Mental health in medical residents: relationship with personal, work-related, and sociodemographic variables

“…These data underscore the need to address this problem, since alcohol dependence implies several impairments for professionals and patients alike. 5,12,13 In addition to specialty, working more than eight shifts per month and 70 hours per week were also significantly associated with alcohol dependence.…”

“…9,10 Alcohol dependence, one of the main causes of absenteeism in Brazil, 11 is related to social, family, financial, interpersonal, and occupational impairments. [12][13][14] The presence of these problems in medical residents has been associated with increased rate of self-reported errors, adoption of suboptimal practices in patient care, and thoughts of suicide or death. 2,4,15 Sociodemographic and work characteristics, such as gender, age, work hours and number of shifts have been investigated as possible determinants of mental health in medical residents.…”

Laboratory weathering studies to evaluate the water quality impact of a lithium mining in Portugal

“…The exceptions were aluminium, sodium, and potassium, which were present in high concentrations in the weathering solutions and had concentrations higher than those found in the surrounding surface and ground waters. As noted by Ramos and Barriga (1994) The intrusion of aplitopegmatitic veins (lithiniferous, stanniferous, or mixed veins) led to the recrystallization of sodium feldspar (albite) and K-feldspar, as well as silica deposition in the regional granites. Additionally, the study highlights the presence of lithium in the soil, with concentrations varying between 1,673 ± 908 ppm in stanniferous sills and 5,845 ± 1,832 ppm in lithiniferous sills.…”
