Determinants of COVID-19 vaccine hesitancy among students and parents in Sentinel Schools Network of Catalonia, Spain.

Vaccine hesitancy is defined as a delay in acceptance of vaccines despite its availability, caused by many determinants. Our study presents the key reasons, determinants and characteristics associated with COVID-19 vaccine acceptability among students over 16 years and parents of students under 16 years and describe the COVID-19 vaccination among students in the settings of sentinel schools of Catalonia, Spain. This is a cross-sectional study that includes 3,383 students and the parents between October 2021 and January 2022.

The COVID-19 Sentinel Schools Network of Catalonia (CSSNC) project: Associated factors to prevalence and incidence of SARS-CoV-2 infection in educational settings during the 2020-2021 academic year.

The Sentinel Schools project was designed to monitor and evaluate the epidemiology of COVID-19 in Catalonia, gathering evidence for health and education policies to inform the development of health protocols and public health interventions to control of SARS-CoV-2 infection in schools. The aim of this study was to estimate the prevalence and incidence of SARS-CoV-2 infections and to identify their determinants among students and staff during February to June in the academic year 2020-2021. We performed two complementary studies, a cross-sectional and a longitudinal component, using a questionnaire to collect nominal data and testing for SARS-CoV-2 detection.

The first year of the COVID-19 pandemic in an indigenous population in Brazil: an epidemiological study.

This cross-sectional observational study that describes the epidemiological data of the first year of the COVID-19 pandemic in the Mato Grosso do Sul State, aimed to demonstrate the differences between indigenous and non-indigenous populations, characterize confirmed cases of COVID-19 according to risk factors related to ethnicity, comorbidities and their evolution and to verify the challenges in facing the disease in Brazil. SIVEP-Gripe and E-SUS-VE, a nationwide surveillance database in Brazil, from March 2020 to March 2021 in Mato Grosso do Sul state, were used to compare survivors and non-survivors from indigenous and non-indigenous populations and the epidemiological incidence curves of these populations. A total of 176,478, including 5,299 indigenous people, were confirmed.

Seroprevalence of SARS-CoV-2 in Emergency Department Healthcare Workers at Sírio-Libanês Hospital, Brazil.

COVID-19 has spread rapidly worldwide. Information on its prevalence and factors associated with infection are important for protecting both professionals and patients in healthcare centers. This study evaluated the seroprevalence of antibodies against SARS-CoV-2 and its association with the degree of exposure and use of personal protective equipment by healthcare professionals dedicated to the treatment of patients with flu-like illnesses in the emergency room.

HIV and SARS-CoV-2 Co-infection: Epidemiological, Clinical Features, and Future Implications for Clinical Care and Public Health for People Living with HIV (PLWH) and HIV Most-at-Risk Groups.

Purpose Of Review: The purpose of this review is to use the currently available clinical and epidemiological data, to identify key aspects to improve both the clinical management and public health response to SARS-CoV-2/HIV co-infection among HIV vulnerable populations and people living with HIV (PLWH).

Recent Findings: While at the beginning of the COVID-19 pandemic, the lack of robust information on SARS-CoV-2/HIV co-infection, prevented a clear picture of the synergies between them, currently available data strongly support the importance of common structural factors on both the acquisition and clinical impact of these infections and the relevance of age, comorbidities, and detectable HIV viral load as associated worse prognostic factors among PLWH. Although more information is needed to better understand the biological, clinical, and epidemiological relationship between both infections, a syndemic approach to prevent SARS-CoV-2 among HIV high-risk groups and PLWH, targeting these populations for SARS-CoV-2 vaccines and protocolizing early identification of PLWH with worse COVID-19 prognosis factors, is crucial strategies to decrease the overall impact of SARS-CoV-2 /HIV co-infection.

HIV and SARS-CoV-2 Co-infection: Epidemiological, Clinical Features, and Future Implications for Clinical Care and Public Health for People Living with HIV (PLWH) and HIV Most-at-Risk Groups.

Purpose Of Review: The purpose of this review is using the currently available clinical and epidemiological data, to identify key aspects to improve both the clinical management and public health response with regard SARS-CoV-2/HIV co-infection among HIV vulnerable populations and people living with HIV (PLWH).

Recent Findings: While at the beginning of the COVID-19 pandemic, the lack of robust information on SARS-CoV-2/HIV coinfection prevented to have a clear picture of the synergies between them, currently available data strongly supports the importance of common structural factors on both the acquisition and clinical impact of these infections and the relevance of age, co-morbidities, and HIV viral load as associated worse prognosis factors among PLWH. Although more information is needed to better understand the biological, clinical, and epidemiological relationship between both infections, in the meanwhile, syndemic approaches to prevent SARS-CoV-2 among HIV higher risk groups and PLWH, targeting these population for SARS-CoV-2 vaccines and protocolizing early identification of HIV + patients with worse COVID-19 prognosis factors, are crucial strategies to decrease the overall impact of SARS-CoV-2 /HIV coinfection.

