Standardized approach for extubation during extracorporeal membrane oxygenation in severe acute respiratory distress syndrome: a prospective observational study.

BACKGROUND: Extubation during extracorporeal oxygenation (ECMO) in severe acute respiratory distress syndrome (ARDS) has not been well studied. Despite the potential benefits of this strategy, weaning from ECMO before liberation from invasive mechanical ventilation remains the most frequent approach. Our aim was to evaluate the safety and feasibility of a standardized approach for extubation during ECMO in patients with severe ARDS. RESULTS: We conducted a prospective observational study to assess the safety and feasibility of a standardized approach for extubation during ECMO in severe ARDS among 254 adult patients across 4 intensive care units (ICU) from 2 tertiary ECMO centers over 6 years. This consisted of a daily assessment of clinical and gas exchange criteria based on an Extracorporeal Life Support Organization guideline, with extubation during ECMO after validation by a dedicated intensive care medicine specialist. Fifty-four (21%) patients were extubated during ECMO, 167 (66%) did not reach the clinical criteria, and in 33 (13%) patients, gas exchange precluded extubation during ECMO. At ECMO initiation, there were fewer extrapulmonary organ dysfunctions (lower SOFA score [OR, 0.88; 95% CI, 0.79-0.98; P = .02] with similar PaO2/FiO2) when compared with patients not extubated during ECMO. Extubation during ECMO associated with shorter duration of invasive mechanical ventilation (7 (4-18) vs. 32 (18-54) days; P < .01) and of ECMO (12 (7-25) vs. 19 (10-41) days; P = .01). This was accompanied by a lower incidence of hemorrhagic shock (2 vs. 11%; P = .05), but more cannula-associated deep vein thrombosis (49 vs. 31%; P = .02) and failed extubation (20 vs. 6%; P < .01). There were no increased major adverse events. Extubation during ECMO is associated with a lower risk of all-cause death, independently of measured confounding (adjusted logistic regression OR 0.23; 95% confidence interval 0.08-0.69, P = .008). CONCLUSIONS: A standardized approach was safe and feasible allowing extubation during ECMO in 21% of patients with severe ARDS, selecting patients who will have a shorter duration of invasive mechanical ventilation, ECMO course, and ICU stay, as well as fewer infectious complications, and high hospital survival.

Bleeding and Thrombotic Complications in COVID-19-Associated ARDS Requiring ECMO.

BACKGROUND: We analyzed bleeding and thrombotic complications in COVID-19-associated ARDS requiring extracorporeal membrane oxygenation (ECMO). METHODS: This was a single-center observational study of adult subjects undergoing ECMO for COVID-19 (n = 67) or all other cause of ARDS (n = 60), excluding trauma patients. RESULTS: In the COVID-19 group, duration of invasive mechanical ventilation prior to ECMO was lower (2 [0-4] d vs 3 [1-6] d) and ECMO retrieval less frequent (71% vs 87%). No significant differences were found in Simplified Acute Physiology Score II, Acute Physiology and Chronic Health Evaluation II (APACHE II), or in the in-hospital survival predicted by the Respiratory ECMO Survival Prediction score. During the first 7 d of ECMO support, the COVID-19 group presented higher platelets and fibrinogen, lower activated partial thromboplastin time, but no differences in D-dimer. Thrombotic complications were similar between groups. Higher rates of severe bleeding, namely airway bleeding (37.3% vs 15.0%) and hemothorax (13.4% vs 3.3%), were found in COVID-19, with lower hemoglobin and higher red blood cell transfusions. COVID-19 ARDS was associated with longer ECMO duration (47 [17-80] d vs 19 [12-30] d) and absence of a statistically significant difference concerning in-hospital mortality. CONCLUSIONS: COVID-19-associated ARDS requiring ECMO presented high rates of severe bleeding complications and a protracted course. Further studies are needed to clarify the risks and benefits of ECMO in severe COVID-19-associated ARDS.

Prevalence and Factors Associated with Metabolic Syndrome in Patients at a Psychosocial Care Center: A Cross-Sectional Study.

