COVID-19 in Brazil: Historical cases, disease milestones, and estimated outbreak peak

Perceived Impact of Coronavirus Disease 2019 on Surgical Training: A Brazilian Survey

INTRODUCTION

Recent studies revealed that coronavirus disease 2019 (COVID-19) negatively impacted residency programs worldwide, particularly procedure-based programs. However, most studies are from high-income countries, with scarce data from low- and middle-income countries. Pandemic effects on surgical training were likely worse in strictly apprenticeship models relying heavily on surgical volume as opposed to competency-based programs. Notably, training programs in Brazil and other low- and middle-income countries follow these strict apprenticeship style frameworks. In this study, we aimed to evaluate the trainees' perceptions of the impact of COVID-19 on their Brazilian surgical programs.

METHODS

A cross-sectional study was performed using an anonymous survey in Portuguese, distributed via social media platforms to surgical residents enrolled in Brazilian surgery programs. Data collection took place from August 2021 to May 2022. The survey contained 30 questions on the perception of the impact of COVID-19 on surgical training.

RESULTS

One-hundred sixty-two residents from 17 different surgical specialties and all five regions of Brazil responded to the survey. Of 162 residents, 145 (89%) believed the pandemic negatively impacted their surgical training. Furthermore, of 162 residents, 153 (94%) reported that elective surgical volume decreased during the pandemic and 91 (56%) were redeployed to assist with COVID-19 management. As a result, 102 of 162 (63%) residents believed their surgical skills were negatively impacted by COVID-19. Yet, 95 of 162 (59%) residents reported their residency programs did not offer resources to mitigate the pandemic's impact on training. Of 162 residents, 57 (35%) reported they did not feel on track for graduation, with no statistical difference between responses by year of residency (P = 0.083). Additionally, 124 of 162 (77%) residents reported that the pandemic negatively affected their mental health, most commonly related to stress at work, stress about transmitting COVID-19, and loss in surgical training.

CONCLUSIONS

Most of the surveyed Brazilian surgical residents felt the COVID-19 pandemic negatively impacted their training. This leads to believe that the detrimental impacts of the pandemic exposed preexisting weaknesses in the Brazilian surgical training model's dependence on a strict apprenticeship model. Our findings suggest a crucial need to redesign surgical education programs to make residency programs more prepared for changes in surgical volume, evolve the apprenticeship model to competency-based approaches, and unify surgical training standards in low- and middle-income countries.

COVID-19-associated coagulopathy and acute kidney injury in critically ill patients

OBJECTIVE

The incidence of thrombotic events and acute kidney injury is high in critically ill patients with COVID-19. We aimed to evaluate and compare the coagulation profiles of patients with COVID-19 developing acute kidney injury versus those who did not, during their intensive care unit stay.

METHODS

Conventional coagulation and platelet function tests, fibrinolysis, endogenous inhibitors of coagulation tests, and rotational thromboelastometry were conducted on days 0, 1, 3, 7, and 14 following intensive care unit admission.

RESULTS

Out of 30 patients included, 13 (43.4%) met the criteria for acute kidney injury. Comparing both groups, patients with acute kidney injury were older: 73 (60-84) versus 54 (47-64) years, p=0.027, and had a lower baseline glomerular filtration rate: 70 (51-81) versus 93 (83-106) mL/min/1.73m2, p=0.004. On day 1, D-dimer and fibrinogen levels were elevated but similar between groups: 1780 (1319-5517) versus 1794 (726-2324) ng/mL, p=0.145 and 608 (550-700) versus 642 (469-722) g/dL, p=0.95, respectively. Rotational thromboelastometry data were also similar between groups. However, antithrombin activity and protein C levels were lower in patients who developed acute kidney injury: 82 (75-92) versus 98 (90-116), p=0.028 and 70 (52-82) versus 88 (78-101) µ/mL, p=0.038, respectively. Mean protein C levels were lower in the group with acute kidney injury across multiple time points during their stay in the intensive care unit.

