos y la persistencia del parásito en el ambiente.

The effects of a novel, continuous disinfectant technology on methicillin-resistant Staphylococcus aureus (MRSA), fungi, and aerobic bacteria in 2 separate intensive care units in 2 different states: An experimental design with observed impact on health care associated infections (HAIs).

BACKGROUND: Hospitals are exposed to abundant contamination sources with limited remediation strategies. Without new countermeasures or treatments, the risk of health care-associated infections will remain high. This study explored the impact of advanced photohydrolysis continuous disinfection technology on hospital environmental bioburden. METHODS: Two acute care intensive care units in different locations (ie, Kentucky, Louisiana) during different time periods were sampled every 4 weeks for 4 months for colony-forming units (CFUs) of methicillin-resistant Staphylococcus aureus (MRSA) and fungi on surfaces and floors and fungi and aerobic bacteria in the air. RESULTS: At both sites, surface testing showed greater than 98% reduction in mean fungi and MRSA CFUs. Floor results had reductions by more than 96% for fungi and MRSA at both sites. Aerobic bacterial air and fungal CFUs had reductions up to 72% and 89%, respectively. HAIs declined 70% when postactivation data were compared to preactivation data. DISCUSSION: The continuous nature of advanced photohydrolysis decontamination, its ability to be used in occupied rooms, and its independence of human resources provide an innovative intervention for complex health care environments. CONCLUSIONS: This study is on the pioneering edge of demonstrating that continuous decontamination can reduce surface, floor, and air contamination and thereby reduce the acquisition of HAIs.

Social identification and risk dynamics: How perceptions of (inter)personal and collective risk impact the adoption of COVID-19 preventative behaviors.

Public adoption of preventative behaviors to reduce the transmission of COVID-19 is crucial to managing the pandemic, and so it is vital to determine what factors influence the uptake of those behaviors. Previous studies have identified COVID-19 risk perceptions as a key factor, but this work has typically been limited both in assuming that risk means risk to the personal self, and in being reliant on self-reported data. Drawing on the social identity approach, we conducted two online studies in which we investigated the effects of two different types of risk on preventative measure taking: risk to the personal self and risk to the collective self (i.e., members of a group with which one identifies). Both studies involved behavioral measures using innovative interactive tasks. In Study 1 (n = 199; data collected 27 May 2021), we investigated the effects of (inter)personal and collective risk on physical distancing. In Study 2 (n = 553; data collected 20 September 2021), we investigated the effects of (inter)personal and collective risk on the speed at which tests are booked as COVID-19 symptoms develop. In both studies, we find that perceptions of collective risk, but not perceptions of (inter)personal risk, influence the extent to which preventative measures are adopted. We discuss the implications both conceptually (as they relate to both the conceptualization of risk and social identity processes) and also practically (in terms of the implications for public health communications).

¿Qué hemos aprendido de las encuestas de la AEC, AECP y del Observatorio de Infección en Cirugía? Cumplimiento de las medidas de prevención de infección postoperatoria y comparación con las recomendaciones de la AEC / What have we learned from the surveys of the AEC, AECP and the Observatory of Infection in Surgery? Compliance with postoperative infection prevention measures and comparison with the AEC recommendations

Antes de planificar estrategias de mejora, es crucial conocer el grado de implementación de las medidas preventivas de infección postoperatoria. Se presentan los resultados agregados de 3encuestas realizadas por el Observatorio de Infección en Cirugía a miembros de 11 asociaciones de cirugía y de enfermería quirúrgica. Las preguntas fueron dirigidas a determinar el conocimiento de la evidencia científica, las creencias personales y el uso real de las principales medidas. De 2.295 encuestados, el 45,1% no recibe información de la tasa de infección de su unidad. Se observó un conocimiento insuficiente de algunas de las principales recomendaciones de prevención y unas tasas de utilización, en ocasiones, inquietante. Se indagó sobre las estrategias preferidas para mejorar el cumplimiento de las pautas preventivas y su grado de implementación. Se confirmó la brecha existente entre la evidencia científica y la práctica clínica en la prevención de infecciones en diferentes especialidades quirúrgicas (AU)

