AI Article Synopsis
- The study aimed to determine how working conditions affect sleepiness in truck drivers while driving.
- It involved 670 male truck drivers in Brazil who completed a questionnaire about their demographics, behaviors, and working conditions.
- Key findings revealed that long distances traveled (over 1,000 km) and productivity-based pay contracts were linked to increased sleepiness, with additional factors like illicit substance use also playing a role.
Article Abstract
The objective of this study is to identify the role of working conditions as predictors of sleepiness while driving among truck drivers. This was a cross-sectional study carried out among truck drivers who transported grains to Paranaguá Port, Paraná, Brazil. The truck drivers were interviewed and completed a self-administered questionnaire to collect data on sociodemographic and behavioral variables, working conditions, consumption of illicit psychoactive substances, and sleep patterns. Drivers were considered to be sleepy while driving if they reported a medium or high probability of napping while driving at night, during the daytime, or while stopped in traffic. The statistical analysis used logistic regression models progressively adjusted for age, behavioral variables, sleep duration, and other working conditions. In total, 670 male drivers, with a mean age of 41.9 (±11.1) years, were enrolled. The prevalence of sleepiness while driving was 31.5%. After model adjustments, the following working conditions were associated with sleepiness while driving: Distance from the last shipment of more than 1,000 km (odds ratio [OR] = 1.54; 95% confidence interval [CI], 1.07-2.23) and a formal labor contract with a productivity-based salary (OR = 2.65; 95% CI, 1.86-3.78). Consumption of illicit psychoactive substances (OR = 1.99; 95% CI, 1.14-3.47) was also associated with sleepiness while driving. Distance traveled and a formal labor contract with productivity-based earnings were the working conditions associated with sleepiness while driving, regardless of other working or behavioral characteristics, age, consumption of illicit psychoactive substances, and sleep duration.

ConspectusZinc metal batteries (ZMBs) appear to be promising candidates to replace lithium-ion batteries owing to their higher safety and lower cost. Moreover, natural reserves of Zn are abundant, being approximately 300 times greater than those of Li. However, there are some typical issues impeding the wide application of ZMBs.

Mercury is a pervasive global pollutant, with primary anthropogenic sources including mining, industrial processes, and mercury-containing products such as dental amalgams. These sources release mercury into the environment, where it accumulates in ecosystems and enters the food chain, notably through bioamplification in marine life, posing a risk to human health. Dental amalgams, widely used for over a century, serve as a significant endogenous source of inorganic mercury.

The following text describes an analysis, ongoing for three years now, of a boy currently 12 years old, whose projective-expulsive functioning becomes evident through rude and vulgar words. The image of the Cretan labyrinth and its meanders, created by Daedalus as a "protection" against the ferocity of the Minotaur, were the inspiration for this narrative. The intricate defences that imprison the patient, with their characteristics of pathological organisation, resemble a labyrinth, and through this path, the analyst and the patient go on confronting the difficulties of the process.

Background: Return-to-work (RTW) following lung transplant has been associated with increased quality of life, but little is known regarding the rates of and barriers to this in the Australian population.
Aims: We aimed to describe, characterise and determine predictors of return to work and social participation in Australian lung transplant recipients. We also sought to explore the relationship between return to work and quality of life.

Background: Previous research has indicated that long working hours are connected to a variety of health conditions, including nonalcoholic fatty liver disease (NAFLD). However, this association which has been observed in more population is limited. Our research is designed to evaluate the association between working hours, working type, and NAFLD.