BACKGROUND: Metabolic syndrome (MS) is associated with greater risk of morbimortality and it has high prevalence in people with mental illness. OBJECTIVE: Estimate the prevalence of Metabolic Syndrome (MS) and its associated factors in the patients of a Psychosocial Care Center (CAPS in Brazilian Portuguese) in the city of Salvador, state of Bahia, Brazil. METHOD: Cross-sectional study set at CAPS in the city of Salvador-Bahia between August 2019 and February 2020. MS was evaluated according to the National Cholesterol Education Program's Adult Treatment Panel III. In addition to descriptive statistics, gross and adjusted prevalence ratios were described. RESULTS: MS was found in 100 (35.2%) individuals, 116 (40.9%) were obese and 165 (58.1%) had increased waist circumference. Polypharmacy was identified in 63 (22.3%) patients and 243 (85.9%) used antipsychotics. Under gross evaluation, women (PR = 1.88; 95%CI: 1.35-2.63) and those who used antidepressants (PR = 1.41; 95%CI: 1.05-1.88) showed an association with MS. After logistic regression, depression (PR = 1.86; 95%CI: 1.38-2.51), acanthosis (PR = 1.50; 95%CI: 1.18-1.90), use of antipsychotics (PR = 1.88; 95%CI: 1.13-2.75), and hypertriglyceridemic waist (PR = 3.33; 95%CI: 2.48-4.46) were associated with MS. CONCLUSION: The prevalence of MS signals multimorbidity among individuals with mental disorders and suggests a need for clinical screening.

Interaction between Work and Metabolic Syndrome: A Population-Based Cross-Sectional Study.

Metabolic syndrome (MS) is a clinical condition and a relevant risk factor in the development of cardiovascular diseases; it occurs as a result of lifestyle factors, e.g., work. The aim of this research was to estimate the interaction between work and MS among primary health care (PHC) nursing professionals in the state of Bahia, Brazil. A sectional multicentered study carried out in 43 municipalities in Bahia, whose study population consisted of nursing professionals. The exposure variables were occupation, professional exhaustion, and working time, and the outcome variable was MS. Interaction measures based on the additivity criteria were verified by calculating the excess risks due to the interactions and according to the proportion of cases attributed to the interactions and the synergy index. The global MS prevalence is 24.4%. There was a greater magnitude in the exposure group regarding the three investigated factors (average level occupation, professional exhaustion, and working time in PHC for more than 5 years), reaching an occurrence of 44.9% when compared to the prevalence of 13.1% in the non-exposure group (academic education, without professional burnout, and working time in PHC for up to 5 years). The study's findings showed a synergistic interaction of work aspects for MS occurrence among PHC nursing professionals.

Anxiety and dyslipidemia among primary health care professionals: A Cross-sectional study.

BACKGROUND: Cross-sectional studies point out important evidence between anxiety and dyslipdemic disorders in health workers. OBJECTIVE: Our main objective was to estimate the association between anxiety and dyslipidemia in Primary Health Care (PHC) nursing professionals in Feira de Santana, Bahia, Brazil. METHODS: A confirmatory cross-sectional study involving 376 PHC nursing professionals. Data collection occurred through the application of a questionnaire containing sociodemographic, labor and lifestyle issues, and the Beck Inventory for anxiety; to evaluate the lipid profile, the HDL-c, LDL-c, and triglycerides markers were evaluated. Descriptive, bivariate analysis and Logistic Regression were performed. RESULTS: The estimated prevalence of moderate/severe anxiety corresponded to 26.1% and dyslipidemia was 54.8%, with a statistically significant association between both of variables stratified by physical activity (PR = 2.69; 95% CI = 1.87-3.85) and (PR = 1.87; 95% CI = 1.53-2.28). CONCLUSIONS: There is a positive association between anxiety and dyslipidemia in Primary Health Care nursing professionals.

Effectiveness of auriculotherapy on stress reduction in health workers: a controlled randomized clinical trial.

OBJECTIVE: to assess the effectiveness of auriculotherapy in reducing occupational stress among Family Health Strategy workers during the COVID-19 pandemic. METHOD: a controlled randomized clinical trial divided into two groups, namely: auriculotherapy for stress group and placebo group. The Shapiro-Wilk test was used to assess data normality. The ANOVA test for repeated measures and the Tukey post-hoc test were applied to the group with normal samples. In turn, the Friedman and Durbin-Conover tests were employed in the group with non-normal distribution. Cohen's d index was calculated for the therapy effect size. A 95% significance level and p<0.05 were considered. RESULTS: the auriculotherapy group presented 16.3% and 23.7% reductions in occupational stress after the third and sixth auriculotherapy sessions, with Cohen's d indices of 1.12 (large effect) and 1.82 (very large effect), respectively. CONCLUSION: auriculotherapy proved to be effective in reducing occupational stress among Family Health Strategy workers during the COVID-19 pandemic. It is suggested that new studies are developed both during and after the pandemic in order to improve health workers' Quality of Life. ReBEC registration: RBR - 38hjyt3.

