ABSTRACT

OBJECTIVE: We sought to test whether a 2-week Total Worker Health (TWH) training mapped to TWH education competencies could be administered to a Mexican audience of occupational safety and health professionals and could lead to positive changes to knowledge and behaviors. METHODS: This study used robust program evaluation methods collected before and after each of the nine training days and at the end of the course. RESULTS: Overall course quality received a mean score of 4.6 (SD = 0.6) and 98.8% of participants agreed that their TWH knowledge increased. All participants intended to make at least one change to their professional practice, most frequently helping companies assess their organizational culture to support health, safety, and well-being. CONCLUSIONS: This TWH training was well received and led to positive self-reported increase in knowledge and abilities to influence workers' health, safety, and well-being.

ABSTRACT

Background: Despite the extensive distribution of COVID-19 vaccines across Latin America, research on their real-world performance remains limited. We aimed to evaluate the effectiveness of five vaccines (BNT162b2, AZD1222, CoronaVac, Gam-COVID-Vac, and Ad5-nCoV) in a cohort of 2,559,792 pensioners covered by the Mexican Institute of Social Security. Methods: We conducted a nested test-negative design study on 28,271 individuals tested for SARS-CoV-2 infection between April and November 2021, accounting for 29,226 separate episodes. We used mixed-effects logistic regression models to estimate the vaccine effectiveness (VE) in fully vaccinated individuals for symptomatic infection, hospitalization, severe disease, and death. Findings: The median age of the study population was 70 years (interquartile range 65-76) and 76.4% (21,598/28,271) were male. VE rates were 56.3%, 75.3%, 79.7%, and 79.8% against symptomatic infection (95% confidence interval [CI]: 53.5-59.0), hospitalization (95% CI: 73.4-77.0), severe disease (95% CI: 78.0-81.3), and death (95% CI: 78.1-81.4), respectively. When evaluating vaccines individually, all showed moderate to high VE, with the best being BNT162b2 (symptomatic infection, 69.8%, 95% CI: 67.3-72.0; hospitalization, 84.1%, 95% CI: 82.5-85.6; severe disease, 88.2%, 95% CI: 86.7-89.5; and death, 88.3%, 95% CI: 86.9-89.6) and Gam-COVID-Vac (symptomatic infection, 70.0%, 95% CI: 64.8-74.4; hospitalization, 86.8%, 95% CI: 83.7-89.3; severe disease, 91.9%, 95% CI: 89.4-93.9; and death, 92.0%, 95% CI: 89.5-93.9). Interpretation: All five SARS-CoV-2 vaccines available for this population showed moderate to high levels of protection against COVID-19 and its progression to severe outcomes.

ABSTRACT

Resumen: Objetivo: Establecer criterios médicos de retorno al trabajo en personal con riesgo de complicaciones por Covid-19. Material y métodos. Se realizó una revisión sistemática para identificar las condiciones y las características clínicas que influyen en el riesgo de desarrollar Covid-19 grave. Resultados: Se ha demostrado incremento del riesgo en obesidad, edad >60 años, diabetes mellitus, hipertensión arterial, enfermedad pulmonar obstructiva crónica, enfermedad cardiovascular, enfermedad renal crónica y cáncer. Solamente en diabetes se ha estudiado si el control previo influye. Se proponen condiciones específicas y el nivel de riesgo epidemiológico para el retorno al trabajo. Conclusiones: El retorno laboral de estos grupos debe priorizarse buscando favorecer el control de la enfermedad, identificando el estado de salud que incrementa el riesgo y protegiendo el derecho al trabajo. Se presentan recomendaciones para guiar la reincorporación al trabajo.


Abstract: Objective: To establish medical criteria for return to work to people with increased risk of severe illness from Covid-19. Materials and methods. We performed a systematic review to identify the conditions and clinical characteristics that influence the risk of developing severe Covid-19. Results: Increased risk has been shown in obesity, age >60 years old, diabetes mellitus, arterial hypertension, chronic obstructive pulmonary disease, cardiovascular disease, chronic kidney disease and cancer. Only in diabetes it has been studied whether prior control influences. Specific medical conditions and epidemiological risk level for return to work are proposed. Conclusions: Return to work of vulnerable groups should be prioritized, seeking to promote disease control, identifying health conditions that increase risk, and protecting the right to work. We present recommendations to guide the return to work.

