To study the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after pandemic's peak and before the vaccine enrollment in Riyadh, Saudi Arabia and further explore predictors for SARS-CoV-2 positivity. ⋯ The seroprevalence of SARS-CoV-2 among the blood donors in Riyadh, Saudi Arabia is considerably lower than the percentages necessary for herd immunity. Developing SARS-CoV-2-symptoms is the critical factor for higher seropositivity after SARS-CoV-2 exposure.

To measure the effectiveness of tranexamic acid (TXA); in total joint arthroplastyin terms of reducing post-operative blood loss. ⋯ Tranexamic acid use in TKA and THA is effective in reducing post-operative blood loss in terms of drop in Hg level, total drainage output and blood transfusion rate.
-
To evaluate the role of adjuvant radiation therapy in patients with locoregionally recurrent (rpT4/N1b) papillary thyroid carcinoma (PTC). ⋯ Adjuvant radiation therapy ensured favorable locoregional recurrence-free survival in patients with rT4/N1b PTC and might contribute to improving patients' quality of life by reducing the need for additional salvage surgery and the economic burden of other salvage treatments, such as surgery or radioactive iodine therapy.
-
To determine how well ultrasound-guidance percutaneous radiofrequency ablation (RFA) and microwave ablation (MWA) performed for benign symptomatic thyroid nodules in terms of clinical and functional outcomes. ⋯ Alternative therapies for benign symptomatic thyroid nodules include RFA and MWA. The findings of this research revealed that both approaches are safe and effective.

To review voiding dysfunction caused by 3 different etiologies; dysfunction voiding syndrome (DVS), neurogenic bladder secondary to spinal dysraphisim (NB), and valve bladder syndrome (VBS). ⋯ Early diagnosis and management of childhood voiding dysfunction was associated with better prognosis. Children managed conservatively have better preservation of kidney function than those who needed surgery.