Assessing Brazilian Medical Student Awareness About Global Surgery: A Survey-Based Study.

BACKGROUND: Global surgery is an interdisciplinary field that advocates for access to equitable, affordable surgical services for all people. Engaging medical students in the field can strengthen the surgical workforce in low- and middle-income countries. We aim to investigate Brazilian medical students' acknowledgment of global surgery and their preferred learning platforms. MATERIALS AND METHODS: We performed a cross-sectional study through an anonymous Portuguese survey on Google Forms, consisting of 30 mixed multiple-choice and five-point Likert scale questions. Students enrolled in a Brazilian medical school from the second to sixth academic year fulfilled inclusion criteria. The association between qualitative variables was assessed using Chi-square, Fisher's exact test, or binary logistic model. RESULTS: We received 1,345 responses from 208 medical schools. Only 20.9% (282/1,345) of participants reported awareness of global surgery, who were predominantly female. 96.5% (1,298/1,345) declared interest in knowing more about global surgery and participants indicated social media (71.6%, 202/282) as the prevalent manner to gain awareness on it, followed by webinars (63.5%, 179/282). Extracurricular classes were the most preferable option among students (61.4%, 827/1,345) to get acquainted with the field, followed by internships (59.4%, 812/1,345), workshops (57%, 767/1,345), and social media (53.4%, 730/1,345). The main obstacles to pursue a global surgery career were lack of national opportunities (32%, 431/1,345) and adequate training (25.4%, 341/1,345). CONCLUSION: We outlined the most strategic pathways to raising awareness on global surgery among Brazilian medical students, providing relevant insights on its education in similar settings.

Effect of immunonutrition on serum levels of C-reactive protein and lymphocytes in patients with COVID-19: a randomized, controlled, double-blind clinical trial.

INTRODUCTION: Introduction: patients with COVID-19 undergo changes in leukocyte count, respiratory disorders, and an increase in inflammatory substances. To improve the inflammatory condition, some nutrients can be used, including arginine, omega-3 fatty acids and nucleotides. This study aims to evaluate how oral immunonutrient supplements affects serum C-reactive protein (CRP) levels and lymphocyte count in patients with COVID-19. Methods: in this double-blind clinical trial, we randomized 43 adult patients with COVID-19 to receive a standard high-protein normocaloric supplement (control) or an immunonutrient-enriched supplement (experiment) for 7 days. The primary outcome was to evaluate changes in total lymphocyte count and serum level of CRP. The assessment of risk and nutritional status of these patients was also performed. Results: forty-three patients with mean age of 41.5 (± 1.8) years were followed up, 39.5 % of them women. The mean body mass index was 27.6 (± 0.8) kg/m² and 58.1 % had low nutritional risk. In the experiment group, there was a CRP reduction of 23.6 (± 7.5) mg/L, while in the control branch the decrease was 14.8 (± 12.1) mg/L (p = 0.002). There was an increase in lymphocytes in the experiment group (+367.5 ± 401.8 cells/mm³) and a reduction in the control group (-282.8 ± 327.8 cells/mm³), although there was no statistical significance (p = 0.369). Relative risk (RR) of treatment in reducing CRP by 30 % or more was 4.45 (p < 0.001; 95 % CI, 1.79-11.07). RR in increasing lymphocyte count by 30 % or more was 1.28 (p = 0.327; 95 % CI, 0.67-2.45). Conclusion: we conclude that immunonutrient supplements seem to reduce CRP levels more than standard high-protein normocaloric supplements.