CONCLUSION

Critically ill patients experiencing acute kidney injury exhibited lower endogenous anticoagulant levels. Further studies are needed to understand the role of natural anticoagulants in the pathophysiology of acute kidney injury within this population.

A beta regression analysis of COVID-19 mortality in Brazil

Brazil was one of the countries most impacted by the COVID-19 pandemic, with a cumulative total of nearly 700,000 deaths by early 2023. The country's federative units were unevenly affected by the pandemic and adopted mitigation measures of different scopes and intensity. There was intense conflict between the federal government and state governments over the relevance and extent of such measures. We build a simple regression model with good predictive power on state COVID-19 mortality rates in Brazil. Our results reveal that the federative units' urbanization rate and per capita income are important for determining their mean mortality rate and that the number of physicians per 100,000 inhabitants is important for modeling the mortality rate precision. Based on the fitted model, we obtain approximations for the levels of administrative efficiency of local governments in dealing with the pandemic.

COVID-19 in patients with paracoccidioidomycosis

INTRODUCTION

In 2020, we reported the first patient with concomitant COVID-19 and paracoccidioidomycosis (PCM). Since then, no other cases have been recorded in the literature. We aim to update information on the occurrence of COVID-19 in patients with PCM followed at a reference center for infectious diseases at Rio de Janeiro, Brazil.

METHODS

We reviewed the medical records from patients diagnosed with PCM who presented with clinical symptoms, radiological findings, and/or laboratory diagnosis of COVID-19 at any time during their acute or follow-up care. The clinical profiles of these patients were described.

RESULTS

Between March 2020 and September 2022, we identified six individuals with COVID-19 among the 117 patients with PCM evaluated. The median age was 38 years and the male to female ratio 2:1. Most patients (n = 5) presented for evaluation due to acute PCM. The severity of COVID-19 ranged from mild to severe in acute PCM and only the single patient with chronic PCM died.

CONCLUSIONS

There is a range of disease severity in COVID-19 and PCM co-infection and concomitant disease may represent a severe association, especially in the chronic type of the mycosis with pulmonary involvement. As COVID-19 and chronic PCM share similar clinical aspects and PCM is neglected, it is probable that COVID-19 has been hampering simultaneous PCM diagnosis, which can explain the absence of new co-infection reports. With the continued persistence of COVID-19 globally, these findings further suggest that more attention by providers is necessary to identify co-infections with Paracoccidioides.

Comparison of contraceptive sales before and during the COVID-19 pandemic in Brazil

OBJECTIVE

The aim of the study was to assess the impact of the COVID-19 pandemic on sales of modern contraceptive methods in Brazil.

METHODS

Monthly sales data were analysed of short-acting reversible contraceptive methods and long-acting reversible contraceptive (LARC) methods (implants and intrauterine contraception) and COVID-19 related deaths. Contraceptive methods were grouped as follows: emergency contraception (EC); oral contraception, vaginal rings and transdermal patches; injectable contraception; LARC methods including the copper intrauterine device (Cu-IUD); and LARC methods excluding the Cu-IUD.

RESULTS

Contraceptive sales showed a non-significant increase in 2020 compared with the previous year; average sales ranged from 12.8 to 13.0 million units per month. Sales of injectable contraceptives increased between March and June 2020 and EC pills between June and July 2020; the variation in sales of pills, patches and rings was not significant. Sales of the levonorgestrel-releasing intrauterine system (LNG-IUS) and the etonogestrel (ENG) implant showed three patterns: a decrease in sales between February and May 2020 (coinciding with the closure of family planning services), an increase in sales after May 2020 (coinciding with the first COVID-19-related deaths), and a further increase in sales after July 2020 (corresponding to the increasing number of deaths from COVID-19).

CONCLUSION

The COVID-19 pandemic has disrupted the Brazilian health care system. Since many family planning clinics were closed, sales of most modern contraceptives fell during 2020; however, the increase in sales of the LNG-IUS and ENG implant in the private sector indicates inequitable access to modern contraceptive methods.

