Objective To provide insights into the nature, risk factors, impact and existing measures for reporting and preventing violence in the healthcare system. The under-reporting of violence against healthcare workers (HCWs) globally highlights the need for increased public awareness and education.Methods The Violence Study of Healthcare Workers and Systems study used a survey questionnaire created using Research Electronic Data Capture (REDCap) forms and distributed from 6 June to 9 August 2022. Logistic regression analysis evaluated violence predictors, including gender, age, years of experience, institution type, respondent profession and night shift frequency. A χ2 test was performed to determine the association between gender and different violence forms.Results A total of 5405 responses from 79 countries were analysed. India, the USA and Venezuela were the top three contributors. Female respondents comprised 53%. The majority (45%) fell within the 26–35 age group. Medical students (21%), consultants (20%), residents/fellows (15%) and nurses (10%) constituted highest responders. Nearly 55% HCWs reported firsthand violence experience, and 16% reported violence against their colleagues. Perpetrators were identified as patients or family members in over 50% of cases, while supervisor-incited violence accounted for 16%. Around 80% stated that violence incidence either remained constant or increased during the COVID-19 pandemic. Among HCWs who experienced violence, 55% felt less motivated or more dissatisfied with their jobs afterward, and 25% expressed willingness to quit. Univariate analysis revealed that HCWs aged 26–65 years, nurses, physicians, ancillary staff, those working in public settings, with >1 year of experience, and frequent night shift workers were at significantly higher risk of experiencing violence. These results remained significant in multivariate analysis, except for the 55–65 age group, which lost statistical significance.Conclusion This global cross-sectional study highlights that a majority of HCWs have experienced violence, and the incidence either increased or remained the same during the COVID-19 pandemic. This has resulted in decreased job satisfaction.

Se cuantificaron y compararon los melanomacrófagos (MM) y la actividad de la enzima Glutatión S−Transferasa (GST) en hígados de ejemplares adultos de Leptodactylus chaquensis (Anura, Leptodactylidae) colectados en un cultivo de arroz (CA) (siete días posteriores a la aplicación de clorpirifos, CPF) y en un sitio de referencia (SR) en el departamento San Javier, provincia de Santa Fe (Argentina). El análisis histológico reveló una mayor cantidad (p = 0.028) y área ocupada por MM (p = 0.017) y se registró una inhibición en la actividad de la GST (p = 0.030) en individuos del CA respecto a los del SR. Los efectos descriptos evidencian el riesgo ecotoxicológico para los anuros en los cultivos de arroz con aplicaciones de CPF.

Introduction: Gattinoni et al. have recently introduced a new parameter: the “alactic base excess” (ABE). ABE is equivalent to the number of strong acids, other than lactate, which are present in the plasma in abnormal concentrations, negative ABE being associated with higher mortality in sepsis. Hemoperfusion (HPF) is an extracorporeal procedure that involves the passage of blood through an adsorption cartridge, where solutes are removed by direct binding to the sorbent material. Then, it was decided to explore the influence of HPF on negative ABE value in sepsis. Materials and methods: Basal values of ABE, standard base excess (SBE), and lactate (mean, standard deviation [SD]) were obtained. The difference between these parameter values before and after four sessions of HPF (HA330) (delta value) was evaluated. Student’s t-test and Wilcoxon test were applied. Results: From 32 patients (age: 57±13) suffering from respiratory insufficiency secondary to COVID-19 who were treated with HPF in the critical care unit of Clinica de la Mujer, Bogotá (Colombia), 6 patients presented with metabolic acidosis with negative ABE value (‒2.7±1) with negative SBE (‒4.7±1) and high lactate serum value (2±0.7 mmol/L). Delta ABE, SBE, and lactate were: 7.7 (p = 0.005), 6.1 (p = 0.003), and 1.6 (p = NS), respectively. Thus, negative ABE was significantly reversed by HPF, since SBE value turned positive without significant change in lactate. Conclusion: Negative alactic parameter was significantly reversed by HPF in septic patients. It is necessary to carry out evaluations in larger groups to estimate their impact on clinical outcomes.

Objetivo: Medición de la eficacia y relevamiento de las complicaciones asociadas a la a realización de traqueostomía percutánea (TP) guiada por videobroncoscopia en un hospital universitario de alta complejidad. Materiales y métodos: Estudio observacional retrospectivo realizado entre mayo de 2017 y agosto de 2019. El criterio para la indicación de TP fue desvinculación prolongada de la ventilación mecánica en todos los casos. Incluyó pacientes mayores de 18 años en que se realizó TP electiva guiada por videobroncoscopia. Se registraron variables demográficas, APACHE II y días de ventilación mecánica previos a la TP. La eficacia del procedimiento fue evaluada en base a la tasa de éxito en la ejecución, la necesidad de conversión a técnica abierta. Asimismo, se registraron las complicaciones observadas. Resultados: Se evaluaron 235 procedimientos (149 hombres y 86 mujeres) en pacientes con edad media de 61 años ± 19, un score APACHE II 18 ± 8. La TP pudo ser ejecutada en forma rápida y satisfactoria en todos los pacientes sin requerimiento de conversión a técnica abierta. Se presentaron complicaciones tempranas en el 3,8% (9) de los casos. El sangrado menor fue la complicación más frecuentemente observada en 5 casos (2,1%), hipotensión en 3 casos (1,3%) e hipoxemia transitoria en un caso (0,4%). Asimismo el 2,1% (5) de los casos registró complicaciones tardías. Conclusión: La realización de TP mediante la técnica de dilatador único guiada por videobroncoscopia se describe como un procedimiento efectivo y seguro, que puede realizarse en unidades de cuidados intensivos con baja tasa de complicaciones.

Introduction: oxidative stress and inflammation associated with insulin resistance (IR) contribute to the generation of non-alcoholic steatohepatitis. Also, exposure to glyphosate, a widely used herbicide, increases hepatic lipid peroxidation with increased free radicals of O2. Objectives: to evaluate the effects of the prolonged administration of a herbicide based on glyphosate on the generation of IR, oxidative stress and hepatic histological changes in animals treated with a sucrose rich diet (DRS).
