Objectives To assess prevalence and related factors of sleep disturbances among Saudi physicians during COVID-19 pandemic. Data were collected through a questionnaire including items about demographic characters, knowledge about covid-19 and items to assess sleep quality that were extracted from Pittsburgh Sleep Quality Index (PSQI) scale. Results Prevalence of sleep disorders was 43.9%, doctors in the age group of 31–40 years, associate consultants had a significant higher prevalence of sleep disorders. Medical interns and laboratory/pathology/microbiology doctors had a significant more difficulty in fall asleep during COVID-19, and internists and surgeons had a significant higher percent of those who used sleeping pills. Resident doctors had a significant higher percent of having trouble in staying awake, and residents and consultants had a significant higher percent of those who suffered decreased sleep duration. Sleep quality during COVID-19 was very good, fair good and very bad in 23.4%, 60% and 3.5% of HCW respectively. The study observed a negative impact of COVID-19 pandemic on HCW sleep quality. Hospitals administrations should provide optimal working hours with enough break and employ more doctors during the pandemic. Doctors experiencing sleep problems should have mandatory leaves.

Background: Colorectal cancer (CRC) is the fourth deadliest cancer, with approximately 900,000 deaths annually. CRC is a multifactorial disease in which a set of factors, including environmental, hereditary, and genetic factors, are integrated into cancer development.Studies have suggested an association between hereditary antigens in the human blood group system and the risk of different cancers. This study aimed to evaluate the relationship between blood groups and CRC risk. Methods:A record-based retrospective study was performed between January 2017 and August 2021. This study targeted patients diagnosed with CRC during the study period. Data of patients who agreed to participate were collected using a pre-structured checklist. The extracted data included patients' demographic blood groups and risk factors, including history of inflammatory bowel disease or CRC.Results: A total of 199 patients, aged 22 to 96 years (mean age: 61.6 ± 14.7 years), were included. The blood groups of 101 (50.8%), 59 (29.6%), 26 (13.1%), and 13 (6.5%) patients were O, A, B, and AB, respectively. Colon cancer was the most frequently reported cancer (155/199, 77.9%) across all blood groups and showed the highest frequency among patients with blood group O (74/155, 47.7%), without statistical significance (P = 0.111). Conclusion:Our study showed a statistically significant relationship between AB and non-O blood types and colon cancer compared to the O blood group.

Background: The World Health Organization and the United Nations International Children’s Fund recommend mothers to exclusively breastfeed their infants for the first six months of their life that should be initiated within the first hour after birth. Methods: This cross-sectional study included currently employed Saudi working mothers residing the Western region of Saudi Arabia. A self-administered questionnaire was distributed through email and social media. Each person meeting the inclusion criteria was provided informed consent, explaining the study aim, and ensuring the confidentiality of information. Data were obtained by filling out the designed Questionnaire. Result: This study included 692 working Saudi mothers. The frequency of exclusive breast feeding was 40.2%, which was continued by 29.8% only after returning to the work. Insufficient breast milk secretion (17.5%) and the lack or minimal support from the workplace for EBF (6.6%) were commonly stated by the mothers. There were great deficiencies in the breastfeeding friendly work policies including the absence of breast feeding or breast milk-pumping place (86.4%), absence of breastfeeding hours during work time (80.9%), and the presence of a strict full-time schedule that did not allow freely use of the nursing break. Conclusion: The present study shows low prevalence of exclusive breast feeding among working mothers in the Western region of Saudi Arabia. Multiple barriers to continuing breast feeding have been detected. Insufficient breast milk secretion and the lack of breastfeeding friendly work policies were common reasons.