Poor prognosis indicators of type-2 diabetic COVID-19 patients

Diabetes is associated with a worse prognosis and a high risk of morbidity and mortality in COVID-19 patients. We aimed to evaluate the main factors involved in the poor prognosis in diabetic patients. A total of 984 patients diagnosed with COVID-19 admitted to the hospital were included in this study. Patients were first divided into type-2 diabetic (DM+) and non-diabetic (DM–) groups. The participants were analyzed based on the National Early Warning Score (NEWS) and on the Quick-Sequential Organ Failure Assessment (qSOFA) to find the best prognostic risk score for our study. The DM+ and DM– groups were divided into non-severe and severe groups. Comparative and correlative analyses were used to identify the physiological parameters that could be employed for creating a potential risk indicator for DM+ COVID-19 patients. We found a poorer prognosis for the DM+ COVID-19 patients with a higher ICU admission rate, mechanical ventilation rate, vasopressor use, dialysis, and longer treatment times compared with the DM– group. DM+ COVID-19 patients had increased plasma glucose, lactate, age, urea, NEWS, and D-dimer levels, herein referred to as the GLAUND set, and worse prognosis and outcomes when compared with infected DM– patients. The NEWS score was a better indicator for assessing COVID-19 severity in diabetic patients than the q-SOFA score. In conclusion, diabetic COVID-19 patients should be assessed with the NEWS score and GLAUND set for determining their prognosis COVID-19 prognosis.

Association between government policy and delays in emergent and elective surgical care during the COVID-19 pandemic in Brazil: a modeling study

Background

The impact of public health policy to reduce the spread of COVID-19 on access to surgical care is poorly defined. We aim to quantify the surgical backlog during the COVID-19 pandemic in the Brazilian public health system and determine the relationship between state-level policy response and the degree of state-level delays in public surgical care.

Methods

Monthly estimates of surgical procedures performed per state from January 2016 to December 2020 were obtained from Brazil's Unified Health System Informatics Department. Forecasting models using historical surgical volume data before March 2020 (first reported COVID-19 case) were constructed to predict expected monthly operations from March through December 2020. Total, emergency, and elective surgical monthly backlogs were calculated by comparing reported volume to forecasted volume. Linear mixed effects models were used to model the relationship between public surgical delivery and two measures of health policy response: the COVID-19 Stringency Index (SI) and the Containment & Health Index (CHI) by state.

Findings

Between March and December 2020, the total surgical backlog included 1,119,433 (95% Confidence Interval 762,663–1,523,995) total operations, 161,321 (95%CI 37,468–395,478) emergent operations, and 928,758 (95%CI 675,202–1,208,769) elective operations. Increased SI and CHI scores were associated with reductions in emergent surgical delays but increases in elective surgical backlogs. The maximum government stringency (score = 100) reduced emergency delays to nearly zero but tripled the elective surgical backlog.

Interpretation

Strong health policy efforts to contain COVID-19 ensure minimal reductions in delivery of emergent surgery, but dramatically increase elective backlogs. Additional coordinated government efforts will be necessary to specifically address the increased elective backlogs that accompany stringent responses.

Transition to clinical practice during the COVID-19 pandemic: a qualitative study of young doctors' experiences in Brazil and Ireland

OBJECTIVES

To explore and compare the perspectives of junior doctors in Brazil and Ireland regarding transition and professional socialisation during the COVID-19 pandemic, with the purpose of identifying better ways to support doctors as they assume their new professional role.

DESIGN

27 semistructured interviews. Transcripts were analysed using qualitative thematic analysis. Cruess' framework of professional socialisation in medicine supported the interpretation of these data.

SETTING

Public health hospitals across four Brazilian states (Santa Catarina, São Paulo, Ceará, Paraíba) and County Cork in the South of Ireland.

PARTICIPANTS

Twenty-seven male and female medical junior doctors who had graduated between November 2019 and April 2020.

RESULTS

Fourteen Brazilian and 13 Irish junior doctors were interviewed for this study. Entry to clinical practice during the pandemic had a significant impact on factors influencing the professional socialisation of junior doctors. This impact was reflected across the following six thematic areas: lack of preparedness; disrupted trajectory of role adaptation; fewer opportunities for experiential learning; solidarity and isolation; altered interactions with patients; challenges to health and well-being.