INTRODUCCIÓN: Introducción: los pacientes con COVID-19 sufren cambios en el recuento de leucocitos, trastornos respiratorios y aumento de sustancias inflamatorias. Para mejorar la condición inflamatoria se pueden usar algunos nutrientes, como la arginina, los ácidos grasos omega-3 y los nucleótidos. Este estudio tiene como objetivo evaluar cómo los suplementos de inmunonutrientes orales afectan a los niveles séricos de proteína C-reactiva (PCR) y al recuento de linfocitos en pacientes con COVID-19. Métodos: en este ensayo clínico doble ciego, aleatorizamos a 43 pacientes adultos con COVID-19 para recibir un suplemento normocalórico estándar alto en proteínas (control) o un suplemento enriquecido con inmunonutrientes (experimento) durante 7 días. El resultado primario fue evaluar los cambios en el recuento total de linfocitos y el nivel sérico de PCR. También se realizó la evaluación del riesgo y el estado nutricional de estos pacientes. Resultados: cuarenta y tres pacientes con edad media de 41,5 (± 1,8) años fueron seguidos, el 39,5 % de ellos mujeres. El índice de masa corporal medio fue de 27,6 (± 0,8) kg/m² y el 58,1 % tenían bajo riesgo nutricional. En el grupo experimental hubo una reducción de la PCR de 23,6 (± 7,5) mg/L, mientras que en la rama de control la disminución fue de 14,8 (± 12,1) mg/L (p = 0,002). Hubo un aumento de linfocitos en el grupo experimental (+367,5 ± 401,8 células/mm³) y una reducción en el grupo de control (-282,8 ± 327,8 células/mm³), aunque no hubo significación estadística (p = 0,369). El riesgo relativo (RR) del tratamiento para reducir la PCR en un 30 % o más fue de 4,45 (p < 0,001; IC 95 %: 1,79-11,07). El RR en el aumento del recuento de linfocitos en un 30 % o más fue de 1,28 (p = 0,327; IC 95 %: 0,67-2,45). Conclusión: se concluye que los suplementos de inmunonutrientes parecen reducir los niveles de PCR más que los suplementos normocalóricos estándar altos en proteína.

May Measurement Month 2019: an analysis of blood pressure screening results from Brazil.

The aim of this study is to describe the results of the May Month Measurement (MMM) campaign implemented in Brazil, in 2019. Questionnaire data were collected and three measures of blood pressure (BP) were performed. The sample consisted of 13 476 individuals, 58.2% were white, 60.8% were women. The average age was 46.3 (18.6) years. Of all 13 476 participants, 6858 (50.9%) had hypertension defined as a systolic BP ≥140 mmHg or a diastolic BP ≥90 mmHg or being on anti-hypertensive medication. Of those with hypertension, 68.8% were aware of their diagnosis, 65.3% were on antihypertensive medication, and 36.1% had controlled BP (<140/90 mmHg). In addition, of 4479 participants on anti-hypertensive medication, 55.2% had controlled BP. The use of anti-hypertensive medication was associated with higher systolic (P < 0.001) and diastolic BP (P < 0.001) and having diabetes with higher systolic BP (P < 0.001). Previous hypertension in pregnancy was associated with higher systolic (P = 0.038) and diastolic BP (P = 0.003), and smoking was associated with higher systolic BP (P < 0.001). Lastly, obese and overweight individuals showed significantly higher systolic (P < 0.001) and diastolic (P < 0.001) BP. The Brazilian MMM19 data demonstrate that strategies to increase awareness of hypertension and a better control of the risk factors are still needed.

Pressão arterial central e risco cardiovascular / Central blood pressure and cardiovascular risk

Pressão Central, como o nome indica, é uma medida hemodinâmica semelhante a pressão arterial convencional porém avaliada de forma indireta por equipamento especifico, que avalia estes parâmetros na saída do sangue na raiz da aorta. Esta medida tem uma maior confiabilidade pois prediz de forma mais acurada os riscos de adoecimento e morte cardiovascular. Isto ocorre, pois a a onda de pulso (OP) ao percorrer os trajetos arteriais sofrem ampliações e importantes modificações no seu contorno deformando o valor original. Embora seja mais precisa em valores, ainda não é usado de rotina na pratica clinica por razoes de custos dos seus equipamentos e provavelmente por exigir habilidades maiores que as medidas captadas pelo equipamentos de mensuração periférica

Central pressure, as the name implies, is a hemodynamic measure similar to conventional blood pressure, but indirectly assessed by specific equipment, which evaluates these parameters at the blood outlet at the root of the aorta. This measure has greater confidence because it more accurately predicts the risks of cardiovascular disease and death. This occurs because the pulse wave (OP) when traversing the arterial paths provides enlargements and modifications in its contour, deforming the original value. Although it is more precise in terms of values, it is not yet routinely used in clinical practice for reasons of the cost of its equipment and probably because it requires greater needs than measures captured by peripheral measurement equipment

The Prevalence of Abdominal Adiposity among Primary Health Care Physicians in Bahia, Brazil: An Epidemiological Study.

