Background: Coronavirus disease 2019 (COVID-19) pandemic has been associated with various risks, including the exposure of infectious agents.Objectives: The study aims at describing the incidence of blood and body fluid (BBF) exposure in a COVID-19 facility so as viral transmission potential through blood.Methods: A descriptive study of BBF exposure notified was carried out in a community hospital in Qatar.Results: In 2020, 29 needlesticks injuries were reported, which is a significant increase compared to the year 2019 (6 incidents) and 2018 (5 incidents). No evidence of SARS-CoV-2 transmission was shown concerning the injury using symptoms monitoring and lab test.Conclusion: The increased risk of BBF exposure during the pandemic provides insight into the need to review the prevention practices of occupational exposure during pandemics. Additional studies are required to define the risk of COVID-19 related to occupational exposure to BBF.

Background: Common cancers such as colon, breast, and lung cancer are increasing in developing countries.
Objective: This study was conducted to determine 10-year trends and changes in common cancers in patients from a referral hospital in Tehran, Iran.
Methods: This cross-sectional study investigated a study population comprising colon, stomach, lung, prostate, and breast cancer patients registered at the cancer center of a referral hospital in Tehran, Iran from April 1, 2007 to the end of March, 2016 (n=4472). Inclusion criteria were a definitive diagnosis of cancer and an age between 15 and 75 years. Data was entered into SPSS (version 18) software and analyzed using the Time Series analysis and Scatter IO graph.
Results: Significant correlations (P value <0.001) were seen between age increases in patients and the increasing number of patients in any type of cancer. With almost all of the five studied cancers, incidence increased with aging (P value <0.001). The incremental linear trend in the age of patients with lung (P value = 0.008) and colon (P value = 0.004) cancers and the decreasing trend in the age of prostate cancer patients (P value = 0.001) were statistically significant.
Conclusion: The incidence of cancer has increased over the past 10 years in both genders and ages. It is suggested that future studies should address the causes and factors behind the increasing incidence of common cancers.

Introduction: Coronary artery anomalies are rare clinical entities reported in 0.6% to 5.6% of diagnostic coronary angiographies. Anomalous origins of coronary arteries from distal segments are rarely reported. Presented herein is a coronary anomaly in which the circumflex artery (CX) originated as a continuation of the posterolateral branch of the right coronary artery (RCA) with separate left anterior descending (LAD) artery origination from the left sinus of Valsalva. The clinical presentation of such a rare anomaly is discussed, and the current literature regarding the congenital absence of CX is reviewed. Case Presentation: A 66-year-old male presented with angina pectoris. Coronary angiography revealed critical stenosis in the mid segment of the LAD artery and an anomalous origin of CX artery from the distal RCA. The CX was coursing as a continuation of the posterolateral branch of the RCA. Coronary angioplasty and stent deployment was performed for the LAD lesion, and the patient was discharged with medical therapy. The patient did not report recurrent anginal symptoms under medical therapy. Conclusion: The congenital absence of the circumflex coronary artery is a rare coronary anomaly. The clinical presentation may vary, though most cases are asymptomatic during diagnosis. Such cases require close clinical follow-up since they entertain a future risk for being symptomatic, especially in the setting of atherosclerotic disease.