Before planning improvement strategies, it is crucial to know the degree of implementation of preventative measures for postoperative infection. The aggregated results of 3surveys carried out by the Observatory of Infection in Surgery to members of 11 associations of surgeons and perioperative nurses are presented. The questions were aimed to determine the knowledge of the scientific evidence, personal beliefs and the actual use of the main measures. Of 2295 respondents, 45.1% did not receive feedback on the infection rate of their unit. Insufficient knowledge of some of the main prevention recommendations and some disturbing rates of use were observed. The preferred strategies to improve compliance with preventive guidelines and their degree of implementation were investigated. A gap between scientific evidence and clinical practice in the prevention of infection in different surgical specialties was confirmed (AU)

Impact of SARS-CoV-2 Virus (COVID-19) Preventative Measures on Communication: A Scoping Review.

Introduction: Face coverings and distancing as preventative measures against the spread of the Coronavirus disease 2019 may impact communication in several ways that may disproportionately affect people with hearing loss. A scoping review was conducted to examine existing literature on the impact of preventative measures on communication and to characterize the clinical implications. Method: A systematic search of three electronic databases (Scopus, PubMed, CINAHL) was conducted yielding 2,158 articles. After removing duplicates and screening to determine inclusion eligibility, key data were extracted from the 50 included articles. Findings are reported following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Extension for Scoping Reviews, including the PRISMA-ScR checklist. Results: Studies fell into three categories: Studies addressing the impacts of personal protective equipment (PPE) and/or distancing on communication in healthcare contexts (n = 20); studies examining the impact of preventative measures on communication in everyday life (n = 13), and studies measuring the impact of face coverings on speech using acoustic and/or behavioral measures (n = 29). The review revealed that masks disrupt verbal and non-verbal communication, as well as emotional and social wellbeing and they impact people with hearing loss more than those without. These findings are presumably because opaque masks attenuate sound at frequencies above 1 kHz, and conceal the mouth and lips making lipreading impossible, and limit visibility of facial expressions. While surgical masks cause relatively little sound attenuation, transparent masks and face shields are highly attenuating. However, they are preferred by people with hearing loss because they give access to visual cues. Conclusion: Face coverings and social distancing has detrimental effects that extend well beyond verbal and non-verbal communication, by affecting wellbeing and quality of life. As these measures will likely be part of everyday life for the foreseeable future, we propose that it is necessary to support effective communication, especially in healthcare settings and for people with hearing loss.

Psychological impact and implementation of preventative measures in hemodialysis centers during the COVID-19 pandemic: a provincial questionnaire survey in China.

OBJECTIVES: This study investigated the psychological status of patients and staff, and the implementation of preventative measures in hemodialysis centers in Guangdong province, China, during the 2019 novel coronavirus disease (COVID-19) pandemic. METHODS: An electronic questionnaire survey was carried out anonymously between March 28 and April 3, 2020. All of the 516 hemodialysis centers registered in Guangdong province were invited to participate in the survey. The questionnaires were designed to investigate the psychological status of hemodialysis patients and general staff members (doctors, nurses, technicians, and other staff), and to address the implementation of preventative measures for administrators (directors or head nurses) of the hemodialysis centers. RESULTS: A total of 1782 patients, 3400 staff, and 420 administrators voluntarily participated in this survey. Patients living in rural areas reported a higher incidence of severe anxiety compared to those living in other areas (in rural areas, towns, and cities, the incidence rate was 17.0%, 9.0%, and 8.9%, respectively, P < 0.001). Medical staff were less likely to worry about being infected than non-medical staff (13.1% vs 30.3%, respectively, P < 0.001). With respect to the implementation of preventative measures, hemodialysis centers in general hospitals outperformed stand-alone blood purification centers, while tertiary hospitals outperformed hospitals of other levels. However, restrictions regarding the admission of non-resident patients were lower in tertiary hospitals than in other hospitals. In this situation, only one patient imported from Hubei province was diagnosed with COVID-19. CONCLUSIONS: COVID-19 did not significantly affect the psychological status of most patients and medical staff members. Due to the implementation of comprehensive preventative measures, there were no cluster outbreaks of COVID-19 in hemodialysis centers. This provincial-level survey may provide referential guidance for other countries and regions that are experiencing a similar pandemic.