BACKGROUND: Labor activities are demanding for workers and can induce occupational stress. Primary health care (PHC) workers have faced problems that can lead to the development of stress and abdominal obesity. The aim of this study was to estimate the prevalence of abdominal adiposity among primary health care physicians in the metropolitan mesoregion of Salvador, Bahia. METHODS: This is a cross-sectional study conducted with physicians from the family health units (FHUs) of the metropolitan mesoregion of Salvador, Bahia, Brazil. The number of FHUs corresponded to 41 teams (52 physicians). Anamnesis was performed and a questionnaire was applied. The clinical examination consisted of measuring waist circumference (WC), blood pressure levels (BP), and body mass index (BMI), as well as examining for acanthosis nigricans. Blood samples were collected for biochemical dosages. The data obtained were analyzed by SPSS version 22.0. RESULTS: The sample included 41 physicians (response rate: 78.8%), of which 18 were women (44.0%). The percentage of overweight participants represented by BMI was 31.7%. The hypertriglyceridemia prevalence was 29.2%. HDL-c was low in 48.7% of the participants. The waist circumference measurement revealed a prevalence of abdominal adiposity of 38.8% (women) and 34.8% (men). CONCLUSIONS: Medical professionals in PHC are more susceptible to having higher abdominal adiposity, especially female physicians.

Relationship between the COVID-19 pandemic, binge eating, and mental suffering in health professionals in Brazil: a cross-sectional study.

Introduction: The high levels of anxiety, stress, and depression produced by the global Coronavirus disease 2019 pandemic could trigger eating disorders. Health professionals are more exposed to these changes due to their work environment. Objectives: To evaluate the relationship between the COVID-19 pandemic and the onset of binge eating disorder and psychiatric disorders in Brazilian health professionals. Methods: This descriptive, prospective, cross-sectional study interviewed 219 Brazilian health professionals between June and October 2020 using an online questionnaire. The 7-Item Binge Eating Disorder Screener was used to diagnose binge eating disorder. The Self-Reporting Questionnaire was used to assess psychiatric disorders. The statistical analysis included calculation of absolute frequency, relative frequency, mean and standard deviation. Contingency coefficient C was used to determine the association between the variables. Results: A total of 35 (16%) participants reported symptoms related to binge eating disorder, while 131 (59.8%) reported psychiatric symptoms. There was an association between binge eating disorder, psychiatric disorders, and body mass index. Conclusions: Our findings suggest the onset of psychiatric disorders and binge eating disorders in these professionals and that elevated body mass index is directly associated with these disorders.

Successful Unilateral Surgical Approach to Internal Globus Pallidus and Ventral Intermediate Nucleus of the Thalamus in 3 Cases of Myoclonus-Dystonia Syndrome.

Surgical approaches of internal globus pallidus (GPi) and ventral intermediate thalamic nucleus (Vim) have been used to treat different movement disorders. Three subjects with myoclonus-dystonia syndrome were surgically treated, one of them with GPi and Vim stimulation, while radiofrequency ablation of these structures was performed in the other 2 subjects. Surgical approach of both targets was performed simultaneously on each subject. Mean follow-up was of 33.3 months (22-48 months), the Unified Myoclonus Rating Scale action myoclonus (AM), functional tests (FT), patient questionnaire (PQ) sub-scores, and the Unified Dystonia Rating Scale (UDRS) were used during assessments. Improvement in all scales were seen 6 months after surgery (AM: 74%, FT: 60%, PQ: 63%, UDRS: 65%), and this benefit persisted throughout follow-up (AM: 61%, FT:62%, PQ: 65%, UDRS: 86%). No adverse events were noticed. Simultaneous unilateral procedures of GPi and Vim by either stimulation or ablation techniques improve both motor and functional scores in myoclonus-dystonia syndrome.

Dose dependence of treatment-related adverse events for immune checkpoint inhibitor therapies: a model-based meta-analysis.

Programmed cell death-1 (PD-1) and/or cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) immune checkpoint inhibitor (ICI) treatments are associated with adverse events (AEs), which may be dependent on ICI dose. Applying a model-based meta-analysis to evaluate safety data from published clinical trials from 2005 to 2018, we analyzed the dose/exposure dependence of ICI treatment-related AE (trAE) and immune-mediated AE (imAE) rates. Unlike with PD-1 inhibitor monotherapy, CTLA-4 inhibitor monotherapy exhibited a dose/exposure dependence on most AE types evaluated. Furthermore, combination therapy with PD-1 inhibitor significantly strengthened the dependence of trAE and imAE rates on CTLA-4 inhibitor dose/exposure.