ABSTRACT

El paraquat (PQ) pertenece al grupo de herbicidas de los bipiridilos. Su presentación es en forma líquida o en granulado, usándose con una concentración al 5 %, para uso en jardinería y al 20 % para uso agrícola. En la intoxicación en humanos el órgano blanco es el pulmón. Los pacientes desarrollan insuficiencia respiratoria que puede explicarse por una inicial actividad que involucra un gran estrés oxidativo, con presencia de radicales libres de oxígeno y peroxidación lipídica, con sus consecuentes daños, además de infiltración por polimorfonucleares que con su reacción de liberación empeoran la neumonitis. Puede haber mejoría de la neumonitis y el daño en algunos órganos, pero pronto la aparición de fibrosis pulmonar lleva a falta de respuesta a la administración de oxígeno y a la muerte por insuficiencia respiratoria en algunos días a semanas. De acuerdo con la cantidad ingerida varía la evolución de la severidad del cuadro clínico. Se presentan dos pacientes pediátricos con intoxicación por PQ, a quienes se les inició tratamiento inmunosupresor después de 48 horas de la exposición. Uno de los pacientes se intoxicó de manera no intencional y otro por suicidio. Los dos pacientes recibieron tratamiento similar, sin embargo, el paciente con intención suicida falleció días después de la exposición. Se hace una revisión de la literatura sobre el tratamiento administrado.


Paraquat (PQ) belongs to the bipyridyls herbicides. Its presentation is liquid or granulated, being used at concentrations of 5 %, in gardening and 20 % in agricultural use. In human poisoning, the target organ is the lung. The patients develop respiratory insufficiency that can be explained by an initial activity that involves a great oxidative stress, with the presence of oxygen free radicals and lipid peroxidation, with its consequent damages, in addition to polymorphonuclear infiltration that with its liberation reaction worsen pneumonitis. There may be improvement of pneumonitis, but the appearance of pulmonary fibrosis will lead to a lack of response to the administration of oxygen and death due to respiratory failure in a few days to a few weeks. According to the amount ingested, the evolution of the severity of the clinical picture varies. We present two pediatric patients with PQ poisoning, who were started on immunosuppressant treatment after 48 hours of exposure. One of the patients was poisoned incidentally and the other one by suicide. The two patients received similar treatment, however, the patient with suicidal intention died days after the exposure. A review of the literature on the treatment offered is made.

ABSTRACT

Se han reportado en la literatura pocos casos de intoxicación por mercurio por administración en tejidos blandos. No se cuenta con suficiente evidencia acerca del manejo con terapia quelante en este tipo de intoxicación. Se reporta el caso de una mujer de 34 años con antecedente psiquiátrico la cual se administró mercurio intramuscular en fosa cubital izquierda con fines autolíticos. Acudió al servicio de urgencias 24 horas posteriores a su administración, el motivo principal fue el dolor intenso en la zona y la presencia de edema, sin efectos sistémicos. La radiografía mostró depósitos metálicos en 1/3 de brazo, localizados en músculo, y que migraron a través de la fascia hacia 2/3 del antebrazo. La placa de tórax no mostró alteraciones. Fue intervenida quirúrgicamente en 3 ocasiones extrayendo mínimas cantidades de mercurio. La paciente fue manejada con antibióticos por presencia de celulitis. Un mes después presentó temblor mercurial, razón por la cual se tomaron muestras de sangre y orina para la determinación de mercurio, el cual resulto elevado en ambas muestras, por lo que se le administró terapia quelante con D-penicilamina.


There are just a few cases of mercury toxicity after administration in soft tissue, reported in the literature. There is insufficient evidence about the management with chelation therapy in this type of poisoning. We report the case of a 34 year-old woman with a psychiatric history who administered herself a mercury injection into de muscle in the left cubital fossa, referred as a suicide attempt. She came to the emergency department 24 hours after administration; the main reason was the intense pain in the area and the presence of edema, with no systemic effects. Radiography showed metallic deposits in 1/3 arm, located in muscle, which moved through the fascia to 2/3 of the forearm. Chest radiography was normal. She underwent surgery trhee times extracting trace amounts of mercury. The patient was managed with antibiotics by the presence of cellulite. One month later she had tremor mercuralis, so a blood and urine samples were sent to the laboratory in order to determinate mercury levels, which resulted high in both fluids, therefore chelation therapy with D-penicillamine was administered.