CONCLUSIONS

Transition to clinical practice is an important stage in junior doctors' professional socialisation and identity formation. The COVID-19 pandemic created the opportunity for medical graduates to enter the workforce earlier than usual. Entering the workforce during this period created a lack of confidence among junior doctors concerning the boundaries of their new role and responsibilities, while simultaneously disrupting their social integration. Priorities to mitigate the impact of COVID-19 and future pandemics on this transition are presented.

Values and COVID-19 worries: The importance of emotional stability traits

We examined the relationship between emotional stability as a more stable personality trait and COVID-related worries with basic human values in a Brazilian sample (N = 578) that is strongly affected by COVID-19. We tested whether emotional stability would moderate the effect of infection and economic worries on personal values. In line with predictions, we found that infection worries were more strongly related to Security values, especially among individuals with less emotional stability, whereas economic worries were more strongly correlated with Power values, in particular among individuals with less emotional stability. Findings for Achievement values suggested perceived behavioral control effects for individuals high in Emotional Stability. Our findings provide insights into possible longer-term psychological effects of the current pandemic. Emotional dynamics in connection with worries created by the pandemic could influence values of importance for societal functioning in the short to medium term.

A simple mathematical model for the evaluation of the long first wave of the COVID-19 pandemic in Brazil

We propose herein a mathematical model to predict the COVID-19 evolution and evaluate the impact of governmental decisions on this evolution, attempting to explain the long duration of the pandemic in the 26 Brazilian states and their capitals well as in the Federative Unit. The prediction was performed based on the growth rate of new cases in a stable period, and the graphics plotted with the significant governmental decisions to evaluate the impact on the epidemic curve in each Brazilian state and city. Analysis of the predicted new cases was correlated with the total number of hospitalizations and deaths related to COVID-19. Because Brazil is a vast country, with high heterogeneity and complexity of the regional/local characteristics and governmental authorities among Brazilian states and cities, we individually predicted the epidemic curve based on a specific stable period with reduced or minimal interference on the growth rate of new cases. We found good accuracy, mainly in a short period (weeks). The most critical governmental decisions had a significant temporal impact on pandemic curve growth. A good relationship was found between the predicted number of new cases and the total number of inpatients and deaths related to COVID-19. In summary, we demonstrated that interventional and preventive measures directly and significantly impact the COVID-19 pandemic using a simple mathematical model. This model can easily be applied, helping, and directing health and governmental authorities to make further decisions to combat the pandemic.

Prediction studies of the epidemic peak of coronavirus disease in Brazil via new generalised Caputo type fractional derivatives

The first reported case of coronavirus disease (COVID-19) in Brazil was confirmed on 25 February 2020 and then the number of symptomatic cases produced day by day. In this manuscript, we studied the epidemic peaks of the novel coronavirus (COVID-19) in Brazil by the successful application of Predictor–Corrector (P-C) scheme. For the proposed model of COVID-19, the numerical solutions are performed by a model framework of the recent generalized Caputo type non-classical derivative. Existence of unique solution of the given non-linear problem is presented in terms of theorems. A new analysis of epidemic peaks in Brazil with the help of parameter values cited from a real data is effectuated. Graphical simulations show the obtained results to classify the importance of the classes of projected model. We observed that the proposed fractional technique is smoothly work in the coding and very easy to implement for the model of non-linear equations. By this study we tried to exemplify the roll of newly proposed fractional derivatives in mathematical epidemiology. The main purpose of this paper is to predict the epidemic peak of COVID-19 in Brazil at different transmission rates. We have also attempted to give the stability analysis of the proposed numerical technique by the reminder of some important lemmas. At last we concluded that when the infection rate increases then the nature of the diseases changes by becoming more deathly to the population.

Evaluating clinical characteristics studies produced early in the Covid-19 pandemic: A systematic review

OBJECTIVES

Clinical characterisation studies have been essential in helping inform research, diagnosis and clinical management efforts, particularly early in a pandemic. This systematic review summarises the early literature on clinical characteristics of patients admitted to hospital, and evaluates the quality of evidence produced during the initial stages of the pandemic.