Effects of parenteral glutamine in critically ill surgical patients: a systematic review and meta-analysis / Efectos de la glutamina parenteral en pacientes quirúrgicos críticos: revisión sistemática y metaanálisis

INTRODUCTION: glutamine (GLN), the most abundant non-essential amino acid in the plasma, tends to be rapidly depleted in cells in situations of metabolic stress. Some studies have demonstrated the benefits of GLN supplementation on mortality, infection, and length of hospital stay. The objective of this review was to analyze whether parenteral supplementation with GLN has any relevant effect in critically ill surgical patients. METHODS: based on a systematic database search, randomized clinical trials (RCTs) published since 1985 were included if they had evaluated the effect of parenteral GLN supplementation in critical surgical patients. The statistical analysis was performed using the RevMan 5.3 software. RESULTS: seven RCTs were eligible for the meta-analysis. Parenteral glutamine supplementation was associated with a non-significant 24 % reduction in mortality (RR = 0.76; 95 % CI: 0.50-1.15). Infections were significantly reduced (RR = 0.60; 95 % CI: 0.45-0.80), and length of hospital stay was 4.09 days shorter (95 % CI: -6.71 to -1.46). CONCLUSION: parenteral GLN usage in critical surgical patients seems to decrease infection and length of hospital stay, but we could not demonstrate a significant reduction in mortality

INTRODUCCIÓN: la glutamina (GLN), el aminoácido no esencial más abundante en el plasma, tiende a agotarse rápidamente en las células en situaciones de estrés metabólico. Algunos estudios han demostrado beneficios de la suplementación con GLN en términos de reducción de la mortalidad, las infecciones y la duración de la hospitalización. El objetivo de esta revisión es analizar si la suplementación parenteral de GLN tiene algún efecto relevante para los pacientes quirúrgicos en estado crítico. MÉTODOS: basado en una búsqueda sistemática de bases de datos, se incluyeron ensayos clínicos aleatorizados (ECA) publicados desde 1985 si estos habían evaluado el efecto de la suplementación parenteral de GLN en pacientes quirúrgicos críticos. El análisis estadístico se realizó utilizando el software RevMan 5.3. RESULTADOS: siete ECA fueron elegibles para el metaanálisis. La suplementación parenteral de glutamina se asoció a una reducción no significativa del 24 % en la mortalidad (RR = 0,76; IC 95 %: 0,50-1,15). Las infecciones se redujeron significativamente (RR = 0,60; IC 95 %: 0,45-0,80) y la duración de la estancia de hospitalización fue 4,09 días menor (IC 95 %: -6,71 a -1,46). CONCLUSIÓN: el uso de GLN parenteral en pacientes quirúrgicos críticos parece disminuir las infecciones y la duración de la estancia hospitalaria, pero no pudimos demostrar una reducción significativa de la mortalidad

Response to SARS-CoV-2 Pandemic in a Non-COVID-19 Designated Latin-American Neurosurgery Department.

Background: Mexico declared the first case of novel coronavirus disease (COVID-19) in February 2020. At the time we write this article, our country is facing a community spread phase, expecting a rapid increase in the number of cases and fatalities. The Fray Antonio Alcalde Civil Hospital of Guadalajara has been declared a non-COVID-19 hospital with the mission of providing care to patients already registered and also those transferred from neurosurgical departments of neighboring centers, which have been converted into COVID-19 only hospitals. Methods: An organized response regarding personnel, surgical case selection, operating room behavior, and facility reorganization were designed to prevent an internal coronavirus outbreak in the neurosurgery department at the Fray Antonio Alcalde Civil Hospital of Guadalajara. Results: Distancing actions by the staff and residents, including ward case discussions, neurosurgery rounds, and classes, will be carried out virtually. We classified neurosurgical patients into 4 groups depending on whether their condition demands care in 0-6 hours, 6-48 hours, 48 hours to 14 days, and >14 days. Subsequently, a questionnaire with epidemiologic, radiologic, clinical, and serologic criteria will be applied to determine the risk of COVID-19 infection to define to which area they are going to be transferred according to the different risk zones in our facility. Conclusions: Despite not being a COVID-19 center, we consider all patients at the neurosurgical ward and staff members as asymptomatic carriers or infected in the preclinical period. Specific measures must be taken to ensure the safety and care of neurosurgical patients and medical staff during the community spread phase.
