RESUMO
Background: In the Kingdom of Saudi Arabia (KSA), the labor market is thriving, employing a large workforce in occupations that carry a high risk for traumatic injuries such as construction, transportation, and manufacturing. These jobs usually involve physical exertion, power tools, high-voltage electricity, working at heights, and exposure to bad weather conditions that could potentially lead to injury. This study aimed to determine patterns of traumatic occupational injuries in Riyadh, KSA. Methods: A cross-sectional study was conducted at King Khalid Hospital and Prince Sultan Centre for Healthcare, Prince Sattam bin Abdulaziz University Hospital, and the Al-Kharj Military Industries Corporation Hospital in Al-Kharj City in the KSA between July 2021 and 2022. Descriptive analysis elucidated the type, severity, and patterns of management of non-fatal traumatic occupational injuries. A Kaplan-Meier survival curve and Weibull model for length of hospital stay adjusted for age, gender, nationality, cause for injury, and injury severity scale (ISS) scores were constructed. Results: A total of 73 patients with a mean age of 33.8 ± 14.1 years were included in the study. The most common cause of occupational injury was falling from height (87.7%). The median length of hospital stay was 6 days (IQR: 4 - 7), with no mortalities. In the adjusted survival model, compared to migrants, Saudi nationals had a 45% lower median hospital stay (-62 to - 21), P < 0.01, and every 1-point increase in ISS was associated with a 5% increase in median length of hospital stay (CI: 3 - 7, P < 0.01). Conclusion: Being a Saudi national and having lower ISS scores were associated with shorter durations of hospital stay. Our findings indicate the need for improved occupational safety measures, especially among migrant, foreign-born, and ethnic minority workers.
RESUMO
BACKGROUND: Tobacco smoking is a major health issue worldwide. In addition to several health problems, smoking can also cause buccal cavity ulcers and buccal cavity cancer in case of chronic smoking. Tobacco smoking may also lead to deranged morphology of red blood cells (RBCs), which results in reduced oxygen carrying capacity of the blood. AIM: (a) To investigate and compare the changes in the RBC morphology of smokers and nonsmokers. (b) To investigate and compare the normal buccal flora of smokers and nonsmokers. METHODOLOGY: A total of 81 men were included in the study. Study population was divided into two groups: group 1; smokers (n = 50) and group 2; nonsmokers, which served as control (n = 31). After informed written consent from the study participants, a 5 mL of venous blood was drawn under sterile conditions for complete blood analysis and RBC morphology. Samples from buccal cavity were collected by cotton swab and cultured in sterile petri dishes to identify the bacterial growth. Data of RBC morphology and buccal microbiota were compared between smokers and nonsmokers. RESULTS: Buccal microflora results showed heavy growth in smokers compared with nonsmokers. Mean values of RBCs, Platelets, WBCs, HGB (hemoglobin), and MCV (mean corpuscular volume) did not differ between smokers and nonsmokers. Mean red cell distribution (RDW) width significantly was lower in smokers than nonsmokers. Macrocytic RBCs was more in smokers (60%) compared with nonsmokers (4%). CONCLUSIONS: Our results showed an increase in the percentage of macrocytic RBCs and a decrease in the red cell distribution width (RDW) in smokers compared with nonsmokers. Buccal Microflora was significantly higher in smoker group in contrast to nonsmoker group.