Oral Antibiotic Prophylaxis Lowers Surgical Site Infection in Elective Colorectal Surgery: Results of a Pragmatic Cohort Study in Catalonia.

BACKGROUND: The role of oral antibiotic prophylaxis (OAP) and mechanical bowel preparation (MBP) in the prevention of surgical site infection (SSI) after colorectal surgery is still controversial. The aim of this study was to analyze the effect of a bundle including both measures in a National Infection Surveillance Network in Catalonia. METHODS: Pragmatic cohort study to assess the effect of OAP and MBP in reducing SSI rate in 65 hospitals, comparing baseline phase (BP: 2007-2015) with implementation phase (IP: 2016-2019). To compare the results, a logistic regression model was established. RESULTS: Out of 34,421 colorectal operations, 5180 had SSIs (15.05%). Overall SSI rate decreased from 18.81% to 11.10% in BP and IP, respectively (OR 0.539, CI95 0.507-0.573, p < 0.0001). Information about bundle implementation was complete in 61.7% of cases. In a univariate analysis, OAP and MBP were independent factors in decreasing overall SSI, with OR 0.555, CI95 0.483-0.638, and OR 0.686, CI95 0.589-0.798, respectively; and similarly, organ/space SSI (O/S-SSI) (OR 0.592, CI95 0.494-0.710, and OR 0.771, CI95 0.630-0.944, respectively). However, only OAP retained its protective effect at both levels at multivariate analyses. CONCLUSIONS: oral antibiotic prophylaxis decreased the rates of SSI and O/S-SSI in a large series of elective colorectal surgery.

Low uptake of COVID-19 prevention behaviours and high socioeconomic impact of lockdown measures in South Asia: Evidence from a large-scale multi-country surveillance programme.

BACKGROUND: South Asia has become a major epicentre of the COVID-19 pandemic. Understanding South Asians' awareness, attitudes and experiences of early measures for the prevention of COVID-19 is key to improving the effectiveness and mitigating the social and economic impacts of pandemic responses at a critical time for the Region. METHODS: We assessed the knowledge, behaviours, health and socio-economic circumstances of 29,809 adult men and women, at 93 locations across four South Asian countries. Data were collected during the national lockdowns implemented from March to July 2020, and compared with data collected prior to the pandemic as part of an ongoing prospective surveillance initiative. RESULTS: Participants were 61% female, mean age 45.1 years. Almost half had one or more chronic disease, including diabetes (16%), hypertension (23%) or obesity (16%). Knowledge of the primary COVID-19 symptoms and transmission routes was high, but access to hygiene and personal protection resources was low (running water 63%, hand sanitisers 53%, paper tissues 48%). Key preventive measures were not widely adopted. Knowledge, access to, and uptake of COVID-19 prevention measures were low amongst people from disadvantaged socio-economic groups. Fifteen percent of people receiving treatment for chronic diseases reported loss of access to long-term medications; 40% reported symptoms suggestive of anxiety or depression. The prevalence of unemployment rose from 9.3% to 39.4% (P < 0.001), and household income fell by 52% (P < 0.001) during the lockdown. Younger people and those from less affluent socio-economic groups were most severely impacted. Sedentary time increased by 32% and inadequate fruit and vegetable intake increased by 10% (P < 0.001 for both), while tobacco and alcohol consumption dropped by 41% and 80%, respectively (P < 0.001), during the lockdown. CONCLUSIONS: Our results identified important knowledge, access and uptake barriers to the prevention of COVID-19 in South Asia, and demonstrated major adverse impacts of the pandemic on chronic disease treatment, mental health, health-related behaviours, employment and household finances. We found important sociodemographic differences for impact, suggesting a widening of existing inequalities. Our findings underscore the need for immediate large-scale action to close gaps in knowledge and access to essential resources for prevention, along with measures to safeguard economic production and mitigate socio-economic impacts on the young and the poor.

Update of the EAU/ESPU guidelines on urinary tract infections in children.

