Occupational accidents in mining workers: scoping review of studies published in the last 13 years.

Objective: Mining activity represents one of the most hazardous occupations related to health, with 8% of fatal injuries concentrated in this sector worldwide. Thus, it is crucial to timely identify the factors involved in such injuries. We aimed to explore the sociodemographic and occupational/organisational factors associated with injuries, causative agents and subsequent disabilities and fatality of workers exposed to occupational injuries in the mining sector.

Effect of goal-directed haemodynamic therapy guided by non-invasive monitoring on perioperative complications in elderly hip fracture patients within an enhanced recovery pathway.

Background: Goal-directed haemodynamic therapy (GDHT) has been shown to reduce morbidity and mortality in high-risk surgical patients. However, there is little evidence of its efficacy in patients undergoing hip fracture surgery. This study aims to evaluate the effect of GDHT guided by non-invasive haemodynamic monitoring on perioperative complications in patients undergoing hip fracture surgery.

Optimization of buffer solutions to analyze inflammatory cytokines in gingival crevicular fluid by multiplex flow cytometry.

Objective: the aim of this study was to test two buffer solutions in order to attain a reliable and reproducible analysis of inflammatory cytokines (IL-1β, IL-6, TNF-α, OPG, OPN and OC), in gingival crevicular fluid (GCF) by flow cytometry.

Material And Methods: GCF samples from healthy volunteers were collected with perio-paper strips and diluted either in phosphate buffered saline (PBS) or Tris-HCl buffer, with and without protease inhibitors (PI). Cytokine immunoassays were carried out by flow cytometry (Luminex Xmap 200) generating standard curves.

Calcitonin gingival crevicular fluid levels and pain discomfort during early orthodontic tooth movement in young patients.

Objectives: To investigate the previously unreported presence of calcitonin (CT) levels in gingival crevicular fluid (GCF), its variations during initial orthodontic tooth movement in both tension and compression sites, and its possible association with the experienced dental pain.

Design: Fifteen children (mean age: 12.6 years) requiring orthodontic closure of the upper midline diastema were included.

Biochemical markers of bone metabolism in gingival crevicular fluid during early orthodontic tooth movement.

Objective: To evaluate the expression of an activator of nuclear factor-kappa (RANK), osteoprotegerin (OPG), osteopontin (OPN), and transforming growth factor ß1 (TGF-ß1) in gingival crevicular fluid (GCF) of teeth subjected to orthodontic forces.

Materials And Methods: A randomized, pilot clinical trial including 10 healthy volunteers was conducted using a split-mouth design. Orthodontic elastic separators were placed between the second premolar and first molar, with the contralateral quadrant serving as a control.