Ganglionar tuberculosis infection evolving to hemophagocytic lymphohistiocytosis after anti-programmed cell death 1 treatment for high-risk melanoma: a case report.

Background: Hemophagocytic lymphohistiocytosis is a rare, potentially fatal syndrome of immune hyperactivation. Here we describe a ganglionar tuberculosis evolving to hemophagocytic lymphohistiocytosis following adjuvant immunotherapy in a melanoma patient.

Case Presentation: A 76-year-old Caucasian male with melanoma started with fever, diffuse petechiae, splenomegaly, anemia, thrombocytopenia, hypofibrinogenemia, and hyperferritinemia 2 months following completion of adjuvant treatment with nivolumab.

Imputation method to reduce undetected severe acute respiratory infection cases during the coronavirus disease outbreak in Brazil.

Introduction: The coronavirus disease (COVD-19) outbreak has overburdened the surveillance of severe acute respiratory infections (SARIs), including the laboratory network. This study was aimed at correcting the absence of laboratory results of reported SARI deaths.

Methods: The imputation method was applied for SARI deaths without laboratory information using clinico-epidemiological characteristics.

Stent evaluation by coronary computed tomography angiography: a comparison between Iopamidol-370 and Ioversol-320 hypo-osmolar iodine concentration contrasts.

Objective: Qualitative and quantitative image analysis between Iopamidol-370 and Ioversol-320 in stents´ evaluation by coronary computed tomography angiography (CTA).

Methods: Sixty-five patients with low-risk stable angina undergoing stent follow-up with coronary CTA were assigned to Iopamidol I-370 ( = 33) or Ioversol I-320 ( = 32) in this prospective, double-blind, non-inferiority, randomized trial. Stent lumen image quality was graded by 5-point Likert Scale.

A model to predict SARS-CoV-2 infection based on the first three-month surveillance data in Brazil.

Objective: COVID-19 diagnosis is a critical problem, mainly due to the lack or delay in the test results. We aimed to obtain a model to predict SARS-CoV-2 infection in suspected patients reported to the Brazilian surveillance system.

Methods: We analysed suspected patients reported to the National Surveillance System that corresponded to the following case definition: patients with respiratory symptoms and fever, who travelled to regions with local or community transmission or who had close contact with a suspected or confirmed case.

Predicting Hospital Admission and Prolonged Length of Stay in Older Adults in the Emergency Department: The PRO-AGE Scoring System.

Study Objective: We developed prediction models for hospital admission and prolonged length of stay in older adults admitted from the emergency department (ED).

Methods: This was a retrospective cohort study of patients aged 70 years or older who visited a geriatric ED in Brazil (N=5,025 visits). We randomly allocated participants to derivation and validation samples in a 2:1 ratio.

Hepatitis E infection is an infrequent cause of acute hepatitis in the metropolitan area of Buenos Aires.

Unlabelled: Background Argentina is considered a region of low seroprevalence of hepatitis E virus (HEV), however; no studies have evaluated its burden among acute hepatitis cases.

Objectives: We aimed to estimate the proportion of acute HEV and outcome in a cohort of patients with acute hepatitis from 6 liver units in the Metropolitan area of Buenos Aires (MABA).

Study Design: We performed a prospective cohort study including patients ≥18 years with acute hepatitis (increase in transaminases x 5 ULN) fromJuly 2016 to May 2018.

Successive blood pressure measurements to evaluate suspected and treated hypertension.

Introduction: According to the published literature, blood pressure (BP) measurements performed in the outpatient clinical setting are often inaccurate. The white coat effect and improper technique are the main causes of this imprecision. Construction of a set of readings without them could improve the accuracy of BP measurement.

Disseminating cardiopulmonary resuscitation training by distributing 9,200 personal manikins.

Objectives: Community members should be trained so that witnesses of cardiac arrests are able to trigger the emergency system and perform adequate resuscitation. In this study, the authors evaluated the results of cardiopulmonary resuscitation (CPR) training of communities in four Brazilian cities, using personal resuscitation manikins.

Methods: In total, 9,200 manikins were distributed in Apucarana, Itanhaém, Maringá, and São Carlos, which are cities where the populations range from 80,000 to 325,000 inhabitants.

The bleeding risk score as a mortality predictor in patients with acute coronary syndrome.

Background: It is well known that the occurrence of bleeding increases in-hospital mortality in patients with acute coronary syndromes (ACS), and there is a good correlation between bleeding risk scores and bleeding incidence. However, the role of bleeding risk score as mortality predictor is poorly studied.

Objective: The main purpose of this paper was to analyze the role of bleeding risk score as in-hospital mortality predictor in a cohort of patients with ACS treated in a single cardiology tertiary center.