INTRODUCTION/BACKGROUND: Urinary tract infections (UTIs) are common in children and require appropriate diagnostic evaluation, management and follow-up. OBJECTIVE: To provide a summary of the updated European Association of Urology (EAU) guidelines on Pediatric Urology, which were first published in 2015 in European Urology. STUDY DESIGN: A structured literature review was performed of new publications between 2015 and 2020 for UTIs in children. The guideline was updated accordingly with relevant new literature. RESULTS: The occurrence of a UTI can be the first indication of anatomical abnormalities in the urinary tract, especially in patients with a febrile UTI. The basic diagnostic evaluation should include sufficient investigations to exclude urinary tract abnormalities, but should also be as minimally invasive as possible. In recent years, more risk factors have been identified to predict the presence of these anatomical anomalies, such as a non-E. Coli infection, high grade fever and ultrasound abnormalities. When these risk factors are factored into the diagnostic work-up, some invasive investigations can be omitted in a larger group of children. In addition to the treatment of active UTIs, it is also essential to prevent recurrent UTIs and consequent renal scarring. With the increase of antimicrobial resistance good antibiotic stewardship is needed. In addition, alternative preventative measures such as dietary supplements, bladder and bowel management and antibiotic prophylaxis could decrease the incidence of recurrent UTI. CONCLUSION: This paper is a summary of the updated 2021 EAU guidelines on Pediatric Urology. It provides practical considerations and flowcharts for the management and diagnostic evaluation of UTIs in children.

Compliance with preventative measures during the COVID-19 pandemic in the USA and Canada: Results from an online survey.

This study explored people's compliance with recommended preventative measures during early stages of the COVID-19 pandemic. An online survey was administered in June 2020 in the USA and Canada (N = 1,405). Regression analysis found that when controlling for other factors, age and political ideology were significant predictors of compliance with preventative measures. A content analysis of narrative answers of compliance/noncompliance found that the majority of individuals intended to comply with preventative measures, with primary reasons as social responsibility, self-protection, and protection of family members. Reasons identified for not complying were viewing preventative practices as unnecessary, getting mixed messages from various sources about effectiveness, distrust in government and inability to comply. This study informs social workers on intervention strategies on micro, mezzo and macro levels of practice.

Assessing the scale of adoption of sustainability practices by community pharmacies in Spain in the time of COVID-19.

Community pharmacies play a critical societal role and are well placed to enable the progress of national health systems towards sustainability. Nevertheless, there is a dearth of research which has been set up to understand sustainability practices adopted by community pharmacies and evaluate the drivers behind their adoption. This study undertook an exploratory analysis of 95 community pharmacies in Spain, measured their engagement with sustainability practices and assessed these practices in light of the COVID-19 pandemic. The results demonstrated the room for improvement in the adoption of green procurement practices in pharmacies and in their engagement with the community. Moreover, the study showcased that, during the COVID-19 crisis, the pharmacies with the largest extent of adoption of sustainability practices implemented preventative measures against the pandemic in a more diverse number during the first weeks of the lockdown, compared to their less sustainable counterparts. This indicates that, to build resilience to future (health) crises, the implementation of sustainable practices in community pharmacies should be encouraged by both policy makers and pharmaceutical firms.

The persistent breach between evidence and practice in the prevention of surgical site infection. Qualitative study.

BACKGROUND: Despite the dissemination of guidelines for surgical site infection (SSI) prevention, a gap between the theoretical measures and their compliance persists. Accurate estimates of the implementation of preventative measures is crucial before planning dissemination strategies. METHODS: A web-based survey was distributed to members of 11 Associations of operative nurses and surgeons. Questions aimed to determine their awareness of evidence, personal beliefs and actual use of the main preventative measures. RESULTS: Of 1105 responders, 50.5% receive no feed-back of their SSI rate. Responders show a moderate rate of awareness of the recommendations about not removing hair, hair clipping, skin antisepsis with alcoholic solutions, and normothermia. Antibiotic prophylaxis is given for more than 24 h by 18.8% of respondents. Screening for S. aureus is performed by 27.6%. Hair removal by shaving is used by 16.6% of responders. The most common antiseptic solutions are alcoholic chlorhexidine (57.2%) and aqueous povidone (23.3%). 62.8% of surgeons allow the solution to air dry before applying surgical drapes. Adhesive drapes in the surgical field are used routinely in 33.4% of cases. Perioperative normothermia, glucose control and hyperoxia are used in 84.3%, 65.9% and 23.3% of cases. Antimicrobial sutures and negative pressure therapy are used by 20.2% and 43.5% of teams, respectively. Prior to closing the incision, 83.9% replace surgical instruments always or selectively. Wound irrigation before closing is used in 78.1% of cases, mostly with saline. Check-lists, standardized orders, surveillance, feed-back and educational programs were rated most highly by respondents as a means to improve compliance with preventative guidelines, but few of these strategies were in place at their institutions. CONCLUSION: Gaps in the translation of evidence into practice remain in the prevention of SSI among different surgical specialities. Several areas for improvement have been identified, as some core prevention measures are not in common use.

