Handwashing (HW) with water and soap is one of the cheapest and most effective ways of protecting oneself and others against the coronavirus. Here, the HW knowledge, attitudes, and practices of Saudi adults were assessed during the COVID-19 pandemic using a cross-sectional study conducted between May 8 and June 8, 2020, during a partial lockdown period. A web-based validated questionnaire was distributed through different social media platforms, and the sociodemographic characteristics of the participants, seven items related to knowledge, four items related to attitudes, and thirteen items related to the practice of HW were assessed. A total of 1323 (51% male and 49% female) adults from all regions of Saudi Arabia responded to the questionnaire. The overall mean (± SD) was 5.13 (± 1.18) for knowledge of HW and COVID-19, 2.79 (± 0.77) for attitude toward HW, and 7.8 (± 2.56) for HW practice. A multiple linear regression analysis revealed factors associated with knowledge to be age and family income. Sex, educational level, family income, and HW knowledge were associated with negative and neutral attitude, whereas age, sex, family income, and HW knowledge were associated with practice. These results suggest that HW knowledge was strongly associated with positive attitudes toward HW and correct HW practice in Saudi adults during the COVID-19 lockdown.

Shoulder pain is a common symptom after intramuscular vaccination. However, only a few cases of shoulder joint injury have been reported after coronavirus disease 2019 vaccination. A 52-year-old woman experienced clinically significant pain in the left shoulder joint after receiving the first dose of a coronavirus disease 2019 vaccine. She neglected the shoulder pain, hoping that it would spontaneously improve without medical attention. However, the pain continued with obvious limitations in shoulder movement and function. After 8 months, she presented to the outpatient clinic with a frozen left shoulder. Such rare consequences of vaccinations, known as shoulder injury related to vaccine administration, can be prevented by using an appropriate needle gauge and length according to the patient’s sex and weight with the correct injection site away from shoulder structures.

Background: Cardioselective beta-blockers may affect glucose or lipid profiles. Objective: We sought to compare the effects of two beta-blockers, metoprolol and bisoprolol, as the most commonly used drugs in cardiology, on glucose and lipid profiles in patients with cardiovascular diseases. Methods: We conducted a retrospective cross-sectional matched study at Prince Sultan Cardiac Center in Burydah in August 2017. Patient records were screened, and adult patients with cardiovascular disorders who were treated with a stable dose of metoprolol or bisoprolol were included. Parameters related to glucose and lipid metabolism were compared using the Student’s t-test between the two groups. Results and Conclusion: The metoprolol and bisoprolol arms included 204 and 200 patients, respectively.
