Resumen
El trabajo por turnos rotativos, especialmente con turnos nocturnos frecuentes, aumenta los riesgos de enfermedades cardiovasculares como el aumento de peso y la rigidez arterial. La reducción de los turnos nocturnos puede ayudar a mitigar estos impactos negativos en la salud.
Área de la Ciencia:
- Salud en el trabajo
- Medicina cardiovascular
- Fisiología
Sus antecedentes:
- El trabajo por turnos es frecuente en las industrias y puede afectar a la salud cardiovascular.
- Los datos longitudinales sobre los factores de riesgo de enfermedades cardiovasculares (ECV) en los trabajadores por turnos son limitados.
- Comprender estos cambios es crucial para desarrollar intervenciones de salud específicas.
Objetivo del estudio:
- Evaluar los niveles absolutos y los cambios a 6 años en los factores de riesgo de ECV.
- Comparar estos cambios entre los trabajadores por turnos industriales (carga nocturna alta/baja) y los trabajadores diurnos.
- Identificar las asociaciones entre las características del trabajo por turnos y la progresión del factor de riesgo de ECV.
Principales métodos:
- Un estudio de seguimiento de 6 años de 3 grupos industriales: trabajadores de turnos de alta carga nocturna, trabajadores de turnos de baja carga nocturna y trabajadores diurnos.
- La recopilación de datos incluyó datos demográficos, presión arterial, frecuencia cardíaca, espesor de la carótida íntima-media (cIMT), velocidad de onda del pulso de la carótida al fémur (cfPWV), V̇O2max, lípidos, HbA1c y CRP.
- Se utilizaron modelos mixtos para analizar los cambios longitudinales y las diferencias de grupo.
Principales resultados:
- Los trabajadores por turnos con alta carga nocturna mostraron aumentos en el peso, el cfPWV y el CRP.
- Los trabajadores por turnos con baja carga nocturna y los trabajadores diurnos mostraron aumentos en la CIMT.
- Todos los trabajadores experimentaron una disminución de V·O2max y un aumento de HbA1c, vinculados a años de trabajo por turnos.
Conclusiones:
- El trabajo por turnos rotativos, particularmente con turnos nocturnos significativos, se asocia con un aumento de peso, inflamación, rigidez arterial, cIMT, HbA1c y reducción de V̇O2max.
- Estrategias como reducir los turnos nocturnos e incorporar períodos de descanso pueden disminuir el riesgo de ECV.
- El trabajo por turnos plantea importantes problemas de salud cardiovascular que requieren una gestión proactiva.

01:15Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response
123
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

01:13Insufficient Sleep and Sleep Deprivation
210
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

77
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.

01:26Factors Affecting the Risk of Infection
12.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:23Insulation Coordination
226
Insulation coordination is the process of matching electric equipment's insulation strength with protective device characteristics to protect the equipment against expected overvoltages. This selection is based on engineering judgment and cost. Equipment can generally withstand short-duration high transient overvoltages, but repeated tests with identical waveforms can yield inconsistent results. As a result, standard impulse voltage waveforms are used for testing, defined by specific times...