Prevention of Prosthetic Joint Infection: From Traditional Approaches towards Quality Improvement and Data Mining.

A projected increased use of total joint arthroplasties will naturally result in a related increase in the number of prosthetic joint infections (PJIs). Suppression of the local peri-implant immune response counters efforts to eradicate bacteria, allowing the formation of biofilms and compromising preventive measures taken in the operating room. For these reasons, the prevention of PJI should focus concurrently on the following targets: (i) identifying at-risk patients; (ii) reducing "bacterial load" perioperatively; (iii) creating an antibacterial/antibiofilm environment at the site of surgery; and (iv) stimulating the local immune response. Despite considerable recent progress made in experimental and clinical research, a large discrepancy persists between proposed and clinically implemented preventative strategies. The ultimate anti-infective strategy lies in an optimal combination of all preventative approaches into a single "clinical pack", applied rigorously in all settings involving prosthetic joint implantation. In addition, "anti-infective" implants might be a choice in patients who have an increased risk for PJI. However, further progress in the prevention of PJI is not imaginable without a close commitment to using quality improvement tools in combination with continual data mining, reflecting the efficacy of the preventative strategy in a particular clinical setting.

Spectrum of Ocular Injuries and Visual Outcome Following Firework Injury to the Eye.

BACKGROUND: Ocular injury due to fireworks requires urgent ophthalmic assessment and management to preserve vision. METHODS: Spectrum of injury, type of intervention, visual outcome, and reasons for visual loss were assessed in consecutive patients presenting over 2 years with firework-related eye injury. The final visual outcome was recorded as best-corrected visual acuity. RESULTS: In the 96 patients (75 males) enrolled, 122 eyes were involved. Twenty-six patients had bilateral eye injury. The median (interquartile) age was 14 (8, 28.5) years. Injuries occurred during Diwali festival (59.4%) and funeral processions (20.8%); over half (53.8%) were bystanders. Injury was due to negligence (78%), device malfunction (12.5%), and attempts to reignite (5.2%) or recover failed device (4.2%). Presenting symptoms were redness (100%), pain (97%), watering (86%), and reduced vision (77%). Facial laceration, contusion, or hematoma occurred in 13 patients. The most frequent adnexal and ocular surface injuries were lid burns (57.3%), edema (44.2%), charred eyelashes (24.6%), and laceration (13.9%). Open-globe injury occurred in 8 eyes. Common anterior segment injuries were corneal epithelial defect (51.6%) and hyphema (20.5%). Posterior segment injuries included commotio retinae (13.1%) and Berlin's edema (7.4%). Surgical treatment was required in 15 eyes; 107 (88%) were managed conservatively. At study completion, of the 99 eyes evaluated, 21 had reduced visual acuity (<6/6) including 7 with monocular blindness. Factors associated with poor vision were open-globe injury (P < 0.001) and poor initial visual acuity (P = 0.05). CONCLUSIONS: Open-globe injury and poor visual acuity at presentation predict the final visual outcome. Monocular blindness following firecracker injury is common.

COVID-19: Key Concepts for the Surgeon. / COVID-19: conceptos clave para el cirujano.

In view of the current pandemic by SARS-CoV-2 it deems essential to understand the key concepts about the infection: its epidemiological origin, presentation, clinical course, diagnosis and treatment (still experimental in many cases). The knowledge about the virus is still limited, but as the pandemic progresses and the physiopathology of the disease is understood, new evidence is being massively published. Surgical specialists are facing an unprecedented situation: they must collaborate in the ER or medical wards attending these patients, while still needing to make decisions about surgical patients with probable COVID-19. The present narrative review aims to summarize the most relevant aspects and synthetize concepts on COVID-19 for surgeons.