METHODS

MEDLINE, EMBASE and Global Health databases were searched for studies published from January 1st 2020 to April 28th 2020. Studies which reported on at least 100 hospitalised patients with Covid-19 of any age were included. Data on clinical characteristics were independently extracted by two review authors. Study design specific critical appraisal tools were used to evaluate included studies: the Newcastle Ottawa scale for cohort and cross sectional studies, Joanna Briggs Institute checklist for case series and the Cochrane collaboration tool for assessing risk of bias in randomised trials.

RESULTS

The search yielded 78 studies presenting data on 77,443 people. Most studies (82%) were conducted in China. No studies included patients from low- and middle-income countries. The overall quality of included studies was low to moderate, and the majority of studies did not include a control group. Fever and cough were the most commonly reported symptoms early in the pandemic. Laboratory and imaging findings were diverse with lymphocytopenia and ground glass opacities the most common findings respectively. Clinical data in children and vulnerable populations were limited.

CONCLUSIONS

The early Covid-19 literature had moderate to high risk of bias and presented several methodological issues. Early clinical characterisation studies should aim to include different at-risk populations, including patients in non-hospital settings. Pandemic preparedness requires collection tools to ensure observational studies are methodologically robust and will help produce high-quality data early on in the pandemic to guide clinical practice and public health policy.

Teaching Online during the COVID-19 Pandemic: A Phenomenological Study of Physical Therapist Faculty in Brazil, Cyprus, and The United States

The COVID-19 pandemic led to a global transition from in-person to online instruction leaving many higher education faculty with little time or training for this responsibility. Physical therapist education programs were especially impacted since a large part of the development of skills rely on face-to-face onsite practice. This phenomenological study explored the perceptions of physical therapist educators in three countries—Brazil, Cyprus, and the United States, who transitioned to an entirely virtual medium of teaching during the pandemic. Sixteen faculty participated in 1:1 semi-structured interviews. Trustworthiness of qualitative inquiry was ascertained using triangulation, thick descriptions, and peer reviews. Four major themes emerged from analysis of participants’ interview data: adapting pedagogy in real-time, expected excellence, limitations of the medium, and informing future teaching practice. All participants described teaching during the pandemic as one of the most challenging experiences of their professional careers. Despite available resources, faculty noted challenges in making authentic connections with students, adapting to technological interruptions, assessment of student understanding of content, and managing work-life balance. Despite the challenges, faculty worked collaboratively with peers to innovate new approaches of creating social, cognitive, and teaching presence. Unique opportunities arose from the pandemic to enhance future teaching practice.

Liver transplant recipients infected with SARS-CoV-2 in the early postoperative period: Lessons from a single center in the epicenter of the pandemic

The impact of coronavirus disease‐19 (COVID‐19) in liver recipients remains largely unknown. Most data derive from small retrospective series of patients transplanted years ago. We aimed to report a single‐center case series of five consecutive patients in the early postoperative period of deceased‐donor liver transplantation who developed nosocomial COVID‐19. Two patients presented important respiratory discomfort and eventually died. One was 69 years old and had severe coronary disease. She rapidly worsened after COVID‐19 diagnosis on 9th postoperative day. The other was 67 years old with non‐alcoholic steatohepatitis, who experienced prolonged postoperative course, complicated with cytomegalovirus infection and kidney failure. He was diagnosed on 36th postoperative day and remained on mechanical ventilation for 20 days, ultimately succumbing of secondary bacterial infection. The third, fourth, and fifth patients were diagnosed on 10th, 11th, and 18th postoperative day, respectively, and presented satisfactory clinical evolution. These last two patients were severely immunosuppressed, since one underwent steroid bolus for acute cellular rejection and another also used anti‐thymocyte globulin for treating steroid‐resistant rejection. Our novel experience highlights that COVID‐19 may negatively impact the postoperative course, especially in elder and obese patients with comorbidities, and draws attention to COVID‐19 nosocomial spread in the early postoperative period.
