Objectives: To study the knowledge, attitude and practice level among young Saudi adults regarding osteoporosis. Methods: A cross-sectional study was done in Riyadh among Saudis, within the age group (17–30 years old), with sample size (663). A validated questionnaire was distributed in paper and electronic forms. The questionnaire had five parts: first part was the demographic variables, second part the source of the participant knowledge about the disease, third part assessed the knowledge about osteoporosis, fourth part assessed osteoporosis attitudes, and the fifth part assessed the practice for prevention of osteoporosis. The collected data was analysed by Statistical Package for the Social Sciences program. Results: It was found that there was low level of knowledge among overall participants; there was no significant difference between male and female in level of knowledge, while the age group 21–25 had the highest knowledge level among all other age groups. Males have better level of practice of a healthy lifestyle that decreases the risk of osteoporosis than females. In total, 52.5% of males have a sufficient level of practice, while only 34.9% of females have acceptable level of practice Conclusion: The study found no significant difference between males and females regarding the knowledge of osteoporosis. Males were found to have better level of practice of a healthy lifestyle that decreases the level of osteoporosis then females. The study recommends similar studies and undertake more efforts in promotion of preventive programs for young adults.

To determine the risk factors and complications of transthoracic computed tomography (CT)-guided core needle lung biopsy. This is a retrospective study of 124 patients who underwent CT-guided core lung biopsy in King Khalid University Hospital (KKUH), Riyadh. This retrospective study was conducted between January 2016 and January 2020. Patient data were collected using a standardized data form that was entered into an Excel sheet in accordance with the variables. The Statistical Package for the Social Sciences software (SPSS, version 24.0 [SPSS Inc., Chicago, IL, USA]) was used to compute for the risk of complications after CT-guided core lung biopsy and perform all statistical comparisons, and the results were reported. The overall complication rate due to CT-guided core needle biopsy was 34.7% (43) (P<0.001) of the total sample. Of the total complications, 69.76% (n = 30) had pneumothorax, 20.94% (n = 9) had hemorrhage, 6.98% (n = 3) had both pneumothorax and hemorrhage, and 2.32% (n = 1) had both air embolism and pneumothorax. Of all patients who developed pneumothorax, 20% (n = 6) required chest tube insertion. Patients with secondary chronic obstructive pulmonary disease (COPD) had a complication rate of 80% among the whole sample. Lung lesions less than 3 cm had a complication rate of 48.8% (P<0.034). The needle size showed a higher rate of complications between 20 and 18 gauge with 47.4% (n = 9) and 32.4% (n = 34), respectively. We conclude that CT-guided lung biopsy is a well-established low-risk procedure that is less invasive. However, it still carries a risk of complications with some risk factors, such as small lung lesion size and secondary COPD.
